Error 90003 — Parent-child relationship inconsistent

Your variation children reference a parent SKU that doesn't exist, has a different product type, or has incompatible variation attributes. Amazon can't link the children to the parent.

Children inherit the parent's product type and variation theme. If the parent was deleted, has a different product type, or hasn't been processed yet, the children fail to link.

1. Check that the parent SKU exists in your Manage Inventory and has a 'parent' relationship_type.
2. Submit the parent BEFORE the children — Amazon processes feeds sequentially, but the parent must be fully ingested before children can attach.
3. Verify children's product_type matches the parent's exactly — mismatches cause 90003.
4. Confirm parent_sku in each child row matches the parent's actual SKU exactly (case-sensitive).

• Submitting parent and children in the same feed in the wrong order — list parent first
• Typos in parent_sku breaking the link
