Creating Planned Independent Requirements for each Production Lot 
Use
In order to be able to carry out production lot planning, you can create planned independent requirements with reference to the production lot, that is, you enter a WBS element, for the material in Demand Management.
You also create planned independent requirements if the material to be planned is an assembly with the material type HALB. In this case, dependent requirements are determined during the BOM explosion in the MRP run, but no procurements elements are created for them, as only the created planned independent requirements of the assembly are taken into account in MRP.
Integration
If you use sales and operations planning, you can also carry out flexible planning for each production lot and then transfer the results by entering the WBS element in Demand Management.
