Today I issued two lot controlled items to an indirect Work Order (WO-G). The WO was made in our main inventory location. The parts were in our Returns location. In WO-G I changed the location and the items were issued from the Returns location, as expected. However, the Lot number (I used the look up to select the Lot number from the Returns location) was driven negative in the main stock location and left positive in the Returns location.

Does the same for Serial numbers.
