Document check and free entry in financial document are contradictory!

What causes this issue?

You tried to activate the check of &V1& in the document against the
check of &V1& from the financial document. At the same time, you allow
the free entry of &V1& in the financial document. This switches off the
check against the respective value table.

How can this happen?

Enter the Incoterm 'EX' ('Ex Works') as free entry of Incoterms in the
financial document. The value check in the document only allows the
correct entry of 'EXW' for 'Ex Works'.
If you now assign the financial document to this document, the
Incoterms check of the financial document and the above document would
always block the last one because the Incoterms are different.
