Overview

Amazon returns error code 100475 when a bulk feed attempts to replace a product attribute with a version that omits or shortens information previously present. The platform flags the change to protect the completeness of listings, and sellers must correct the feed before the update can go live. Prompt resolution is essential to keep pricing, description, or compliance edits from stalling.

Key Points

• Attribute information loss detected — Amazon cross‑checks the incoming attribute values against the live record and raises the error if the new entry appears less detailed.
• Typical trigger: overly condensed text — Sellers who trim bullet points, specifications, or product titles often unintentionally remove data Amazon deems critical, prompting the warning.
• Applies to feed‑based updates — The error surfaces in the feed processing report, affecting users of flat‑file uploads, SP‑API feed submissions, or third‑party listing managers rather than manual edits in Seller Central.
• Easily avoided with a pre‑submission audit — Running a side‑by‑side comparison of the current listing and the proposed feed file catches most omissions before Amazon processes the upload.
• Does not affect account health — While the error blocks the specific attribute change, it does not generate policy violations or suspensions, but it can delay time‑sensitive modifications.

How the System Flags Missing Information

1. Initial catalog snapshot — Amazon stores the most recent attribute values for each SKU; for example, a 250‑character product description that includes dimensions, material, and warranty details.
2. Feed ingestion — When a seller uploads a flat file, the system extracts each attribute value; if the same description field now contains only 120 characters, the platform notes a reduction.
3. Content comparison engine — Amazon runs a diff algorithm that measures length, keyword presence, and key specification markers; missing “Warranty: 2 years” or omitted “Material: stainless steel” triggers the rule.
