Difference in behavior between reserveAvailbleInventory API and scheduleorder API

Answer

Steps to Configure:

1. Optimize on Cost, Number of Shipments is set in Scheduling Rules.
   
   
2. Check the option A line can be fulfilled from a single node only in Application Manager-Distributed Order Management-Document specific-Sales Order-Fulfillment rules.
   
   
3. Distance/mile based sourcing enabled:
   Store 1 and store 2 at a distance of 200 miles from a buyer A
   Store 3 at a distance of 600 miles from the same buyer A
   Sequence 1 of the sourcing rule says- consider store at a distance less than 500 miles
   Sequence 2 of the sourcing rule says-consider store at a distance less than 1000 miles
   10 quantity of an item available at each of the stores (Store 1 and Store 2 ) and 20 quantity of item available at the node Store 3
   
   
   Now, If you run resereveAvailableInventory for 20 quantity it reserves the quantity at the stores Store 1 and store 2 which have 10 quantity of the item each,
   If you schedule an order it schedules the inventory at store 3 which has 20 quantity available
   
   
   The difference in the behavior of reserveAvailableInventory API and scheduleOrder API is due to the following configurations:

• To get reserveavailableInventory to work as scheduleOrder API, you will need to check Line Ship From Single Node in scheduling rule configuration.
  
  
• For scheduleOrder API to act like reserveAvailableInventory API you need to uncheck A line can be fulfilled from a single node only.
