Rules determining what can be changed on a Requisition in iProcurement

Hi,

I have a question about using iProc on R12.1.3.

I have been testing changing REQs linked to POs in iProc, and where there is either no invoice matched to the PO, or if the invoice is matched, it's on hold and not validated.

I can see on the PO_REQUISITION_LINES_ALL table, that the REQ Line Type is determined by the LINE_TYPE_ID

From what I can see:

•    If the LINE_TYPE_ID is 1020, that corresponds to a line type of "Goods or services billed by amount" - and only the QTY can be amended on the REQ
