Return to vendor for account assignment types C, K and F

[mike_rupp]

We're using basic SAP ECC Purchasing with Quality Inspection Lots.
The issue we are having is how to do a return to vendor if the inspection lot fails and the account assignment category in the purchase order is (C: sales order), (K: cost center) or (F: order). 

We have no problem if the account assignment category is (blank: general stock) or (E: sales order stock).   In these cases, the received material goes into Quality Inspection Stock.  If the inspection passes, then an "Acceptance" usage decision moves the material into the appropriate stock segment for use.  If the inspection fails then a "Rejection" usage decision moves it into Blocked stock in a "Return to Vendor" storage location.  From there we process a 122 movement type to send it back to the vendor which also re-opens the purchase order line item.

The problem with (C, K & F) is that it puts nothing in stock.  If the inspection fails, we don't seem to have any way to send the failed material back and re-open the purchasing line item.
