Question & Answer
Question
Demand is Communicated to External Systems
Answer
This flag is available in the pop-up when you try to create a new demand.
This flag has a use case only for those Nodes that track
supplies externally. In such cases Sterling uses GetExternalSupply user exit to
get the supplies from external systems to calculate the availability. Now the
supply quantity returned from this UE is actually the available quantity which
is calculated by excluding the demands with demand type that has
CommunicatedDemand=Y. (ie "Demand Is Communicated to External System" flag is
checked)
For an external system that already considered
"communicated demands" (Demands communicated from Sterling) in its supply
picture, the IgnoreCommunicatedDemands flag can be passed in the output of the
getExternalSupply user exit. This implies that Sterling should ignore all
demands with demand type that has CommunicatedDemand=Y during availability
calculation because the supply picture provided by external system already
excluded the quantities for such demands.
To explain this with an
example:
Say Sterling maintains following Demand types: (All the
supplies being maintained externally)
-- Open Order
--
Backordered
-- Allocated
-- Scheduled
And the
external system maintains only "Scheduled" Demand type, ie "Demand Is
Communicated to External System" flag is checked only for "Scheduled" demand
type.
Now say the Inventory Picture available to Sterling is:
Allocated = 2
Scheduled = 3
External Inventory
Picture:
Onhand=10 (Supply)
Scheduled=3 (Demand)
Now GetExternalSupply UE will pass only 7 as the Onhand quantity and use
this to calculate the availability. Now if IgnoreCommunicatedDemands flag is
passed as Y from the UE, then Sterling will ignore the "Scheduled" demand type
available to Sterling and calculate the availability as 7-2=5.
But if
IgnoreCommunicatedDemands is passed as N, then Sterling will consider all the
demand types to calculate availability. In this case availability = 7-2-3 = 2.
