PO Change: Cencel PO lines in iProcurement creates multiple PO revisions.

Hi PO Experts,

   PO Change: Cencel PO lines in iProcurement creates multiple PO revisions. PO revision incremented by 1 for each line cancelled.

Is this normal? Do you have any standard document to back this us? I searched for 2 days and found nothing specific to this behavior.

    The problem is when my user cancel multiple PO lines in iProcurement in one single time. The system creates multiple numbers of revisions for it depends on how many lines are cancelled.

When viewing PO voucher, it will show only the last revision. I mean the last line that is cancelled and the remaining active lines.
