The trading partner entered in account & & is not valid

What causes this issue?

You have entered a cross-company code transaction. The system should
now automatically generate a clearing posting for account &V1& in
company code &V2&. The system determines the trading partner for this
line item from the company code to which the clearing posting is made.
This trading partner must be the same as that in the account master
record.

System Response

The system does not carry out the posting.

How to fix this error?

Change the master record of the account in question. Adjust the trading
partner entered there accordingly.
