MRP - Schedule Line for Multilevel BOM

I have a BOM-- multilevel

When we are running MRP the system calculates the Schedule lines for the components , the thing is it takes the Maximum Lead time of 21 days which has been maintained in one of the components , the System takes this as the schedule line for the other item which is having the lead time of 6 days only .

please guide me why system is taking the max. lead time for all the items .

If i need the schedules according to the items how i can proceed

    The system should have taken like this:

    In one of the level of BOM, if one component has lead time 21 days, the other component has 6 days .This lowest lead component procurement should start last 6days of 21 days period..

    It should be like this only.

    Hope it is clear, else get back.

      You should maintain the master data properly.

      workcenter : yopu should maintain capcity header :


      active verison : should be maintained.

      either standard avaiable capacity or interval of available capacity to maintained.

      Relevent to finite scheduling should be checked.

      Formaulas in capcity & schediuling to be maintained.

      Controlkey should allow capacity & schedulung.

      MRP settings:

      under step: Define scheduling parameters for planned orders ( TCODE: OPU5).

      should be maintained.

      Finally MRP control parameters in the intial screen of MRP run select " lead time scheduling & cpacity planning for the field : scheduling,.

      with the abopve settings you should be able to achieve your results.

      Hope it is clear. else pl. update.
