Overview

Error 99015 is a feed processing error that Amazon sellers encounter when uploading product listings through flat files or inventory feeds. This error occurs when two columns in your upload file contain values that contradict each other, preventing Amazon from processing the listing correctly. Understanding and resolving this error quickly is essential for keeping your product catalog accurate and your listings live.

Key Points / What Sellers Need to Know

• Conflicting Data Fields — Error 99015 triggers when the value entered in one column of your feed file directly contradicts the value entered in another column within the same row. Amazon's system cannot reconcile the mismatch and rejects the submission.
• Common Trigger Scenarios — This conflict frequently arises with fields that have logical dependencies, such as product type and category-specific attributes, variation theme and child listing details, or fulfillment channel and shipping-related fields.
• Feed-Level Error — This is a validation error that occurs during feed processing, meaning the affected listings will not be created or updated until the conflict is resolved and the file is resubmitted.
• Resolution Requires Manual Review — You need to open your upload file, identify the two columns flagged in the error message, determine which value is correct, and update the conflicting entry before resubmitting.

How This Error Occurs

When you upload a product feed to Amazon — whether through Seller Central's flat file upload, the Add Products via Upload tool, or via the Selling Partner API — Amazon validates every row against a set of business rules. Some columns have logical relationships where certain value combinations are not permitted. For example, if you specify a product as a parent listing in one column but then include child-specific attributes like size or color in another column on the same row, the system detects this as a conflict. Similarly, setting a fulfillment channel to "Merchant Fulfilled" while populating FBA-specific fields like prep instructions can cause this mismatch. The error message itself identifies the two columns involved, using a format like "The value in column X conflicts with the value in column Y," which serves as your roadmap for fixing the issue.
