partially received/partially invoiced PO how can we close

Hi,

Business took PO Status report... Some PO's lines are partially received/partially invoiced. And The remaining quantity will not come. So we think that we have options about close the PO line or cancel the PO line.

but after we cancel the PO line, we can not see that lines on Purchasing screen. And purchasing summary - lines / we see that PO line is cancelled status. Yes if we looked at shipments we see the Quantity 700 / Quantity received 650 / Quantity billed 650 / Cancelled 50

Is this normal?

Or when I calcel the partially received PO lines, systems create a new shipment line. 1 and 2 / shipment line 1 -- 650 is received / shipment line 2 -- 50?
