Fulfil can automatically create a supplier's shipment when a PO is processed. Merchants can also split the supplier shipment if it's receiving at different 3PLs, or it could also be split if some quantities are received by air. The remaining quantities are coming later by the ocean.
Workflow
Partial supplier receipt
When receiving items from suppliers, it could be a partial receipt or it could be an over receipt where the supplier shipped more than expected. In both cases, the rule of thumb is to always report the actual quantity received.
Receiving damaged items
If you receive items from a supplier that are damaged, always receive the quantity the supplier shipped. You can then use the inventory adjustments API to mark quantity as damaged.
