Creating application overlays

Version:

Define the extent to which business users can change your decisioning application by creating an application overlay. Specify the application, revision ruleset, and access group for the overlay.

You create an application overlay in the Create New Application Overlay wizard.
  1. In the header of Dev Studio, click Configure Decisioning Infrastructure Revision Management Application Overlays .

  2. Click New.

  3. In the Create New Application Overlay wizard, click Create.

  4. Provide the following application overlay details:

    1. In the Name field, provide the unique name of the application overlay.

      By default, this field is populated with the enterprise application name.
    2. In the Description field, provide a meaningful description or additional details for the application overlay.

    3. In the Revision ruleset field, specify the name of the revision ruleset.

  5. Click Next.

  6. Edit the default list of access groups for the application overlay:

    • To edit the name or the associated privileges of an access group, click the access group name.
    • To add an access group to the overlay, click New Access Group.
    The default access groups have access to the Pega Marketing or Customer Decision Hub portals. The following default access groups are available:
    Revision Manager

    Initiates a change to the application by creating a revision and the associated change requests. The revision manager approves change requests, submits completed revisions, and deploys revision packages.

    Strategy Designer

    Amends the business rules that are part of the change request and creates rules. When the changes are complete, the strategy designer tests the changes by running test flows and simulations, and, if the results are satisfactory, submits the changes to the revision manager for approval.

    <overlay_name>FastTrackRevisionManager
    Initiates and resolves fast-track change requests.
    <overlay_name>FastTrackStrategyDesigner
    Amends or creates business rules as part of a fast-track change request, in the context of a production application and in isolation from standard revision management process.

    For more information, see the following articles on Community:

    • Release urgent business rule updates through fast track change requests
    • Resolving fast-track change requests
  7. Click Next.

  8. Define the list of rules that are available for revision management:

    1. Select the rule instances that you want business users to change.

    2. Click Include for revision management.

    For more information, see Rules supported in Revision Management on Pega Community.
  9. Click Next.

  10. Review the application overlay settings, and then click Create.

When the overlay creation is complete, you can export a RAP file that contains the application overlay and all operator accounts for deployment in other environments.

  • Addressing changing business requirements

    With revision management, business users can respond to changing requirements by modifying and deploying your application&rsquo;s rules in a controlled manner.

  • Application overlays

    Application overlay is an application that is built on top of a decision management enterprise application. An application overlay defines the scope in which business users can change the application (for example, by managing propositions, modifying business rules, or running simulations) to adjust the application to constantly changing business conditions and requirements. System architects use the Create New Application Overlay wizard to define the application overlay components, such as the revision ruleset or revision records:

  • Editing application overlays

    You can edit an existing application overlay to modify its application definition as well as the set of rules that are available for revision management.

  • Deleting application overlays

    You can delete all application overlays except the direct deployment application overlay. When you delete an application overlay, all revision records are deleted, except for the application overlay's revision ruleset. The revision ruleset is also not deleted from the enterprise application ruleset.
