3131688 - Unpublished changes cannot be undone on Custom CDS with "External API" scenario


On draft versions of Custom CDS views with "External API" scenario, it is not possible to revert changes in case a communication scenario exists.


  • S/4HANA
  • S/4HANA Cloud

Reproducing the Issue

  1. In app "Custom CDS views", edit a custom CDS with "External API" scenario which is dependent on a Custom Communication Scenario.
  2. Add a new element or calculated field.
  3. Once added, the element cannot be removed or the calculation edited.


Once a Custom CDS View is used, no incompatible changes are allowed. In the case of "External API" scenario, this is also not possible on Drafts.


In order to revert the changes, the draft needs to be discarded completely, or the dependency to the Custom Communication Scenario removed.
