Goal

Here is the summary
GOP plan is run once a day in the night.
GOP plan is used only for ATP checks and scheduling
All Planned orders, IR/ISO releases happens from other DC/Plant plans.
Other DC & Plant plans are unconstrained Plans.

Day 1: DC enters a customer orders for Model X sourced from Plant.schedules and Books the orders. No Onhand at DC.
  ATP is called here to get right SAD and SSD fir the customer Oder.
  End of the Day GOP plan and DC/Plant Plans run along with complete collections.
Day 2: In Morning- DC Plan recommends to purchase from plant. DCs purchases from Plant thru IR.
  This in turn created ISO for plant.
  End of the day again GOP plan and DC/Plant plans are run along with complete collections
Day3: No other action for this Sales order/IR/ISO

On Day 2, we are seeing Resources consumption is happening for DC order and we see it consume for ISO when it is created and ATP inserts demands into the ATP Plan
On Day 3 we are resources consumption only on ISO.

Question: Why on Day 2 we are seeing duplicate consumption. DC order is dependent demand, once ISO is created, it should release the Dependent demand consumption. But it is not happening, it is happening only on Day 3.
