@Chris Forgione 1. if you set your picking preferences to FIFO, FEFO, or receipt date the system will choose lot by the received date in the order designated.
2. depending on if you have NS WMS, rf smart, or perhaps advanced manufacturing you can direct production staging pick tasks in the same manner. there are several ways to automate fully or not at all this process. the purpose being to eliminate the need for a material handler to choose a lot number.
