HI

I have same raw material has two separate demands coming from different activities (for example, 10 units from Activity A and 12 units from Activity B). As a result, two separate purchase requisitions are created for each activity (10 and 12 respectively) by PMRP.

 

However, when reviewing the MRP Part Information in the bottom-up view, I notice what appears to be duplicate records. When I drill down from each activity, I can see two bottom-up MRP records.

 

At the next level under each of these records, both demands (10 and 12) are shown together.

 

Is this behavior correct? Shouldn’t each activity node display only its respective demand instead of combining both?

 

MRP bottom up planning records seems to be showing, the respective demand record + all the other demands coming from the other activities for the part. 

How can we correctly interpret and explain the business value to the customer?

 

One Bottom up record 

Supply  10 pcs  Part K -  ( Activity A)

+---------------------Demand 10 Pcs Part L ( Activity A)

+----------------------Demand 24 Pcs Part L ( Activity B)

 

Other Bottom up record 

Supply  24 pcs  Part K -  ( Activity B)

+---------------------Demand 10 Pcs Part L ( Activity A)

+----------------------Demand 24 Pcs Part L ( Activity B)

Thank You.
