Cancelling Purchase order lines.

 Hello all,

      When I open an approved Purchase order to cancel a number of lines the PO revision changes after I cancel each line. So if I cancel 3 lines in the one session the PO revision goes to 3. Is this standard functionality ? I'm on R12.0.6.

  If I add a note to supplier to 3 lines on the approved PO the revision does not change until I save my edits and it goes to revision 1.

 

Regards
