An Order fulfillment process includes a request for quotes from multiple shippers. You want the system to automatically call a quote request subprocess for each vendor. How do you configure your process? * Add a Subprocess shape for the request subprocess and specify the Spinoff option. * Add a Split Join shape and run the request subprocess for each vendor on a page list. * Add a Split For Each step to the case life cycle and run the subprocess for each vendor on a page list. * Add a Split For Each shape and run the request subprocess for each vendor on a page list.

* Add a Split For Each shape and run the request subprocess for each vendor on a page list. The Split For Each shape runs a subprocess for each item on a page list.

In a Prepare job offer process, you configure a Split For Each shape. The shape runs a compensation approval subprocess to a list containing four managers. The prepare job offer process resumes as soon as one manager completes the approval process. Which join condition in the Split For Each shape supports this requirement? * A Some join condition * An Iterate join condition * An All join condition * An Any join condition

* An Any join condition This condition resumes the main flow when only one of the subprocesses completes.

How do you add the Split Join shape to your process?

Which type of parallel processing shape do you use to start an interview process based on a list of employees who must separately interview a job candidate? * Subprocess shape * Subprocess shape with the spinoff option enabled * Split For Each shape * Split Join shape

* Split For Each shape A Split For Each shape allows you to iterate over a list of employees to start an interview process for each employee. The other options are wrong, since: A Split Join shape allows you to call multiple different, independent processes. The spinoff option in the Subprocess shape allows you to run the subprocess in parallel with the main flow. The subprocess shape without the Spinoff option enabled does not support parallel processing.

For the Split join, what are the options on the Subprocess tab, configure the context of the subprocess?

Does a parallel subprocess run in sync or run asynchronously?

Each subprocess runs asynchronously and in parallel.

What shapes does Pega have for more complex parallel processing?

For more complex parallel processing requirements, Pega provides the Split Join shape, the Split For Each shape, and the spinoff option in the Subprocess shape.

What is a consequence of running in parallel?

However, concurrent access may result in a need to refresh the assignment due to the fact that another user can make changes at the same time

In the Join list field of the Split for Each shape, what is the impact of selecting "All" or "Any" to define when the parent process resumes processing?

If you select Iterate and your process resumes after a specified when condition evaluates to true, in the Exit iteration when field, enter a name of the when condition that resumes processing after evaluating to true. If you select Some and your process resumes after a specified number of subprocesses is complete, configure the conditions to resume processing:

How do you select between a series of actions or a series of forms to be completed in the parallel flow after the Split for Each shape?

In the Filter flow by field, select the subprocess category: * To start a subprocess that is a series of actions to complete, select Process flow. * To start a subprocess that is a series of forms to complete, select Screen flow. In the Flow name field, enter the name of the subprocess that you want to run. Optional: To control whether the flow runs for all or some pages in the page property, in the When field, enter a when condition that evaluates values in each page. At run time, the system evaluates this when condition rule once for each page of the property in the Page Property field and starts a subprocess for any page for which this rule evaluates to true.

How do you complete the Join list for the Split for Each shape?

In the Join list, define when the parent process resumes processing: * To resume processing after all subprocesses are complete, select All. * To resume processing after any subprocesses are complete, select Any. After any of the subprocesses are complete, processing of the remaining subprocesses stops and the system cancels open assignments. * To begin processing of individual pages for which a specified when condition evaluates to true, select Iterate. * To resume processing after a specified number of subprocesses is complete, select Some. In the Page property field, enter the Page List or Page Group property that is the basis of the split.

What is the impact of parallel processing on locking?

Review the locking strategy and consider switching to the multiple user locking strategy. If concurrent access occurs, a user might need to refresh the assignment if another user makes changes at the same time. Learn more about case locking later in the mission.

What actions do you select the Join list for a Split join to resume processing after all subprocesses are complete?

Select All.

What actions do you select the Join list for a Split join to resume processing after any of the subprocesses is complete?

Why would you run multiple instances of the same subprocess with a Split for Each shape?

Speed up case resolution by creating multiple instances of one subprocess that users can work on simultaneously and that later rejoin the parent process.

Which parallel processing type do you use when you need to run a subprocess multiple times to iterate over the pages of a Page List or Page Group property.

Spilt for Each

Which parallel processing type do you use when you need to create a subprocess in your case, that runs independently of the main workflow, whereby the case can continue without waiting for this subprocess to complete?

Spinoff (Note - "case can continue without waiting")

Which parallel processing type do you use when you have two (or more) subprocesses that proceed independently and in parallel?

Split join

How are join conditions used in a split join?

The Split Join shape gives you the flexibility to use join conditions that determine when the primary process can continue. For instance, a Split Join may include three separate approval subprocesses. You can specify that only two of the three approvals must be completed before resuming the main flow.

What is a Join Condition in a Split Join?

The join condition may iterate over a when condition or a count to determine when to resume the flow.

What is a key prerequisite before selecting to use parallel processing?

The prerequisite for this process to work safely is to review the locking strategy, and consider switching to the multiple user locking strategy.

What is the "main process" in parallel processing?

The process to which you add the shape is called the main process.

What does the "main process" do in parallel processing?

The shapes call one or more subprocesses that proceed in parallel.

What is a Spinoff?

The spinoff option in the Subprocess shape allows you to run the subprocess in parallel with the main flow.

How do you add a Spinoff shape?

The spinoff option is an advanced feature in the Subprocess shape and is accessed in the flow diagram.

Why have parallel processing?

This configuration allows users to perform tasks independently to complete the work in a stage

How would you send a Case for approval after the Split for Each shape?

This is done by selecting a suitable Page List or Page Group property that is the basis of the split into Page property field. To send a case for approval to multiple approvers, enter a page property that stores pages with the details of the approvers. The result is the system autopopulates the Class field that stores the class with embedded pages of the property that you provide.

When configuring the Split for Each shape, how do you add a link to the subprocess in the breadcrumb trail navigation?

To provide a link to the subprocess in the breadcrumb trail navigation, select the Enable navigation link check box, and then configure additional navigation options:

When is a Split Join suitable?

When the sub-processes are unrelated and can be performed in subprocesses that proceed independently and in parallel.

What is the main difference between a Spinoff and other parallel processing shapes?

With the spinoff option in the Subprocess shape, the main process does not wait for the subprocess to complete before proceeding. The subprocess does not rejoin the main process.

If you select to define a Join list for the Split for Each shape, can you define the order in which the system evaluates the pages?

Yes. In the Page group iteration settings section, define exact values to evaluate at run time: * In the Subscript order field, enter text that your process compares with the subscript value for each page in the group. For example, to find pages that include the word Pega, enter Pega. * Optionally, to require an exact match, select the Exact match check box. For example, to find pages that include an email address of the Pega domain, enter @pega.com. * Another option is to ignore the pages in the group that do not match the subscript order that you provide, clear the Process remaining changes check box. Otherwise, your process evaluates the pages without a match after processing all conditions in the Page group iteration settings section.

Can you use a join condition on a Split For each?

Yes. Like the Split Join, you can use a join condition to control when the primary process resumes. If you use an iterate join condition, you can start flows for elements of the Page Group or Page List property one by one, and configure testing conditions to determine whether to continue.

How can you use a Split For Each shape?

You can use a Split For Each to iterate over a list of vendors and send a quote request from each vendor on the list.
