Run MRP for PS MD51

Hi all,

I have a problem when run MRP for PS by MD51. I have a project structure below:

Project definition: K-52

1.WBS element: K-52-01

Network: 101

Activity: 101 - 10 (material A, quantity = 10)

2.WBS element: K-52-02

Network: 102

Activity: 102 - 10 (material A, quantity = 25)

WBS element: K-52-02-01

Network: 103

Activity: 103 - 10 (material A, quantity = 15)

WBS element: K-52-02-02

Network: 104

Activity: 104 - 10 (material A, quantity = 25)

Each activity, I choose generate reservation instead of PR directly.

1. When I run MRP by MD51 for project definition K-52, the system generated 4 planned order for material A of each activity. This's no problem

2. When I run MRP by MD51 for WBS element K-52-01, the system generated 4 planned order for each activity like when I run MRP for project definition. I just want run MRP for WBS element K-52-01, but I don't know what happen and how to fix it. This's the first problem.

3. When I run MRP by MD51 for WBS element K-52-02, the system generated 2 planned or ther for K-52-01 and K-52-02, I don't know how system generate planned order for K-52-01. This's the second problem.

4. When I run MRP for WBS element K-52-02-01, the system generated 2 planned or ther for K-52-01 and K-52-02-01, I don't know how system generate planned order for K-52-01. This's the third problem

5. When I run MRP for WBS element K-52-02-02, the system generated 2 planned or ther for K-52-01 and K-52-02-02, I don't know how system generate planned order for K-52-01 as like as run mrp for K-52-02-01 above. This's the fourth problem

How I fix that, hopping your support.

Thanks

Regard

    You mean to say, whichever WBSE you use to run MRP, the system creates planned order for K-52-01, material A 10 nos. + the particular WBSE material qty. or system creates total qty for only K-52-01

    • You say that if you run MRP for K-52-01, then all the reservations are processed for the entire project.

      I am not sure whether this could be your issue or not, but try checking this, Check whether K-52-01 is a grouping WBSE or not. Check the basic data tab and see whether '1' is assigned to the grouping WBSE field.
