Hi,
is the components you are talking are Semi finished materials or Raw materials and Packing materials which are procured from vendors ???....
It is not a good idea to maintain planning strategy for Components which are part of BOM...these materials are automatically planned when the header materials of these components are planned....
If these components are not part of any BOM then you can try the option of using forecast based planning.. MRP type VV and maintain the forecasting view in the material master
You can also explore the option of consumption based planning like manual or automatic reorder point planning...
Thanks
Kumar
