In some manufacturing scenarios, when finished goods don't meet quality parameters, the finished good can be corrected by adding it to the raw materials consumed in a new production of the same item. Currently, NAV/BC doesn't allow a an item to be the output and the consumption. This is a good safety net for planning purposes, but makes re-work difficult.

Examples include:

Medical device manufacturer - produces diabetes testing pack which includes a machine and testing strips that expire. When the testing strips expire, the manufacturer can rework the finished good by consuming it and another set of testing strips to make the same finished good.

Chemical and food manufacturers - Produce product that is slightly out of spec but can be added to the next batch to bring the product back into spec.
