Run MRP by vendor

Question

Hi,
Do you know if there is any way to run MRP by vendor ?
We would like to define for a planning run only material of a particular vendor.
Thanks,
PYR

I suggest you use 'MD01' specifying using a user-exit (created in customizing) and a user-exit parameter. First, you create a user-exit in the customizing, then with the help of an abaper you program the exit 'EXIT_SAPMM61X_001' where you  code something like this:
clear: no_planning, stop_planning.
   case user_key.
    when 'ZVE'. " Your user-exit
       data wa_lfa1 type lfa1.
       data lv_lifnr type lifnr.
       if user_par is initial. " Stop planning if user parameter is not specified
         stop_planning = 'X'.
       else.
         move user_par to lv_lifnr. " This is the user-exit parameter
         call function 'CONVERSION_EXIT_ALPHA_INPUT' " Convert the vendor code
           exporting
             input         = lv_lifnr
           importing
             output        = lv_lifnr.
         select single * from lfa1 into wa_lfa1 where lifnr eq lv_lifnr. " Verify that vendor exists
         if sy-subrc ne 0. " ¿Doesn't exist? then no planning
           stop_planning = 'X'.
         endif.
When you execute 'MD01' you specify user-exit = 'ZVE' and user-exit parameter = 'the vendor code'.
Hope it helps.
