How does Yantra (hard/soft) allocate demand against FEFO time sensitive inventory supply

Resolving The Problem

shipByDate:
This can be looked in as an expiration date of an item. While adjusting inventory we can give shipByDate for that set of inventory which we are adjusting. If the shipByDate is not provided then Yantra calculates it as:
-- "today + item's default expiration days", for Supply Type of type Onhand
-- "ETA + item's default expiration days", for Supply Type of type other than Onhand. (ETA = Estimated Time of Arrival)

minShipByDate:
This is an orderline attribute. If minShipByDate is specified in the orderline then Yantra will allocate (Soft-matching) the Demand against Supply with
ShipByDate >= minShipByDate.

This is valid only for time sensitive items. Business use case for this is:

Say the inventory picture is like this:

ItemID ShipByDate
---------- -------------------

ITEM01 12/10/2005
ITEM01 12/20/2005

Now if we place an order on 12/05/2005, Yantra will allocate DEMAND against Supply with ShipByDate as 12/10/2005. But due to some constraints we know that we won't be able to process the order by 12/10/2005, in this case we can override this by providing minShipByDate of 12/11/2005 (say). Now Yantra will allocate against Supply with ShipByDate as 12/20/2005.

For more information about minShipByDate please refer to Ch-9.2.1.3 - Product Concept Guide.

So this way whenever an order is created/scheduled/released it is soft allocated according to FEFO.


The option of NOT selecting inventory according to FEFO comes into picture only when we are confirming a shipment.

There is a flag in inventory rules (Applications -> IS -> Inventory Rules -> Other Rules)
"Assume FEFO if no 'Ship By Date' is provided"

This 'Ship By Date' is a shipmentline level attribute and is mandatory for time sensitive items. While confirming shipment, Demand is hard-allocated against Supply with shipByDate = 'Ship By Date' (provided at the shipmentline level).
But if above flag is checked then 'Ship By Date' is not mandatory and Demand is hard-allocated against Supply according to FEFO.

Say in the above example if the 'Ship By Date' = 12/20/2005 then Demand will be hard allocated against Supply with shipByDate = 12/20/2005, otherwise (if above flag is checked and 'Ship By Date' is not provided) Demand will be hard-allocated against Supply with shipByDate = 12/10/2005.
