Suitable PO Action as per business

Hi all.

Let me to state the business first:

We make PO & perform procure to pay cycle accordingly. (1) Some times we reject partial quantity (e.g. 50%) & close the business with respective supplier on a specific PO. (2) Usually we get outstanding POs with meaningless un-received quantity (i.e. fractional, e.g. some grms out of hundreds of KGS).

Here we have to close both types of PO.

Now please suggest best action (e.g. Cancel, Closed, Finally Closed, etc.) for each scenario.

Regards,

Abdul Rehman.
