Question :
I have a plant in which for many materials, I have assigned MRP Controller.
Now I want to know that for only this MRP controller, can I set MRP run automatically in backend, daily at time 23.59 ? Is this possible?
If yes then please tell me how to do this? and what are prereuisites for this?
Answer :
This question has been as below :
1.First create the variant for the MRP run,using T.Code MDBT --->mention the plant,MRP control parameters--->User Exit key(First the user Exit M61X0001- MRP run based on MRP controller should be activated).
2.MRP job can be scheduled either from T.Code SM36(for the Program name RMMRP000 and selecting the proper variant) or else from MDBT by clicking the schedule and mention it for daily option,the time details etc.
3.The results can be checked in SP01 or else SM37.
Go to OMIX and create user keys with same as MRP controller code and give some (any) description in user parameter.
Now go to SE37 and enter the following exits names and get an idea of the ABAP code
EXIT_SAPMM61X_001
EXIT_SAPLM61C_001
You will see ZX includes, go to SE38 and create them with same name you saw in SE37.
Now in the includes add the code similar to the following code:
*&---------------------------------------------------------*
*& Include ZXM61U01
*&---------------------------------------------------------*
CLEAR: no_planning, stop_planning.
IF user_key = ‘B01‘.
IF mt61d-dispo = ‘B01‘. "Plan only MRP Controller B01
*Continue
ELSE.
no_planning = ‘X‘. " Exclude all others
ENDIF.
ENDIF.
IF user_key = ‘B02‘.
IF mt61d-dispo = ‘B02‘. "Plan only MRP Controller B02
*Continue
ELSE.
no_planning = ‘X‘. " Exclude all others
ENDIF.
ENDIF.
As far as I know you need to have the same code in both the user exits else the user exit doesn‘t work.
Automatic scheduling MRP run for specific MRP controller
