3108808 - UI Rules and Validations not available for custom screen


You would like to make use of UI Rules and Validations while adapting a custom screen.


  • SAP Cloud for Customer
  • SAP Cloud Applications Studio

Reproducing the Issue


    • You have created an add-on on the Studio.
    • You have created a custom BO.
    • You have created custom screens or an EC.
    • You have created the required extensibility anchors for the UI components.

Reproducing the issue:

  1. Navigate to the custom screen.
  2. Start Adaptation mode.
  3. The option to create the rule is missing.


UI rules are not supported to be created via adaptation mode for any custom screen.


One possible workaround is to create a Calculation Rule to control the field behavior on the UI Designer.
