Hello Mahesh Kumar,
Please go to MM02, MRP1 View and select the MRP type ND ( No Planning), So for this three component. In that case system not run MRP for this three materail,
Or you can set the Bulk material as per Expert Chinna suggested
Mark the material as bulk in the material master (MRP 2 View), that should fulfill your requirement.
NB: No need of un-checking costing relevancy in BOM if you make it bulk at material master level
For this please refer below thread
Re: how to activate and deactivate the line items in bom
I hope this information helpful to you
Regards
Umesh Mali
