Currently, when a Batch or Serial Number has a Use By/Sell By date which has expired and you allocate/issue this stock to a Works Order,Sage warns you that the stock is out of date but still allows you to proceed. Ideally,there should be a setting, or additional validation step whichprevents the allocation/issue because the stock is out of date. The end user could then switch this settingon/off depending on their requirements and if the out of date stock can still be used or must be written off.
