Diagnosis
The set operation you specified could not be performed because one ofthe versions involved in a previous set operation has been editedincorrectly. The version that created the error is listed in brackets.

System Response
If you perform several set operations sequentially, the system checksfor each set operation whether the relevant versions have already beenincluded in previous set operations. If you wanted to change one of thetwo versions in a previous set operation but these changes were notsuccessful, the system no longer carries out further set operations forthis version.

Procedure
Check why the previous set operation could not be carried out. Ifnecessary, correct the error and perform the set operations again.
