Overview

Error 90004116 is a feed processing error in Amazon Seller Central that occurs when a product listing submission includes values for a non-required attribute that conflicts with a mandatory attribute. This error typically surfaces during flat file uploads or feed submissions when attribute rules are violated, preventing the listing from being created or updated. Understanding how to diagnose and resolve this error can save sellers significant time when managing catalog listings at scale.

Key Points / What Sellers Need to Know

• Attribute value limit exceeded — This error is triggered when a non-required attribute field contains more values than Amazon permits, specifically when the allowed maximum is zero values but a value has been submitted.
• Conflicting attribute rules — The root cause involves submitting a value for an optional attribute alongside a mandatory attribute that creates a conflict, making the optional attribute invalid in that context.
• Conditional requirements exist — Certain attributes become mandatory or prohibited depending on the values entered for other attributes. For example, updating the age_range_description attribute can change whether other fields are required or forbidden.
• Resolution requires removing conflicting values — The fix involves identifying and removing values from the non-required attribute that is causing the conflict, then resubmitting the feed file.

How This Error Occurs

When sellers upload product data through flat files or inventory feeds, Amazon validates each attribute against a set of rules that can change dynamically based on the values of other fields. Error 90004116 is generated when the system detects that a non-required attribute has been populated with values even though the current configuration of mandatory attributes does not permit it. In many cases, this happens because sellers fill in every available column in their flat file template without realizing that certain field combinations are mutually exclusive. The error message will reference two specific attributes — the non-required field causing the problem and the mandatory field that triggers the restriction.
