Distinguish between planned receipt and scheduled receipt?

Planned receipt is the receipt against a planned order yet to be released.

Scheduled receipt is the receipt against a released order.

Say the lead time for receipt of material X is 4 weeks from the date of order release and we are in week 10.

If an order was released in week 8, its scheduled receiptwill be in week 12.

Basis the consumption, current stocks, scheduled receipts and lead time, if a planner plans a order to be released in week 11, its delivery will be in week 15.

This receipt in week 15 is the planned receipt (the order is planned but not released)
