Request ACES coverage and fitment attributes gap reports
Use the Fitment reports to identify catalog issues that affect automotive compatibility data.
ACES stands for Automotive Aftermarket Catalog Exchange Standard (Auto Care Association). It defines how vehicle fitment information, such as year, make, model, engine, and related qualifiers, is structured and exchanged.
Report types
Two report types are available. Choose the report that matches your goal:
| Report | reportType | Description |
|---|---|---|
| Fitment missing ACES coverage | FITMENT_ACES_COVERAGE | Identifies items that do not have ACES coverage in Walmart systems. |
| Fitment missing attributes | FITMENT_MISSING_ATTR | Identifies items with one or more required ACES attributes missing, such as Part Terminology ID or vehicle qualifiers. |
