Amazon Listing Errors: Error 990102: Relationship from parent SKU 52050 to child SKU 52050 was refused because the SKU 52050 would enter a circular relationship when traversing package_contains hierarchy relationships from the root

Error Description

The "Error 990102: Relationship from parent SKU 52050 to child SKU 52050 was refused because the SKU 52050 would enter a circular relationship when traversing package_contains hierarchy relationships from the root" error indicates that the relationship defined between the parent SKU and its child SKU creates a circular reference. This means that when Amazon tries to follow the hierarchy from the parent to the child, it encounters the same SKU again, leading to an infinite loop.

Common Causes:

Incorrect Parent-Child Definition: Defining a SKU as both a parent and a child, leading to a loop.
Data Entry Errors: Mistakenly assigning the same SKU to both parent and child roles.
Incorrect Template Usage: Using an incorrect template that does not properly define the hierarchical relationships.
