Walmart recently updated their EDI 855 (PO Acknowledgment) specification. The quantity in ACK02 (segment ACK, element two) is now required rather than optional. You must include the specific item quantity that you’re acknowledging in ACK02 or Walmart will count it as an error.

Make sure your Walmart 855 map is set to always include ACK02 so your 855’s aren’t rejected. 855 rejections can lead to subsequent 856 rejections (even if there’s no error) and ultimately to 810 rejections, affecting your receivables and causing extra work.
