Diagnosis
You attempted to make an entry with transaction &V1&. This is notpossibe as the transaction is not a real transaction.
You can determine whether it is a real transaction as follows:

• If the transaction is assigned to an internal transaction, the entry is
determined from the table of internal transactions.

• If it is an item from a budget billing plan, the check takes place
against the table TEABSTVOR (only IS-U).

• If it is an external transaction, the check takes place against the
entries in the view 'Attributes per Company Code and Division'.

Procedure
Change the entry appropriately.
