Overview

Error 8045 is a product feed error that Amazon sellers encounter when a SKU has conflicting parentage classifications across different marketplaces. This error occurs when a SKU is set up as a variation parent in one store but submitted as a variation child in another, causing a classification mismatch that prevents the feed from processing successfully.

Key Points / What Sellers Need to Know

• Parentage classification must be consistent — Every SKU on Amazon is classified as either a "parent" or a "child" in a variation relationship, and this classification must match across all marketplaces where the SKU is listed.
• The parentage column in product feeds controls classification — The item classification is defined in the "parentage" column of your product feed. If you leave this field blank, Amazon defaults the SKU to "child" status.
• Conflicting submissions trigger the error — If you submit a feed where a SKU's parentage differs from what is already established in another marketplace, Amazon will reject the submission with Error 8045.
• Deletion and recreation may be required — In some cases, resolving this error requires deleting the SKU from all active stores and recreating it with the correct, consistent parentage classification.

How Variation Parentage Works

Amazon's catalog system uses a parent-child relationship structure to organize product variations. A parent SKU serves as the main listing that groups related products together, while child SKUs represent the individual purchasable variations such as different sizes, colors, or styles. This classification is a fundamental part of how Amazon organizes listings, and it must remain uniform across every marketplace where a seller operates. When you submit product data through feeds, the parentage column determines whether Amazon treats each SKU as a parent or a child. Leaving this field empty causes Amazon to automatically assign the SKU as a child, which can inadvertently create conflicts if the SKU was already established as a parent in another marketplace.

How to Resolve Error 8045

The first step in resolving this error is to verify the current parentage classification of the affected SKU across all of your active marketplaces. Check each store to determine whether the SKU is listed as a parent or a child, and identify where the inconsistency exists. If you simply submitted the wrong classification in a feed, you can correct it by resubmitting the feed with the accurate parentage value that matches the SKU's existing status. However, if you need to change a SKU's classification from child to parent or vice versa, the process is more involved. You must delete the SKU from all active stores first, wait at least 24 hours for Amazon's systems to fully process the deletion, and then recreate the SKU with the correct and consistent parentage classification across all marketplaces.
