Why this issue is happening
You are seeing this issue because one or more of your product IDs are already used. Specifically, a multi-channel product targeting marketing methods for physical stores conflicts with a local-only product. This conflict occurs because both share the same product ID, content language, and feed label.
Common reasons for Product ID already used
- A local-only product is uploaded while there exists a multi-channel product that is effective for any marketing method for physical stores, with the same product ID, content language, and feed label. In this case, the local-only product fails to be uploaded and the “Product ID already used” error is returned.
- A multi-channel product that targets any marketing method for physical stores and has local inventory or online vehicle fulfillment cannot become effective for the marketing method because there exists a local-only product with the same product ID, content language, and feed label. In this case, the multi-channel product is disapproved for the marketing method with the “Product ID already used” error.
How to fix the issue
If the issue occurs on local-only product insertion
- Check if the local-only product is necessary: a local-only product might not be necessary as you already have a multi-channel product that is already being used with marketing methods for physical stores.
- If a local-only product that is different from the multi-channel product is necessary, use a different product ID.
- If you do need different products for different marketing methods with the same product ID, remove the existing multi-channel product. Then, reinsert with all marketing methods for physical stores excluded with help of the excluded destination
[destination_excluded]attribute, or reinsert it through a data source that targets marketing methods for online store only. You will be able to insert your local-only product after 5 minutes.
If the issue is reported for a multi-channel product
- Check if the conflicting local-only product is necessary: it might not be necessary as you already have a multi-channel product that is ready to be used with marketing methods for physical stores.
- If the conflicting local-only product is necessary, use a different product ID.
- If the multi-channel product does not need to be used with marketing methods for physical stores, exclude all marketing methods for physical stores with help of the excluded destination
[destination_excluded]attribute or reinsert it through a data source that targets marketing methods for online store only.
