Job Planning

The Requirements Planning module develops replenishment schedules for all parts.  For job-controlled parts, it uses a special job planning routine.  This routine breaks down each part's demand and supply by job, and aggregates on-hand inventory at the job level instead of at the part level.  The following steps occur during requirements planning generation for a job-controlled part.
1. Each requirement for the part is retrieved by required date and job number sequence.
2. The on-hand inventory balances for the part (in all locations and plants) are totaled by job and job group to determine the amount of inventory currently available for each job.
3. As each requirement is analyzed, the demand from a job is netted against the on-hand inventory that has been allocated for that job and any open purchase orders for the job.  If no inventory exists for that specific job, but it belongs to a job group, on-hand inventory and purchase orders that exists for the job group are used.  Any remaining demand is sourced from common stock.
4. If necessary, the system will create a planned manufacturing order or purchase order requisition for the part.  The job number is included on the order or requisition so that activity can be tracked by job.
In addition to creating orders, the Requirements Planning module will suggest changes to existing manufacturing orders that have not yet been firmed or released.  These proposed changes are listed on the Planning Action Report within Requirements Planning.  Manufacturing orders can be created, changed, and released within the Inventory Control module; purchase requisitions can be covered by purchase orders within the Purchasing module.
The system does not allow you to transfer a job controlled part or to create a job controlled transfer part (part type 8).  However, the system does allow you to transfer a part that is job controlled in the supplying warehouse.  If you create a job controlled (non-transfer) part in Part Master Maintenance, you can define the part as sourced from the supplying warehouse rather than the receiving warehouse.  You can then use the Transfer Order Maintenance conversation to enter an order for the job controlled part based on the supplying warehouse.  This transfer requisition will not have a job number, so it is not considered job-specific demand.  Any manufacturing orders or purchase requisitions created in the sourcing plant to meet transfer demand will not include a job number.  Only orders or requisitions created to meet job-specific demand will include a job number.  Thus you are supplying a job controlled part but the inventory will always be taken from common stock since there will be no job number on the transfer order. 
Note: Job-controlled parts cannot be master scheduled, because the MAC-PAC master schedule rollover process views the Tentative Master Schedule File (MS160M), which is an aggregate, non-job-specific statement of potential production.  Orders and requisitions created by the Master Schedule module will never carry or peg to a specific job, or have inventory netted against only job or group job inventory.
