Hi all,

I'm struggling to list a new standalone product, but my flat file keeps returning two errors:

8008 – Your child SKU is not set up correctly. Check if there are any product-related errors that prevented child SKU creation. Fix them first before trying to create any relationship.

990100 – The parent SKU was refused because there exists at least one non-approved package_contains relationship. Address any other issues associated with the SKU before resubmitting the relationship.

The confusing part is that this item isn't part of any variation family—it’s neither a parent nor a child. I'm leaving all parentage-related fields blank: Parentage, Parent SKU, Child Relationship Type, and Variation Theme Name.

I’ve contacted Seller Support and they advised to leave the Package Contains SKU Quantity and Package Contains SKU Identifier fields blank. I have done so, though I don't really understand why as this is a standalone unit, and these fields are optional and seem to be more relevant for multi pack items.

They weren’t able to assist further, and I’ve been receiving canned responses since. So I thought I’d ask here in case anyone has encountered a similar issue or has insight into what might be causing these errors.

If this message is being reviewed by an Amazon representative, the batch ID is: 5431964020286.

Thanks!
