To add an individual ID to your purchase order and your goods, you have to activate the column "Carton Note" in your purchase order.
You can use the function together with placeholders so that the note is displayed on the shipping labels or in the email table overview.
Note that these notes only apply to the box in the specific supplier order - not to all boxes with this SKU.
This way you can assign different item numbers depending on the order.
Step 1) To do that, go to the "Warehouse Manager" menu and click on "Settings".
Step 2) Click on "Manage" on the e-mail settings box (1) and here you can either edit the existing templates or make a new one (2).
Step 3) You can add carton notes to shipment labels and to e-mail tables.
