Understand how total lead times are rolled up to give the different total cumulative lead times depending on stocking levels of subassemblies and purchased components. Total Lead Time Preprocessing lead time plus processing lead time for an item Used by Oracle Master Scheduling/MRP as on option when defining time fences. Cumulative Manufacturing Lead Time Processing lead time plus critical path subassembly processing lead times. The time required to build an item if all purchased components are stocked, but subassemblies must be built level by level. Used by Oracle Master Scheduling/MRP as an option when defining time fences. Cumulative Total Lead Time Processing lead time plus critical path subassembly and purchased component processing lead times. The time required to build an item if purchased components must be purchased and subassemblies must be built level by level Used by Oracle Master Scheduling/MRP as an option when defining time fences. Order Modifier An item attribute that controls the size of planned orders suggested by the planning process in line with your inventory policies. Minimum Order Quantity Define a minimum production or purchasing quantity For example, when an item has high set-up costs, capacity limitations, or because if is simply not economical to build or purchase the item in small quantities: Net Requirements = 50, Minimum Order Quantity = 100, Planned Order = 100. Maximum Order Quantity Define a maximum production or purchasing quantity. If net requirements exceed the maximum order quantity, the planning process suggests multiple planned orders. For example, represents production, warehouse, or transportation capacity constraints: Net Requirements = 200, Maximum Order Quantity = 150, Planned Order Quantities = 150 + 50. Fixed Lot Multiple Define a production or purchasing quantity, where the planning process must suggest planned orders for the defined quantiy or multiples of the defined quantity. For example, when a vendor can
