critical FITMENT_ERROR

Fitment Data Error (Auto Parts)

What this means

Auto-parts fitment file failed validation - usually a YMME (Year/Make/Model/Engine) reference that doesn't match Walmart's vehicle taxonomy.

Why this happens

Walmart Seller Center's product schema has format and value rules per attribute. This issue is typically: missing a required attribute for the category, an invalid enum value (e.g., 'XL' submitted where 'M, L, XL' is the valid set), out-of-range numbers, or attributes that conflict across the feed.

How to fix it

  1. Look up the affected attribute in Walmart Seller Center's product data spec.
  2. Check whether the attribute is REQUIRED vs RECOMMENDED for your product category.
  3. For enum-style attributes (gender, age_group, condition), use ONLY documented values exactly (case-sensitive).
  4. For free-text attributes, stay within the character limit and avoid promotional language.
  5. Re-submit and check the next processing cycle.
