Environment
SAP S/4HANA Cloud
Cause
The error shows up because you maintain the activity text as "No Activity" in the corresponding work center.
After changing the activity text type, the error will be eliminated.
This issue happens when you confirm the operation with correct settings and then change it incorrectly before cancelling the confirmation.
Resolution
Maintain the correct settings for the activity in the work center.
