The purpose of this function is to setup a cross reference between the vendor’s product barcode label and your own company’s product.

To add a cross reference click "Add Reference".
Then you can type in the vendor’s product barcode number, but it’s much faster to just click on the barcode number box and scan the barcode.
Now select your own company’s product code that you want to reference.
Press "Submit".

Now you have added a cross reference!
