PO closing

Hi,

We have a scenario where we would like to close partially received PO through the delivered PO Close process. But the PO's are not getting picked for closing.

Replication Steps:

1. Created a PO for 10 qty @ unit price of 500.

2. Dispatched the PO

3. Received 5Qty by copying the PO

4. Created a voucher by copying the receipt of 5Qty

5. Run matching for the voucher and post the voucher

6. Now when running closing process (just by selecting one PO), the PO close process is not closing the partially received PO.

is there anything that is missed ?

Thanks,
