Duplicate product IDs in feed

Two or more rows share the same id. Snapchat does not pick one - both are blocked from publishing until each row has a unique identifier.

Variant feeds where each color or size accidentally inherits the parent SKU, joins between two data sources without de-duplicating, or transformations that strip the variant suffix before export. Snapchat treats id as a strict primary key.

1. Run a duplicate check on the id column.
2. Append a variant identifier to each row to make the ID unique.
3. If two products genuinely share an SKU, merge them in your PIM.
4. Set up a pre-export validation that fails on any duplicate.
5. Resubmit and confirm the duplicate-id error clears.

• Mixing parent and child IDs without item_group_id to disambiguate
