> *Business Case*
>  Many a times its required to promise the delivery date to customers for her sales orders
that are back-order (BO) based on the expected arrival of future incoming/purchase shipments.
Currently its not possible without either manually pegging the supply to demand or having
the MRP run.
> *Scope*
> The scope of demand versus supply pegging is limited to purchase shipments only assuming
that shipment data would be synced back in Ofbiz and procurement/replenishment would be external
to OFbiz universe. If that is not the case then MRP run might be preferred way to achieve
the same.   
> *Possible Solution*
>  To solve for this problem on real time basis, the Reservation flow can be leveraged
as that makes the determination whether the punched in sales order (or demand for production
run for that matter) is going to be backordered or not.
> If and when there is SHIPMENT.ESTIMATED_ARRIVAL_DATE available against the scheduled
or incoming receipts in the system say with SHIPMENT_TYPE_ID=PURCHASE_SHIPMENT (or INCOMING_SHIPMENT)
then the reservation or post-reservation run can be triggered to peg and allocate the expected
shipment volume to backorders on FIFO basis and inherit the earliest SHIPMENT.ESTIMATED_ARRIVAL_DATE
over  ORDER_ITEM_SHIP_GRP_INV_RES.PROMISED_DATETIME which can be promised and communicated
to customer.
> *Use Cases*
>  1. Product GZ-2644 has 50 units backordered across 2 sales order placed on different
dates:
>  ORDER_1 : Placed as BO on 01/01/2020 with Order Qty = 30 units with all units backordered
>  ORDER_2 : Placed as BO on 01/03/2020 with Order Qty = 20 units with all units backordered
> Two Shipments for Product GZ-2644 scheduled to arrive on different dates as follows:
>  SHIPMENT_1 : Estimated Arrival Date on 01/25/2020 with Qty=20 units
>  SHIPMENT_2 : Estimated Arrival Date on 01/31/2020 with Qty=40 units
> _*Expected Result*_
>  Upon reservation, here is how they would get their promised date:
>  ORDER_1: Although its pegged to both the shipment (i.e., 20 units from SHIPMENT_1 and
10 units from SHIPMENT_2) but gets the Promise Date of 01/25/2020 (as shortness takes precedence
over lateness)
>  ORDER_2: It gets pegged to second shipment (20 units from SHIPMENT_2) and gets the Promise
Date of 01/31/2020 
> 2. Product GZ-2644 has 50 units backordered across 2 sales order placed on different
dates but also has Safety Stock threshold of 30 units to be maintained:
>  ORDER_1 : Placed as BO on 01/01/2020 with Order Qty = 30 units with all units backordered
>  ORDER_2 : Placed as BO on 01/03/2020 with Order Qty = 20 units with all units backordered
> Two Shipments for Product GZ-2644 scheduled to arrive on different dates as follows:
>  SHIPMENT_1 : Estimated Arrival Date on 01/25/2020 with Qty=20 units
>  SHIPMENT_2 : Estimated Arrival Date on 01/31/2020 with Qty=40 units
> _*Expected Result*_
>  Upon reservation, here is how they would get their promised date:
>  ORDER_1: After allocating 30 units for Safety Stock (i,e., 20 units from SHIPMENT_1
and 10 units from SHIPMENT_2), its pegged to the second shipment (i.e., 20 units left from
SHIPMENT_2) and gets the Promise Date of 01/31/2020 (as Safety Stock takes precedence over
sales orders)
>  ORDER_2: It gets no shipment left to peg to and hence no promised date or can be defaulted
based on average lead time from supplier.
