source system, but it already exists in the target system (or there is
an entry in the table TADIR).
If the technical attributes of this object are not identical in the two
systems, the client cannot be copied.

How to fix this error?

If there are differences, transport the DDIC object with the transport
tools. Use the customizing transport with which the object was created,
or create a 'Transport of copies' with 'R3TR object type object name'.
The object type is DOMA for domains, DETL for data elements, TABL for
tables and VIEW for views.
