Use
Preliminary requirements are created by assigning material components to the advance procurement activity in the generator network during BOM transfer. Preliminary requirements serve as coverage for real requirements that are generated at a later stage. This is useful for material components with a long replenishment lead time.
Planned independent requirements are generated (instead of reservations) for materials that are procured using MRP (item category L).

In the results overview you can see the components of the multi-level BOM that will be assigned to the appropriate activities of the project due to their common reference points. The components are assigned when you save your data.
Result
After you have assigned materials IECPP-2-GE12 and IECPP-2-GE13 to the activity and the activity has been released, the system creates planned independent requirements to cover the requirements.
