The 947 reports changes a warehouse makes to inventory it holds for a trading partner: damage, theft, cycle-count variances, returns, or expiry. Each adjustment carries a reason code and quantity at the item level so the owner of the goods can post the same change in its own system. Depositors require it because sellable inventory recorded for a 3PL location must match what the warehouse actually has, or orders will be accepted against stock that does not exist. Sent by the 3PL or warehouse to the owner of the inventory, typically a manufacturer, supplier, or retailer.
When it fires: A cycle count, physical inventory, damage event, or product expiration at the warehouse changes on-hand quantity outside the normal ship and receive flow.
Common 947 rejection causes
- Missing or invalid adjustment reason codes, leaving the depositor unable to classify the variance or post it correctly.
- Adjustment direction errors, where an increase is transmitted as a decrease or vice versa, doubling the variance instead of correcting it.
- Product identifiers (SKU or UPC) that do not match the depositor's item master, so the adjustment cannot be applied.
- Adjustments that are never reconciled against periodic inventory reports, leaving a persistent gap between warehouse and depositor on-hand counts.
