Occasionally, a user will post consumption on a production order and then realize they made a mistake. They can post negative consumption to undo the erroneous consumption, but NAV/BC does not allow them to finish or delete the production order because there is no output. The work around is to post output for a quantity of 1 and then do a negative adjustment on the item journal. We would like an option to close a production order if the net consumption is zero, or to "undo" the entire production order (similar undo shipments on sales shipments).
