Was verursacht dieses Problem?

Customer record &V1& is to be renamed to &V2&. Customer record &V2&
exists in the system, but is not entered as <ZK>old value</> in the
mapping table. This would lead to an
<DS:TX.CNV_MBT_IMPLICIT_MERGE>implicit merge</>. This is not allowed.

Wie behebe ich diesen Fehler?

If you want to merge &V1& and &V2& to &V2&, enter &V2&, as <ZK>old
value</> and as <ZK>new value</> in the mapping table and set the
priority flag accordingly. You can set the priority flag either for &V1&
or for &V2& .
If you do not want to merge &V1& and &V2&, you can:
Enter a value that does not exist in the master data table for new
<ZK>value</>
Or
Include &V2& also as <ZK>old value</> in the mapping table and enter a
different value for <ZK>new value</>.
