Allow posted quantity (P/Qty) to be entered on the Inventory Order (IO) without entering the received quantity (R/Qty)

Request to allow the P/Qty to be filled in without having to fill in the R/Qty

Original User Story:

When doing weekly invoicing and we are in an IO if we have not received the part yet but are being invoiced for it, we currently have to change the R/Qty to what ever we ordered them our P/Qty then go back and put the R/Qty back to 0.

Because we are all human and sometimes forget, this puts our inventory out. Would you be able to make it so we don't have to put a R/Qty in order to fill in the P/Qty so we know 100% that it is not here.

This would be so very helpful.
