Use CRS Serial/Lot Number Entry to enter serial/lot items for return provided the items are a valid in the serial/lot file. If you attempt to enter a serial/lot number that is not on file, the system displays the message: Serial Number must be in Serial/Lot file to return.
You can still enter the CRS without entering the serial/lot number, but that line will not be converted to a Credit Memo until the number is entered. If you are returning to another warehouse, then you will have to add the serial/lot number in Serial/Lot F/M.
