Master Planning

I have the following 3 scenarios. Would request a setup that need to be done:

Scenario - A:

In the above data:

a. The Demand has been Manual entry in the Master Planning

b. The Sales Order Quantity are different Sales Orders are created for the same item in different dates .

c. MRP Re-Run is the Master Planning being run in the defined dates.

Configuration Done:

1. Reduction Key method used in Master Plan : "Transactions - reduction key"

2. Coverage Group : Reduce Forecast By : Orders

Problem faced:

a. The MRP Rerun values at 13-Jan-2018 showing 80 but when we are re-running MRP on 15-Jan-2018 , the values are not considering the total sales orders quantities i.e. 70+5.

b. Similar problem is perceived in the consecutive MRP - Re run dates.

Would request if I am missing anything .......
