Subcontracting Material MRP.

Question

Hi friends,
Here is my issue,
We have a material 'A' which is a subcontracting material and its subrequired material is 'B'.
when we run MRP (MD04) for the material 'A', here it generating the PR's as required. but when we run
the same for material 'B' it is generating the Planned orders (pldOrd). but this material is not in-house
produced one..
Why it is generating the pldOrd for the material B
Please explain why it is happening and how it should be corrected.
Regards,
Mohan.

Answer 1

Hi,
Check the below settings
1. For Matrl A Ensure the MRP2 , Procurement key is F and spl.proc.key is 30
2.For Matrl B ensure the MRP2 has the Proc key F if you are buying this product externally
Hope you would have maintained BOM as Matrl A header and Matrl B as lower material
3. If you need PR to be generated, Put MRP relevant indicator as '1' in source list by giving proper vendor
4. If you need Sch lines to be created,enter the Sch.agrmnt # in the source list and give MRP relevant
5.Run the MRP for Matrl A in MD03,give the below MRP Control Parameters
           Processing Key NETCH
           Create Pur req    1
           Delivery Sch       3
           Create MRP       1
           Planning mode   3
           Scheduling         2
6.By this MRP run,the lower level material also will get run automatically.
7. If not,run MD02 with the above MRP control parameters 1,3,1,3,2
