What causes this issue?

You tried to change the company code assignment or the currency of the

code (&V3&) and the program position (&V1&) are different. This is not
allowed.

System Response

The change is not allowed.

How to fix this error?

If you assign a company code to a program position, and the company
code currency is the same as the controlling area currency, then you
can choose any currency for the program position.
If, on the other hand, you assign a company code to the program
position, and this company code has a different currency than the
controlling area currency, then you can only choose either the
controlling area currency or the company code currency for the program
position.
