Walmart invalid Product ID.
A check digit can be tested mathematically, but changing an identifier could point to a different product. V1 therefore reports invalid identifiers instead of guessing a replacement.
What can be repaired safely
- Removal of invisible characters around an otherwise unchanged value
- Clear identification of the affected row
- Preservation of the original identifier
What still needs review
Invalid check digits, ownership conflicts, and exemptions require an authoritative identifier or Walmart action.
