Product unit's quantity is different from feeder list unit quantity

2.  For this route they actually is using ISN(first side Serialized) to Lot(Second side panel ID), yet, the file has already wrong during laser marking process. If the route is ISN to Lot, the laser mark file should have both side SN, but the file user transferred only consists of one side without the panel ID (Please check the laser mark program).

3. So, when user is doing transaction at Lot route step, MES will be using panel ID to do the transaction, and because of during laser marking the file don't have panel ID. Hence, it caused the system failed to find the relationship for that panel.

4. Therefore, if user wants to transact using SN in ISN to LOT route, user is required to have the panel ID that allows system to find out the relationship between panel and each cavities to be able to get the SN under that panel. 

5. This is an example of a wrong Laser Mark File as there is no panel ID.

6. The following is the correct Laser Mark File.

7. If there is no panel ID stated inside the Laser Mark File, an Auto Generated Lot Number will be created where it will act as the panel ID and it is not physically exist. Hence, in this case user can use one of the SN to search at Unit History page to find the Auto generated Lot number to do the transaction manually at PTI screen but not via ATE because the panel ID doesn't exist.

8. After user has entered the lot number and click 'Add' button to proceed, user may click on the 'Show Grid' button to see all the SN that belong to the panel. If everything is good, user can click on 'Pass' button to complete the transaction.
