You are not able to create or update an application overlay.

Cause

When you create or update an application overlay in Designer Studio, the rules that you select for revision management are saved into a new version of the application ruleset. Rules that are part of the application overlay might have been modified (edited or deleted from your application). Edits to the rules might cause compilation issues depending on the rule types that were included in the application overlay. For example, a data flow in the change request might reference a rule instance that was deleted.

Error in an application overlay

Solution

These steps are usually done by a system architect.

1. In Designer Studio, open the rule instances that caused the error to determine whether they might have been deleted.

2. In the rule forms, click Check out and Save.

3. Investigate error messages or compilation issues and fix them.

4. If you still see errors or have other issues, save the rules into a new version of the application ruleset.

   Sometimes, saving the rules into a new version of the application ruleset will resolve issues that you have when adding the rules to an application overlay.
