Purchase Requistion - delivery date

hi

there is a sub DC where replenishment takes place from a bigger DC only when safety stock goes down.

now when the safety stock goes down say today, MRP generates PR which has delivery date as today and with a release date in past based on planned delivery time, GR time etc.

but in real sense, it would be apt if system tells the delivery date in future considering the lead times and release date as today..

can it be attained by fwd scheduling ? if so how do i do for selective plants.

Pls suggest.

regards

joe
