Update country codes for foreign trade

Question: Hi all !

I am updating our SAP Systems with all new Country Codes (ISO-Alpha-2) for foreign trade statistics (and preference calculation).

For example Monaco was a unique code "MC" with key "001" (same key of France). Now I have to change this code "MC" to "FR", but I can create only one key "FR" into SAP. So I've just modified the "ISO-Code" field with "FR".

What do you think about this ? Is this modification OK ? Thanks for your support !

Greets,
David
