The CUA &V3& has not been activated in this child system (&V1&).

If you actually want to move the child system &V1& from the CUA &V2& to

by calling the report RSDELCUA locally in the child system &V1&
(deletion option: Invalid Content in CUA Tables).

01672 - Details

• The SAP error message 01672 indicates that the child system you are trying to add to a Central User Administration (CUA) is already part of another CUA. This situation arises when you attempt to include a child system in a CUA configuration, but that child system is already associated with a different CUA.
