David:
I just gave it a shot - and it works!

I do not know if I was aware in the past about the clicking the right-mouse button & selecting the option to Complete.
But I am pleased that you provided me with a simple & quick solution.


I would guess that we can use this option on truly open orders that are partially filled.
Should the situation change later in that no more Items will be received from that PO, we can simply close the PO using the right-button and selecting Close.

Thank you David!
