Technical Information on How the Planning Run Works: Summary (1) The steps of material requirement planning consists if net requirements calculation, determining the procurement type, scheduling and the BOM explosion. The net requirements calculation determines the available quantity for planning. The lot-sizing procedures and the procurements type are assigned in the material master.

Technical Information on How the Planning Run Works: Summary (2) Basic scheduling or the lead time scheduling are two possible scheduling types in MRP. The BOM selection is influenced by the selection ID, the alternative selection indicator and the selection of the explosion date.
