You can check or compare your current data of your items in PIER using the Query function.
For this, you will need your GTINs with linked LOT numbers to them.
1. Go to the section Query.
2. Enter your GTIN and the LOT.
3. If your Query is successful, PIER will show you which data of your items exists in PIER. We recommend to check it before labelling process to ensure that data in the system is the same to the one which will be on the label.
If your Query is unsuccessful and you could not find your GTIN and LOT Combination please refer to the article How to add new articles in PIER? or send your request at pier@sourcingsupport.de
