Is there any way to update (add new lines only) existing PO through API in Oracle 11i...? In order to update any information in existing PO, we are using "PO_CHANGE_API1_S.UPDATE_PO" API. we've already developed our concurrent program. But we are unable to insert new lines in the existing PO through program. Please let us know the way out if any or suggest us how can we do the same.
