Purchase Order - change Foreign Trade Export/Import (EIPO)

Hi,

Is there a way to programatically change Purchase Order - Foreign Trade Export/Import data (table EIPO)?

The function BAPI_PO_CHANGE has a parameter for it (POEXPIMPITEM), but documentation states that this data cannot be changed. I tried just in case - it doesn't work.

Is there some other function / class-method / Business Object or something? If nothing better exists, I am tempted to try CALL TRANSACTION with BDC data on ME22 or ME22N.

Any experiences?

Thanks!

KR,

Igor
