Ware house pallet

Dear friends,

I have done purchase order for 1000 quantity by assigning pallet id for it.What does this pallet id do for this purchase order?

Is it mean that, i should transfer the goods to the in bound dock of the warehouse only with this one pallet.But i have the pallets of the same type of 10 quantity(i mean 10 pallets of same type).

If i go to inventory amangement – > setup— > pallets and click onhand button of this particular palletid, it is showing inventory onhand.What does this mean?

thanks in advance
