Company code & and CO area & have different currencies

What causes this issue?

Company code &V1& is recorded in &V3&, and controlling area &V2& is
recorded in &V4&.

System Response

This is not allowed since exchange rate fluctuations between postings
to CO and settlements from CO lead to an unacceptable value added.

How to fix this error?

Check whether the assignment between company code &V1& and controlling
area &V2& is intended.
Assign the same currency to company &V2& as controlling area &V1& with
the configuration functions.
