Schedule Management
Automatic MDS Relieve (Shipment & Production Releif)
You can monitor your master demand schedule as customer shipments occur by utilizing the MDS relief process.
For master demand schedules, all sales order shipments relieve the appropriate schedule entries (shipment relief). For master production schedules, when you create discrete jobs, flow schedules, purchase orders, or purchase requisitions, you relieve schedule entries (production relief). If you associate a demand class with your schedule, the relief process updates those schedule entries whose demand class matches a sales order, discrete job, flow schedule, purchase order, or purchase requisition.
Shipment Relief
Oracle Master Scheduling/MRP and Supply Chain Planning relieves(updates) MDS schedule quantities when you ship sales order items. Shipment (MDS) relief prevents the duplication of demand that could result if you load sales orders into the master demand schedule, but do not relieve the master demand schedule upon shipment. Without relief, you would need to reload and replan your master schedule just before planning material requirements each time to obtain an accurate
picture of supply and demand for your independent demand items.
Shipping a sales order item relieves each MDS name for which you set the check Relieve. You set shipment relief when you define the master schedule name—before you define or load a schedule for that name. If you associate a demand class with your MDS, the shipment relief process relieves the MDS entries that correspond to the demand class associated with the sales order
Reduce MPS
You can automatically maintain your master production schedule with the auto–reduce MPS attribute you specify for the item in the item master in Oracle Inventory. For each item, you can specify a point in time after which you no longer want the item to appear on the MPS. This point in time can be the demand time fence, the planning time fence, or the current date depending on your business practices.
Production Relief
Oracle Master Scheduling/MRP and Supply Chain Planning relieves (updates) MPS schedule quantities when you create purchase orders, purchase requisitions or discrete jobs—whether you define the purchase requisitions or jobs manually or load them with the Planner Workbench.
Production (MPS) relief prevents the duplication of supply. Without relief, you would need to replan your master schedule just before planning material requirements each time to obtain an accurate picture of supply and demand for your MPS planned items. Creating a purchase order, purchase requisition, or discrete job relieves each MPS name for which you check Relieve. You set production relief when you define the master schedule name—before you enter or load a schedule for that name. If you associate a demand class with your MPS, the production relief process relieves the MPS entries that correspond to the demand class associated with the discrete job.
Planning Manager and Schedule Relief
The Planning Manager is the background process that manages shipment and production relief.
For shipment relief, the Planning Manager first looks for the specific sales order entry to find a specific schedule entry to relieve. If it does not find an entry for that exact sales order date, the Planning Manager begins at the oldest schedule entry for the item and moves forward in time, decrementing schedule entry quantities until is reaches the sales order shipment quantity.
For example, suppose you have MDS entries of 10 each on Monday, Tuesday, and Wednesday. If you ship a sales order for 25 on Tuesday, the relief process deducts 10 on Tuesday (leaving 0), deducts 10 on Monday (leaving 0), and deducts the remaining 5 on Wednesday (leaving 5). Thus, the new master schedule entries are quantity 0, 0, and 5 on Monday, Tuesday, and Wednesday, respectively.
For production relief, the Planning Manager first looks at the discrete job due date to find an MPS schedule entry to relieve. It then looks backward, up to the first schedule entry, and then forward until it finds enough schedule quantity to relieve.
For example, suppose you have MPS entries of 10 each on Monday, Tuesday, and Wednesday and you specify the MRP: MPS Relief Direction profile option as Backward, then forward. If you create a discrete job for 25 on Tuesday, the relief process deducts 10 on Tuesday (leaving 0), deducts 10 on Monday (leaving 0), and deducts the remaining 5 on Wednesday (leaving 5). Thus, the new master schedule entries are quantity 0, 0, and 5 on Monday, Tuesday, and Wednesday,
respectively.
Master Scheduling by Demand Class
You can optionally associate a demand class to a master demand schedule or master production schedule when you define the master schedule name. When you ship a sales order or create a discrete job, that sales order or discrete job relieves the master schedules that are associated with the demand class of the sales order or discrete job. You can load a subset of the sales orders into your master schedule for a specific demand class.
MPS Explosion Level
For MDS entries, this defines the lowest level at which an MPS planned part appears in the bill of material structure for the item. When you generate an MPS plan, the process does not explode beyond this level. This reduces MPS processing time.
The default value comes from the Max Bill Levels field in the Bill of Materials Parameters window. Enter a value in the Master Demand Schedule Items window to override the default. This value must be an integer and cannot be greater than 60.
Attention: You should be extremely cautious when entering a value here. If you are unsure of the lowest level that an MPS part exists, use the default value. The explosion process explodes through the entire bill of material.
Excellent Material!
