Production IDs and Production Schedules Using PeopleSoft Supply Planning

PeopleSoft Supply Planning analyzes supply and demand and determines whether new planned production needs to be generated. If new production is required, the system generates a planning message to recommend creation of a new production ID or production schedule. When a planned manufacturing order is generated within PeopleSoft Supply Planning, it is always backward scheduled based on the required delivery date and the routing or item's lead times to determine the start date of production.

If you are using the PeopleSoft Supply Planning solvers to schedule and reschedule production:

• Freeze production within PeopleSoft Supply Planning and apply the frozen requirement to the production within PeopleSoft Manufacturing.

  For example, PeopleSoft Supply Planning sends a planning message for a new production ID back to PeopleSoft Manufacturing with the requirement that production is frozen.

• Using PeopleSoft Manufacturing, convert the recommendation into a production ID with an Entered, Firmed, or Released status.

  If you are using the Production ID Maintenance component to change any information on the production ID that affects scheduling, the system displays a warning message that indicates production is frozen and any of the changes result in rescheduling the production. You can override the frozen status by proceeding and changing the information, or you can cancel the changes.

Within PeopleSoft Manufacturing, you can manually freeze production. Do this by selecting Frozen Production on the Planning Attribute page for production IDs or by selecting the Frozen check box on the Production by Area Details page for production schedules.

PeopleSoft Supply Planning uses planning lead times or routing times when scheduling production, and it takes into account the following factors that affect the actual start date and time and actual due date and time of each operation:

• Capacity and material availability.

• Planning labor or machine setup, run, and fixed run times or run rates.

• Operation overlap, based on an overlap percentage or send-ahead quantity.

• Operation intensity, based on machine, labor, cumulative, or longest.

• Operation yield.

• The work center calendar, if one exists.

• The production calendar, if one exists.

• The five-day work week calendar, when no other calendar exists.

Reviewing, Approving, and Applying Production Messages

Once a plan has been created and recommendations are made, planning messages are returned to the transactional system using the Post Updates process (PL_POST). Once the messages are received, you can:

• Review and approve the production messages using the Approve Production Updates component.

  Use this component to select the messages that you want to review, then look at the production details, status details, and configuration code information to select which messages you want to approve.

• Review any exception messages generated when the production messages are applied by using the Review Post Errors component.

  Use this component to select the exceptions that you want to review, then look at the exception details, dates and quantities, and configuration code information.

• Apply the production messages to PeopleSoft Manufacturing to take action on the recommendations made by PeopleSoft Supply Planning by using the Apply Production Updates page.
