How are multiple receipts for a single order managed in the MFCS replenishment system?

For example:

One item request qty is 10, one pallet ship 6 units, and another pallet ship 4 units. What is the implication of this case?

How can we ensure that the replenishment engine does not classify the first shipment as 'under received' and avoid triggering a new purchase order or transfer to cover the missing quantity?

Many thanks
