Supply Planning Process
Supply Planning uses information from Manufacturing and the Logistics Data Repository. This helps the system to determine which component items are required to produce items defined in the schedule. The supply plan produces planned orders, planning suggestions, and supply planning exceptions.
The following list describes the supply planning process:
-
Create a snapshot containing planning input from the manufacturing and logistics data repository.
A snapshot records the inputs at the time of the planning run. Snapshots provide a lasting view of the information that is used for reporting, comparison, and more.
-
Use demand for items defined in the supply plan with the planning bills of materials (BOM) to determine the gross requirements for the components.
You can also use the on-hand inventory information, quantities on-order, and firm planned orders, and net gross component requirements.
-
Delete existing planned orders for the items and organizations within the plan definition.
Firm planned orders are not deleted or rescheduled, they are considered part of the netting process.
-
Use the BOM hierarchy, lot-size information, and component lead-times to offset the start dates for ordering the components. Create planned orders for each component.
-
Use the item definition and planning rules to determine which planned order type to create: purchase order, work order, or transfer order.
-
Quantities on order (purchase or work order) are considered during the process. Changes to reschedule in, reschedule out, or cancellation are suggested to fulfill the current net requirements.
-
When the system evaluates independent demand, it reviews the rescheduled and canceled purchase and work orders suggested by the supply plan.
-
Use planning rules to determine item sourcing when creating planned orders.
-
Trace the pegging information for each planned order and then store the results.
-
The planner produces planning suggestions using the supply planning work bench.
-
Produce exceptions noted during the supply planning process.
Some components can be the child of more than one assembly and could also be a service part.
