Before you enter details of a master schedule manually or load a schedule from another source, you first define a name. You can also set several options for each name.

Defining MDS
Enter a name, description, demand class and enable relieve if required.

Defining MPS
Enter a name, description & demand class.

1. Check Relieve to relieve schedule entries.
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.
2. In the MPS window check Inventory ATP. You can optionally include your MPS plan as available supply when you calculate
available to promise information in Oracle Inventory.
3. In the MPS window, check Production to enable a plan to auto–release planned orders.
4. In the MPS window, check Feedback to monitor the quantity of the planned order that has been implemented as discrete jobs, purchase orders, or purchase requisitions. This provides the planner visibility of the status of the plan at any point in time.

Defining Schedule Entries Manually
A schedule entry is a unique relationship between an item, date, and quantity on a master schedule. You define schedule entries by adding items to schedule names, then defining detailed date and quantity information for each item.

Enter an item with an MRP planning method of MPS Planning. Enter a different MPS explosion level, if you want to change the default. Choose Detail to open the Master Demand Schedule Entries window or Master Production Schedule Entries window.

1. Enter a date. For MDS, this is the date of shipment. For an MPS, this is the completion date of production. For repetitive items, whether MDS or MPS, this is the start date of production.
2. For repetitive items, enter an end date of production.
3. Enter a current quantity.
This also becomes the original quantity and the total. Schedule reliefs reduce the current quantity. Schedule reliefs plus the current quantity equals the total.
4. Check Reliefs if you want this entry to be decremented 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.
