3361534 - C4C Cloud For Customer - Change Transaction - How Many can be Created?


Each time a change is made on the Tenant Layout, this will Create a corresponding 'Change Transaction'.

After 1000 CTs are made, Performance issues and other bugs may occur (Check See Also).

After 5000 CTs are made, the system will not save further changes, as this is a limit set by development.

Reproducing the Issue

  1. Open the Adaptation Mode.
  2. Perform any change (Ex: Hide a field).
  3. Click on 'End Adaptation'.
  4. Change is not saved or an error is shown.


This is the expected system behavior.


You need to delete the unwanted CT's. Once this is completed, the errors will not occur.
