As per metalink,
PO_DOCUMENT_UPDATE_GRP - R12
po_change_api1_s - 11i
It is suggested to use PO_DOCUMENT_UPDATE_GRP
Thank you for the prompt response.
I can see that
1. Note 1078842.1 refers to PO_CHANGE_API1_S.update_po and Release 11.5 to 12.2
2. While Note 1406047.1 refers to PO_DOCUMENT_UPDATE_GRP and Release 11.5 to 12.1
Are these the notes you were referring to if so isn't PO_CHANGE_API1_S.update_po is more close to 12.2.5 release?
