How to Fix Error 99006: Missing Dependent Attribute Fields in Amazon Listings
Error 99006 occurs when a feed includes a dependent attribute (e.g., size map) without its companion field (size type). The processing report pinpoints the missing attribute, and the listing is blocked until the seller adds the value and re‑uploads the feed.
Overview
Amazon sellers encounter error 99006 when a product feed includes an attribute that depends on another field left blank. The system blocks the listing until all required companion attributes are supplied. Fixing the issue promptly is essential to keep inventory live and avoid sales delays.
Key Points
- Dependent attributes must be paired — Filling a field such as “size map” obliges you to also provide the matching “size type,” otherwise the feed is rejected.
- Error message pinpoints the gap — The 99006 response lists the exact attribute that is missing, allowing quick identification of the problem column.
- Typical culprits are size and material groups — Supplying a “material type” without the accompanying “material composition,” or entering a “size map” without a “size type,” are common triggers.
- Resolution requires a fresh feed upload — After inserting the missing values, the corrected file must be resubmitted for the listings to process.
- Bulk submissions can generate multiple instances — If dozens of SKUs share the same omission, each will generate its own 99006 entry in the processing report.
- Pre‑submission templates reduce risk — Using Amazon‑provided category templates highlights conditionally required fields, helping sellers avoid the error altogether.
How Dependent Attributes Work
- Attribute grouping — Amazon organizes related fields into dependency clusters; when one member of a cluster receives a value, the system expects all other members to be populated.
- Validation during feed intake — As the feed is parsed, the platform checks each cluster; any empty required member triggers error 99006.
- Category‑specific rules — Different product categories define distinct dependency sets; for apparel, size‑related attributes form a cluster, while for home goods, material‑related attributes are linked.
How to Fix Error 99006
- Locate the error in the processing report — Open the feed processing summary generated after submission; find the row labeled “Error 99006” and note the attribute name shown (e.g., “size type”).
Analysis & Recommendations
Why This Matters
While error 99006 does not affect account health, it halts product activation, delaying sales especially during peak periods. Each omitted dependent field generates a separate error entry, so dozens of SKUs can create many blocked listings.
Key Takeaways
- Error 99006 blocks listings until the missing dependent attribute (e.g., size type) is supplied.
- Amazon’s processing report lists the exact attribute name that is missing, enabling quick identification.
- Common dependency pairs are size map ↔ size type and material type ↔ material composition.
- Resubmitting the corrected feed via Seller Central’s “Add Products via Upload” clears the error.
Recommended Actions
- →Open Seller Central > Inventory > Add Products via Upload, download the processing report, filter for “99006”, and note the missing attribute column.
- →Edit the original spreadsheet or XML, fill the missing dependent field for each flagged SKU, then save.
- →Re‑upload the corrected file through Seller Central > Inventory > Add Products via Upload and verify the new processing report shows no 99006 entries.
