Overview

Error 90147 is a feed validation error that Amazon returns when one listing attribute value fails a "less than or equal to" comparison against another related attribute. This commonly surfaces when sellers submit product feeds with inconsistent pricing, dates, or quantity ranges. Understanding this error helps sellers quickly correct their data and avoid listing processing delays.

Key Points / What Sellers Need to Know

• Attribute comparison failure — This error fires when a value that should be smaller than or equal to another value is actually larger. Amazon enforces logical relationships between paired fields in your product data.
• Pricing is the most common trigger — If your cost price exceeds your list price, Amazon flags the inconsistency. For example, a cost price of $126.10 paired with a list price of $33.21 will generate this error.
• Date ranges must be chronological — Start dates must come before end dates. Submitting a start date of April 1, 2024 with an end date of March 31, 2024 will trigger error 90147.
• Quantity minimums and maximums matter — Any field where a minimum value exceeds the corresponding maximum value will also cause this validation to fail.
• The fix requires resubmission — Once you correct the offending attribute, you need to resubmit your feed file for the changes to take effect.

How This Error Works

Amazon's feed processing system performs automated validation checks on related attribute pairs before accepting product data. When you submit a feed file containing fields that have a logical "less than or equal to" relationship, the system compares the left attribute value against the right attribute value. If the left value is greater than the right value, the system rejects that specific entry and returns error 90147. The error message itself will identify both the attribute names and their values, making it straightforward to locate the problem in your data.

Common Scenarios That Trigger This Error

The most frequent cause is a pricing mismatch, where cost price or sale price accidentally exceeds the standard list price. This can happen through manual data entry mistakes, spreadsheet formula errors, or currency conversion issues when managing international listings. Date-related triggers are also common, particularly for promotional pricing windows or availability periods where start and end dates get swapped. Sellers managing inventory with minimum and maximum order quantities can also encounter this error if those values are reversed in their feed files.
