Diagnosis
An incompatible change was made to the source of the data transferprocess (DTP) and the error stack for the DTP contains data. Versionstherefore need to be defined for the error stack. However, this is notpermitted because any existing requests in the error stack are notincluded when filtering new records with the same key.

System Response
The DTP cannot be activated.

Procedure
Empty the error stack before the incompatible change. You have twooptions:

• Delete the requests that resulted in records containing errors.


• Update the data for the error stack with an error DTP.

Note however, that any errors that still exist may be updatedback into the error stack.
