91 Case Study 2 - Contoso Ltd Overview Existing Environment Contoso, Ltd. is a manufacturing company that produces outdoor equipment Contoso has quarterly board meetings for which financial analysts manually prepare Microsoft Excel reports, including profit and loss statements for each of the company's four business units, a company balance sheet, and net income projections for the next quarter. Data and Sources Data for the reports comes from three sources. Detailed revenue, cost and expense data comes from an Azure SQL database. Summary balance sheet data comes from Microsoft Dynamics 365 Business Central. The balance sheet data is not related to the profit and loss results, other than they both relate to dates. Monthly revenue and expense projections for the next quarter come from a Microsoft SharePoint Online list. Quarterly projections relate to the profit and loss results by using the following shared dimensions: date, business unit, department, and product category. Net Income Projection Data Net income projection data is stored in a SharePoint Online list named Projections in the format shown in the following table. Revenue projections are set at the monthly level and summed to show projections for the quarter. Balance Sheet Data The balance sheet data is imported with final balances for each account per month in the format shown in the following table. There is always a row for each account for each month in the balance sheet data. Dynamics 365 Business Central Data Business Central contains a product catalog that shows how products roll up to product categories, which roll up to business units. Revenue data is provided at the date and product level. Expense data is provided at the date and department level. Business Issues Historically, it has taken two analysts a week to prepare the reports for the quarterly board meetings. Also, there is usually at least one issue each quarter where a value in a report is wrong because of a bad cell reference in an Excel formula. On occasion, there are conflicting results in the reports because the products and departments that roll up to each business unit are not defined consistently. Planned Changes Contoso plans to automate and standardize the quarterly reporting process by using Microsoft Power Bl. The company wants to how long it takes to populate reports to less than two days. The company wants to create common logic for business units, products, and departments to be used across all reports, including, but not limited, to the quarterly reporting for the board. Technical Requirements Contoso wants the reports and datasets refreshed with minimal manual effort The company wants to provide a single package of reports to the board that contains custom navigation and links to supplementary information. Maintenance, including manually updating data and access, must be minimized as much as possible. Security Requirements The reports must be made available to the board from powerbi.com. A mail-enabled security group will be used to share information with the board. The analysts responsible for each business unit must see all the data the board sees, except the profit and loss data, which must be restricted to only their business unit's data. The analysts must be able to build new reports from the dataset that contains the profit and loss data, but any reports that the analysts build must not be included in the quarterly reports for the board. The analysts must not be able to share the quarterly reports with anyone. Report Requirements You plan to relate the balance sheet to a standard date table in Power Bl in a many-to-one relationship based on the last day of the month. At least one of the balance sheet reports in the quarterly reporting package must show the ending balances for the quarter, as well as for the previous quarter. Projections must contain a column named RevenueProjection that contains the revenue projection amounts. A relationship must be created from Projections to a table named Date that contains the columns shown in the following table. The relationships between products and departments to business units must be consistent across all reports. The board must be able to get the following information from the quarterly reports: - Revenue trends over time - Ending balances for each account - A comparison of expenses versus projections by quarter - Changes in long-term liabilities from the previous quarter - A comparison of quarterly revenue versus the same quarter during the prior year Which DAX expression should you use to get the ending balances in the balance sheet reports? A. CALCULATE ( SUM( BalanceSheet [BalanceAmount] ), DATESQTD( 'Date'[Date] ) ) B. CALCULATE ( SUM( BalanceSheet [BalanceAmount] ), LASTDATE( 'Date'[Date] ) ) C. FIRSTNONBLANK ( 'Date' [Date] SUM( BalanceSheet[BalanceAmount] ) ) D. CALCULATE ( MAX( BalanceSheet[BalanceAmount] ), LASTDATE( 'Date' [Date] ) )

A Scenario: At least one of the balance sheet reports in the quarterly reporting package must show the ending balances for the quarter, as well as for the previous quarter. DATESQTD returns a table that contains a column of the dates for the quarter to date, in the current context. Reference: https://docs.microsoft.com/en-us/dax/datesqtd-function-dax

135 You have a line chart that shows the number of employees in a department over time. You need to see the total salary costs of the employees when you hover over a data point. What are possible way to achieve this goal? A. Add a salary to the tooltips. B. Add a salary to the visual filters. C. Add salary to the drillthrough fields.

A A: When a visualization is created, the default tooltip displays the data point's value and category. There are many instances when customizing the tooltip information is useful. Customizing tooltips provides additional context and information for users viewing the visual. Custom tooltips enable you to specify additional data points that display as part of the tooltip. B: Visual Filter applies to a single visual/tile on a report page. You can only see visual level filters selected visual on the report canvas. Incorrect Answers: C: With drill through in Power BI reports, you can create a page in your report that focuses on a specific entity such as a supplier, customer, or manufacturer. When your report readers use drill through, they right-click a data point in other report pages, and drill through to the focused page to get details that are filtered to that context. You can also create a button that drills through to details when they click it.

24 You have a data model that contains many complex DAX expressions. The expressions contain frequent references to the related and relatedtable functions. You need to recommend a solution to minimize the use of the related and relatedtable functions. What should you recommend? A. Merge tables by using Power Query. B. Hide unused columns in the model. C. Split the model into multiple models. D. Transpose.

A Combining data means connecting to two or more data sources, shaping them as needed, then consolidating them into a useful query. When you have one or more columns that you'd like to add to another query, you merge the queries. Note: The RELATEDTABLE function is a shortcut for CALCULATETABLE function with no logical expression. CALCULATETABLE evaluates a table expression in a modified filter context and returns A table of values.

You need to grant all organizational users read access to a dashboard and several reports. Solution: You create an Azure Active Directory group that contains all the users. You share each report and dashboard to the group. Does this meet the goal? A. Yes B. No

A Instead assign all the users the Viewer role to the workspace. Note: The Viewer role gives a read-only experience to its users. They can view dashboards, reports, or workbooks in the workspace, but can't browse the datasets or dataflows. Use the Viewer role wherever you would previously use a classic workspace set to "Members can only view Power BI content".

122 You have the dataset shown in the following exhibit. You need to ensure that the visual shows only the 10 cities that have the highest sales profit. What should you do? A. Add a Top N filter to the visual. B. Configure the Sales Profit measure to use the RANKX function. C. Add a calculated column to the table that uses the TOPN function. In the visual, replace Sales Profit with the calculated column. D. Add a calculated column to the table that returns the city name if the city is in the top 10, otherwise the calculated column will return "Not in Top 10". In the visual, replace Sales Profit with the calculated column.

A Power BI Top N Filters are useful to display the top performing records, and Bottom N filters are helpful to display the least performing records. For example, we can display top or bottom 10 products by orders or sales. Note: 1. Select the Column you want to display the Top Sales Profit 2. Then change the Filter Type of that Column to Top N 3. Fill in Top / Bottom number field 4. And lastly drag to the By Value filed your Sales Profit Incorrect Answers: B: You would need a filter as well.

124 Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this scenario, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You have a clustered bar chart that contains a measure named Salary as the value and a field named Employee as the axis. Salary is present in the data as numerical amount representing US dollars. You need to create a reference line to show which employees are above the median salary. Solution: You create a percentile line by using the Salary measure and set the percentile to 50%. Does this meet the goal? A. Yes B. No

A The 50th percentile is also known as the median or middle value where 50 percent of observations fall below. Reference: https://dash-intel.com/powerbi/statistical_functions_percentile.php

112 You create a dataset sourced from dozens of flat files in Azure Blob storage. The dataset uses incremental refresh. From powerbi.com, you deploy the dataset and several related reports to Microsoft Power BI Premium capacity. You discover that the dataset refresh fails after the refresh runs out of resources. What is a possible cause of the issue? A. Query folding is not occurring. B. You selected Only refresh complete periods. C. The data type of the column used to partition the data changed. D. A filter is missing on the report.

A The Power BI service partitions data based on date range. This is what enables only certain partitions to be refreshed incrementally. To make this work, the partition filter conditions are pushed down to the source system by including them in the queries. Using Power Query terminology, this is called "query folding". It is not recommended that incremental refresh is used when the required query folding cannot take place. Reference: https://powerbi.microsoft.com/en-us/blog/incremental-refresh-query-folding/

23 You build a report to help the sales team understand its performance and the drivers of sales. The team needs to have a single visualization to identify which factors affect success. Which type of visualization should you use? A. Key influences B. Funnel chart C. Q&A D. Line and clustered column chart

A The key influencers visual helps you understand the factors that drive a metric you're interested in. It analyzes your data, ranks the factors that matter, and displays them as key influencers. The key influencers visual is a great choice if you want to: See which factors affect the metric being analyzed. Contrast the relative importance of these factors. For example, do short-term contracts have more impact on churn than long-term contracts? Reference: https://docs.microsoft.com/en-us/power-bi/visuals/power-bi-visualization-influencers

102 You import two Microsoft Excel tables named Customer and Address into Power Query.

92 Case Study 2 - Contoso Ltd Overview Existing Environment Contoso, Ltd. is a manufacturing company that produces outdoor equipment Contoso has quarterly board meetings for which financial analysts manually prepare Microsoft Excel reports, including profit and loss statements for each of the company's four business units, a company balance sheet, and net income projections for the next quarter. Data and Sources Data for the reports comes from three sources. Detailed revenue, cost and expense data comes from an Azure SQL database. Summary balance sheet data comes from Microsoft Dynamics 365 Business Central. The balance sheet data is not related to the profit and loss results, other than they both relate to dates. Monthly revenue and expense projections for the next quarter come from a Microsoft SharePoint Online list. Quarterly projections relate to the profit and loss results by using the following shared dimensions: date, business unit, department, and product category. Net Income Projection Data Net income projection data is stored in a SharePoint Online list named Projections in the format shown in the following table. Revenue projections are set at the monthly level and summed to show projections for the quarter. Balance Sheet Data The balance sheet data is imported with final balances for each account per month in the format shown in the following table. There is always a row for each account for each month in the balance sheet data. Dynamics 365 Business Central Data Business Central contains a product catalog that shows how products roll up to product categories, which roll up to business units. Revenue data is provided at the date and product level. Expense data is provided at the date and department level. Business Issues Historically, it has taken two analysts a week to prepare the reports for the quarterly board meetings. Also, there is usually at least one issue each quarter where a value in a report is wrong because of a bad cell reference in an Excel formula. On occasion, there are conflicting results in the reports because the products and departments that roll up to each business unit are not defined consistently. Planned Changes Contoso plans to automate and standardize the quarterly reporting process by using Microsoft Power Bl. The company wants to how long it takes to populate reports to less than two days. The company wants to create common logic for business units, products, and departments to be used across all reports, including, but not limited, to the quarterly reporting for the board. Technical Requirements Contoso wants the reports and datasets refreshed with minimal manual effort The company wants to provide a single package of reports to the board that contains custom navigation and links to supplementary information. Maintenance, including manually updating data and access, must be minimized as much as possible. Security Requirements The reports must be made available to the board from powerbi.com. A mail-enabled security group will be used to share information with the board. The analysts responsible for each business unit must see all the data the board sees, except the profit and loss data, which must be restricted to only their business unit's data. The analysts must be able to build new reports from the dataset that contains the profit and loss data, but any reports that the analysts build must not be included in the quarterly reports for the board. The analysts must not be able to share the quarterly reports with anyone. Report Requirements You plan to relate the balance sheet to a standard date table in Power Bl in a many-to-one relationship based on the last day of the month. At least one of the balance sheet reports in the quarterly reporting package must show the ending balances for the quarter, as well as for the previous quarter. Projections must contain a column named RevenueProjection that contains the revenue projection amounts. A relationship must be created from Projections to a table named Date that contains the columns shown in the following table. The relationships between products and departments to business units must be consistent across all reports. The board must be able to get the following information from the quarterly reports: - Revenue trends over time - Ending balances for each account - A comparison of expenses versus projections by quarter - Changes in long-term liabilities from the previous quarter - A comparison of quarterly revenue versus the same quarter during the prior year Which two types of visualizations can be used in the balance sheet reports to meet the reporting goals? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point. A. a line chart that shows balances by quarter filtered to account categories that are long-term liabilities. B. a clustered column chart that shows balances by date (x-axis) and account category (legend) without filters. C. a clustered column chart that shows balances by quarter filtered to account categories that are long- term liabilities. D. a pie chart that shows balances by account category without filters. E. a ribbon chart that shows balances by quarter and accounts in the legend.

110 You publish a Microsoft Power BI dataset to powerbi.com. The dataset appends data from an on-premises Oracle database and an Azure SQL database by using one query. You have admin access to the workspace and permission to use an existing On-premises data gateway for which the Oracle data source is already configured. You need to ensure that the data is updated every morning. The solution must minimize configuration effort. Which two actions should you perform when you configure scheduled refresh? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point. A. Configure the dataset to use the existing On-premises data gateway. B. Deploy an On-premises data gateway in personal mode. C. Set the refresh frequency to Daily. D. Configure the dataset to use the personal gateway.

AC B: The on-premises data gateway acts as a bridge to provide quick and secure data transfer between on- premises data (data that isn't in the cloud) and several Microsoft cloud services. These cloud services include Power BI. On-premises data gateway (personal mode) allows one user to connect to sources, and can't be shared with others. An on-premises data gateway (personal mode) can be used only with Power BI. This gateway is well- suited to scenarios where you're the only person who creates reports, and you don't need to share any data sources with others. C: For Power BI users, refreshing data typically means importing data from the original data sources into a dataset, either based on a refresh schedule or on-demand. You can perform multiple dataset refreshes daily, which might be necessary if the underlying source data changes frequently. Incorrect Answers: A: On-premises data gateway allows multiple users to connect to multiple on-premises data sources. You can use an on-premises data gateway with all supported services, with a single gateway installation. This gateway is well-suited to complex scenarios with multiple people accessing multiple data sources. Reference: https://docs.microsoft.com/en-us/power-bi/connect-data/refresh-data

119 You have a line chart that shows the number of employees in a department over time. You need to see the total salary costs of the employees when you hover over a data point. What are two possible ways to achieve this goal? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point. A. Add a salary to the tooltips. B. Add a salary to the visual filters. C. Add salary to the drillthrough fields.

AC A: When a visualization is created, the default tooltip displays the data point's value and category. There are many instances when customizing the tooltip information is useful. Customizing tooltips provides additional context and information for users viewing the visual. Custom tooltips enable you to specify additional data points that display as part of the tooltip. B: Visual Filter applies to a single visual/tile on a report page. You can only see visual level filters selected visual on the report canvas. Incorrect Answers: C: With drill through in Power BI reports, you can create a page in your report that focuses on a specific entity such as a supplier, customer, or manufacturer. When your report readers use drill through, they right-click a data point in other report pages, and drill through to the focused page to get details that are filtered to that context. You can also create a button that drills through to details when they click it.

105 You have an Azure SQL database that contains sales transactions. The database is updated frequently. You need to generate reports from the data to detect fraudulent transactions. The data must be visible within five minutes of an update. How should you configure the data connection? A. Add a SQL statement. B. Set Data Connectivity mode to DirectQuery. C. Set the Command timeout in minutes setting. D. Set Data Connectivity mode to Import.

B With Power BI Desktop, when you connect to your data source, it's always possible to import a copy of the data into the Power BI Desktop. For some data sources, an alternative approach is available: connect directly to the data source using DirectQuery. DirectQuery: No data is imported or copied into Power BI Desktop. For relational sources, the selected tables and columns appear in the Fields list. For multi-dimensional sources like SAP Business Warehouse, the dimensions and measures of the selected cube appear in the Fields list. As you create or interact with a visualization, Power BI Desktop queries the underlying data source, so you're always viewing current data. Incorrect Answers: D: Import: The selected tables and columns are imported into Power BI Desktop. As you create or interact with a visualization, Power BI Desktop uses the imported data. To see underlying data changes since the initial import or the most recent refresh, you must refresh the data, which imports the full dataset again.

9 Case Study 2 - Contoso Ltd Overview Existing Environment Contoso, Ltd. is a manufacturing company that produces outdoor equipment Contoso has quarterly board meetings for which financial analysts manually prepare Microsoft Excel reports, including profit and loss statements for each of the company's four business units, a company balance sheet, and net income projections for the next quarter. Data and Sources Data for the reports comes from three sources. Detailed revenue, cost and expense data comes from an Azure SQL database. Summary balance sheet data comes from Microsoft Dynamics 365 Business Central. The balance sheet data is not related to the profit and loss results, other than they both relate to dates. Monthly revenue and expense projections for the next quarter come from a Microsoft SharePoint Online list. Quarterly projections relate to the profit and loss results by using the following shared dimensions: date, business unit, department, and product category. Net Income Projection Data Net income projection data is stored in a SharePoint Online list named Projections in the format shown in the following table. Revenue projections are set at the monthly level and summed to show projections for the quarter. Balance Sheet Data The balance sheet data is imported with final balances for each account per month in the format shown in the following table. There is always a row for each account for each month in the balance sheet data. Dynamics 365 Business Central Data Business Central contains a product catalog that shows how products roll up to product categories, which roll up to business units. Revenue data is provided at the date and product level. Expense data is provided at the date and department level. Business Issues Historically, it has taken two analysts a week to prepare the reports for the quarterly board meetings. Also, there is usually at least one issue each quarter where a value in a report is wrong because of a bad cell reference in an Excel formula. On occasion, there are conflicting results in the reports because the products and departments that roll up to each business unit are not defined consistently. Planned Changes Contoso plans to automate and standardize the quarterly reporting process by using Microsoft Power Bl. The company wants to how long it takes to populate reports to less than two days. The company wants to create common logic for business units, products, and departments to be used across all reports, including, but not limited, to the quarterly reporting for the board. Technical Requirements Contoso wants the reports and datasets refreshed with minimal manual effort The company wants to provide a single package of reports to the board that contains custom navigation and links to supplementary information. Maintenance, including manually updating data and access, must be minimized as much as possible. Security Requirements The reports must be made available to the board from powerbi.com. A mail-enabled security group will be used to share information with the board. The analysts responsible for each business unit must see all the data the board sees, except the profit and loss data, which must be restricted to only their business unit's data. The analysts must be able to build new reports from the dataset that contains the profit and loss data, but any reports that the analysts build must not be included in the quarterly reports for the board. The analysts must not be able to share the quarterly reports with anyone. Report Requirements You plan to relate the balance sheet to a standard date table in Power Bl in a many-to-one relationship based on the last day of the month. At least one of the balance sheet reports in the quarterly reporting package must show the ending balances for the quarter, as well as for the previous quarter. Projections must contain a column named RevenueProjection that contains the revenue projection amounts. A relationship must be created from Projections to a table named Date that contains the columns shown in the following table. The relationships between products and departments to business units must be consistent across all reports. The board must be able to get the following information from the quarterly reports: - Revenue trends over time - Ending balances for each account - A comparison of expenses versus projections by quarter - Changes in long-term liabilities from the previous quarter - A comparison of quarterly revenue versus the same quarter during the prior year Hotspot Question You need to calculate the last day of the month in the balance sheet data to ensure that you can relate the balance sheet data to the Date table.

27 You are configuring a Microsoft Power Bl data model to enable users to ask natural language questions by using Q&A. You have a table named Customer that has the following measure. Customer Count = DISTINCTCOUNT(Customer[CustomerID]) Users frequently refer to customers as subscribers. You need to ensure that the users can get a useful result for "subscriber count" by using Q&A. The solution must minimize the size of the model. What should you do? A. Add a description of "subscriber count" to the Customer Count measure. B. Set Summarize By to None for the CustomerlD column. C. Add a description of "Subscriber" to the Customer table. D. Add a synonym of "subscriber" to the Customer table. E. Add a synonym of "subscriberID" to the CustomerID column.

D You can add synonyms to tables and columns. Note: This step applies specifically to Q&A (and not to Power BI reports in general). Users often have a variety of terms they use to refer to the same thing, such as total sales, net sales, total net sales. You can add these synonyms to tables and columns in the Power BI model. This step applies specifically to Q&A (and not to Power BI reports in general). Users often have a variety of terms they use to refer to the same thing, such as total sales, net sales, total net sales. You can add these synonyms to tables and columns in the Power BI model.

107 You have sales data in a star schema that contains four tables named Sales, Customer, Date, and Product. The Sales table contains purchase and ship dates. Most often, you will use the purchase date to analyze the data, but you will analyze the data by both dates independently and together. You need to design an imported dataset to support the analysis. The solution must minimize the model size and the number of queries against the data source. Which data modeling design should you use? A. Use the Auto Date/Time functionality in Microsoft Power BI and do NOT import the Date table. B. Duplicate the Date query in Power Query and use active relationships between both Date tables. C. On the Date table, use a reference query in Power Query and create active relationships between Sales and both Date tables in the modeling view. D. Create an active relationship between Sales and Date for the purchase date and an inactive relationship for the ship date.

D Only one relationship can be active. Note: If you query two or more tables at the same time, when the data is loaded, Power BI Desktop attempts to find and create relationships for you. The relationship options Cardinality, Cross filter direction, and Make this relationship active are automatically set.

95 Case Study 1 - Litware, Inc. Overview Litware, Inc. is an online retailer that uses Microsoft Power Bl dashboards and reports. The company plans to leverage data from Microsoft SQL Server databases, Microsoft Excel files, text files, and several other data sources. Litware uses Azure Active Directory (Azure AD) to authenticate users. Existing Environment Sales Data Litware has online sales data that has the SQL schema shown in the following table. In the Date table, the dateid column has a format of yyyymmdd and the month column has a format of yyyymm. The week column in the Date table and the weekid column in the Weekly_Returns table have a format of yyyyww. The regionid column can be managed by only one sales manager. Data Concerns You are concerned with the quality and completeness of the sales data. You plan to verify the sales data for negative sales amounts. Reporting Requirements Litware identifies the following technical requirements: - Executives require a visual that shows sales by region. - Regional managers require a visual to analyze weekly sales and returns. - Sales managers must be able to see the sales data of their respective region only. - The sales managers require a visual to analyze sales performance versus sales targets. - The sale department requires reports that contain the number of sales transactions. - Users must be able to see the month in reports as shown in the following example: Feb 2020. - The customer service department requires a visual that can be filtered by both sales month and ship month independently. You need to create relationships to meet the reporting requirements of the customer service department. What should you create? A. an additional date table named ShipDate, a one-to-many relationship from Sales[sales_date_id] to Date[date_id], and a one-to-many relationship from Sales[sales_ship_date_id] to ShipDate [date_id] B. an additional date table named ShipDate, a many-to-many relationship from Sales[sales_date_id] to Date[date_id], and a many-to-many relationship from Sales[sales_ship_date_id] to ShipDate [date_id] C. a one-to-many relationship from Date[date_id] to Sales[sales_date_id] and another one-to-many relationship from Date [date_id] to Weekly_Returns[week_id] D. a one-to-many relationship from Sales[sales_date_id] to Date[date_id] and a one-to-many relationship from Sales[sales_ship_date_id] to Date[date_id] E. a one-to-many relationship from Date[date_id] to Sales[sales_date_id] and another one-to-many relationship from Date[date_id] to Sales[sales_ship_date_id]

E Scenario: The customer service department requires a visual that can be filtered by both sales month and ship month independently. Incorrect Answers: A, B: Just need two one-to-many relationships, no many-to-many relationships (with additional table) as a specific Sale occurs on a specific date. C: Cannot make a relation between a date_id and a week_id. D: The one-to-many relationships between the Sales and the Date tables goes in the other direction: for each date there can be many sales or shipments.

8 Case Study 2 - Contoso Ltd Overview Existing Environment Contoso, Ltd. is a manufacturing company that produces outdoor equipment Contoso has quarterly board meetings for which financial analysts manually prepare Microsoft Excel reports, including profit and loss statements for each of the company's four business units, a company balance sheet, and net income projections for the next quarter. Data and Sources Data for the reports comes from three sources. Detailed revenue, cost and expense data comes from an Azure SQL database. Summary balance sheet data comes from Microsoft Dynamics 365 Business Central. The balance sheet data is not related to the profit and loss results, other than they both relate to dates. Monthly revenue and expense projections for the next quarter come from a Microsoft SharePoint Online list. Quarterly projections relate to the profit and loss results by using the following shared dimensions: date, business unit, department, and product category. Net Income Projection Data Net income projection data is stored in a SharePoint Online list named Projections in the format shown in the following table. Revenue projections are set at the monthly level and summed to show projections for the quarter. Balance Sheet Data The balance sheet data is imported with final balances for each account per month in the format shown in the following table. There is always a row for each account for each month in the balance sheet data. Dynamics 365 Business Central Data Business Central contains a product catalog that shows how products roll up to product categories, which roll up to business units. Revenue data is provided at the date and product level. Expense data is provided at the date and department level. Business Issues Historically, it has taken two analysts a week to prepare the reports for the quarterly board meetings. Also, there is usually at least one issue each quarter where a value in a report is wrong because of a bad cell reference in an Excel formula. On occasion, there are conflicting results in the reports because the products and departments that roll up to each business unit are not defined consistently. Planned Changes Contoso plans to automate and standardize the quarterly reporting process by using Microsoft Power Bl. The company wants to how long it takes to populate reports to less than two days. The company wants to create common logic for business units, products, and departments to be used across all reports, including, but not limited, to the quarterly reporting for the board. Technical Requirements Contoso wants the reports and datasets refreshed with minimal manual effort The company wants to provide a single package of reports to the board that contains custom navigation and links to supplementary information. Maintenance, including manually updating data and access, must be minimized as much as possible. Security Requirements The reports must be made available to the board from powerbi.com. A mail-enabled security group will be used to share information with the board. The analysts responsible for each business unit must see all the data the board sees, except the profit and loss data, which must be restricted to only their business unit's data. The analysts must be able to build new reports from the dataset that contains the profit and loss data, but any reports that the analysts build must not be included in the quarterly reports for the board. The analysts must not be able to share the quarterly reports with anyone. Report Requirements You plan to relate the balance sheet to a standard date table in Power Bl in a many-to-one relationship based on the last day of the month. At least one of the balance sheet reports in the quarterly reporting package must show the ending balances for the quarter, as well as for the previous quarter. Projections must contain a column named RevenueProjection that contains the revenue projection amounts. A relationship must be created from Projections to a table named Date that contains the columns shown in the following table. The relationships between products and departments to business units must be consistent across all reports. The board must be able to get the following information from the quarterly reports: - Revenue trends over time - Ending balances for each account - A comparison of expenses versus projections by quarter - Changes in long-term liabilities from the previous quarter - A comparison of quarterly revenue versus the same quarter during the prior year Drag and Drop Question You need to create a DAX measure in the data model that only allows users to see projections at the appropriate levels of granularity. How should you complete the measure? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point. Select and Place:

Scenario: Revenue projections are set at the monthly level and summed to show projections for the quarter. Box 1: IF Box 2: ISFILTERED ISFILTERED returns TRUE when columnName is being filtered directly. If there is no filter on the column or if the filtering happens because a different column in the same table or in a related table is being filtered then the function returns FALSE. Box 3: SUM Reference: https://docs.microsoft.com/en-us/dax/isfiltered-function-dax
