Phases of the Planning Process
You calculate material requirements by launching the planning process from the Launch Planning Process window. The phases of the planning process that calculate material requirements are the:
- maintain repetitive planning periods phase
Maintain Repetitive Planning Periods Phase
When you specify a new anchor date, the maintain repetitive planning periods phase uses that date as its new starting point for calculating repetitive planning periods.
Snapshot Phase
The snapshot phase:
- determines the component usages of the assemblies included in the planning process, beginning at the top level of the assemblies and working down through the product structure
- calculates low-level codes and checks for loops in your bill of material structures
- collects inventory on-hand quantities and scheduled receipts
- stores this information for further use
- captures resource information that is used for capacity planning
Planner Phase
The planner phase:
- performs the gross-to-net explosion, calculating net requirements from gross requirements, using on-hand inventory and scheduled receipts, exploding the requirements down through the bill of material
- suggests the rescheduling of existing orders and the planning of new orders based on the net requirements
- calculates the resource requirements for supply orders
Note: This step is performed if Capacity Plan is enabled.
Auto-Release Phase
The auto-release phase:
- releases planned orders for items whose order date falls within their release time fence
Note: This step is performed for plans that have the Production flag enabled.
The recommendations generated by the planning process feed the capacity requirements planning, shop floor control, and purchasing activities of the organization.
