Reproducing the Issue


  • You have created a custom screen scenario.

To Reproduce:

  1. Open your custom work center.
  2. Open the custom view.
  3. Open any instance in the OWL on the custom view.
  4. Click Edit.
  5. Make a change in any field and click save.
  6. Observe the message / behavior.

Message: No changes detected; Save not executed.

Behavior: Data is not saved in fields.


You have configured your screen so that changes to these fields are not considered as an edit to the instance. The responsible property is Work Protect Relevant. If this property is set to "False", then any change in these fields will not be considered during the final Window-Close check during the Save action.


You need to re-model your data model elements and set Work Protect Relevant property set to "True":

  1. Open the data model of the UI Component and select a data model element.
  2. In the Properties window, you will see the Work Protect Relevant property.
