"PO could not be changed using the Enjoy-BAPI"

[kowong]

Dear Expert,

I am having this problem using BAPI_PO_CHANGE,

I want to set invoice final indicator.

i_poitem-po_item = i_process-ebelp .

i_poitem-final_inv = 'X' .

APPEND i_poitem .

i_poitemx-po_item = i_process-ebelp .

i_poitemx-final_inv = 'X' .

APPEND i_poitemx .

CALL FUNCTION 'BAPI_PO_CHANGE'

EXPORTING

purchaseorder = i_process-ebeln

TABLES

return = i_return

poitem = i_poitem

poitemx = i_poitemx.

for some POs, it returned :

"PO could not be changed using the Enjoy-BAPI".

When I use ME22N to do that, it does work....

Thank you ...
