Epicor Serial Numbers and Bartender Labels

Does anyone have clear instruction on getting Bartender to print labels with the Epicor Serial Numbers included? I have a Data Directive that sends a .bt file to a scanned folder whenever we have a MFG-STK transaction, which prints a product label. However, I haven’t been able to figure out how to get the serial number added to that label.

Looks like you could join in the Erp.PartTranSNTran table with the PartTran linking with PartTran.TranNum = PartTranTranNum (+ company = company) and that should get you the SerialNumber for your bt file.

I have tried that with no success. Have you had success with that?
