You can use different UPCs per channel for the same product. This feature is disabled by default so must be activated:
- Select the client setting Enable UPC for Channel.
- On each channel properties page, see the UPC for Channel field. Here, you can enter a different value than the UPC on the Main Product Properties page. When posting products to that channel, this UPC will be prioritized and sent.
- By default, this field will use the current UPC from the Product Summary page.
