Technical background: The system searched the log tables USZBVSYS in
the central system for the user &V1& in &V2&, where the states "A"
(system call for deletetion started), "D" (system assignment of the
user deleted) and "X" (to be deleted) are not accepted.

How to fix this error?

Specify an existing substituted user.
If you believe that the substituted user &V1& must exist in logical

central system to the child system, to obtain a correct entry in the
log table USZBVSYS. You can then repeat the classification as
