Amazon error 8804: The family is inconsistent
What does it mean?
An attribute such as the brand must be identical for all members. The products are listed, but the relationship is not created.
How to fix it
Make the attribute identical everywhere, including spaces and capitals.
Where do you fix it?
- In your product data (your source)
- 8016Not enough data to create the variation relationship
- 8007The parent SKU is not recognised
- 8008The child SKU is not recognised
- 8032The child is already assigned to another parent
- 8801Another child in the family has the same variation values
- 8802The relationship cannot be created
- 8805An update would make the SKU inconsistent with its family
- 8045The SKU is a parent in one marketplace and a child in another
