Thanks Raymond
My purpose is to get the same ADRNR of the vendor but uses International version (ADRC-NATION = 'I') instead of default version done by the standard (ADRC-NATION = ' ')
And I think it should create a new address every time a PO is created, so at ME_PROCESS_PO_CUST I won't have the new address number to assign to MEPOHEADER-ADRNR .
