Not necessarily. WB API announced a new GET /api/supplies/v1/discrepancies/{supplyId} method and an added discrepancies field in FBW supply details. They expose differences between declared and actually accepted quantities. A quantity difference is an operational signal, not an automatically confirmed monetary loss.

Start at SKU and variant level. A net difference of three units might hide a shortage of one product and an overage of another. Save the supply ID, declared and accepted quantities, date of the provider response, raw evidence and claim status. Repeated reads of the same event must not create duplicate claims.

Match the API result with supply documents, packaging and shipment evidence. Assign an owner and a date for the next check. Use the accepted quantity when planning available stock, but wait for the corresponding financial document, adjustment or compensation before final P&L booking. Do not multiply the gap by the retail price and call it a loss.
