Scenario: Line A has a demand of 500 parts for the week, but only 450 parts are produced. The pace at the end of the week is -50. Customer demand hasn't changed, so Line A must build 50 extra parts the next week. Fortunately, there are a few ways to carry the demand forward.
Option One: Carry Over
Carry over the previous week's deficit forward into the current week. This is done by enabling the "Carry over the previous week Pace metric" setting in the Production Module Settings screen. When enabled, the previous week's past due pace (Actual - Demand) will be included in the demand of the current week. When the above setting is enabled, the Demand, Pace, and Pitch Pace metrics will be modified on the Operator Portal, Pitch Board, Production Status by Line dashboard, and the Production Status by Area dashboard.
The "Carry over the previous week Pace metric" setting affects all lines for a site.
Note: If you're calculating PEFF and other metrics that use demand in the equation from the operator portal, pitch boards and week summary page, you must remember that these do not account for the previous week's past due added.
In the example above, the week's demand shows 2589, however, the pace carried over was 400.
To look at PEFF you must subtract the 400 from 2589 then do the PEFF calculation to get the 91% PEFF as shown in the example above.
Option Two: Pace Start Date
A single Line's pace can be "reset" by a specific date. This is done by setting a date in the "Pace Start Date" setting each individual line. It can also be set from the Production Pitch Schedule page under "More > Line Pace Date."
When the Pace Start Date is set, the Demand metric will include all past due parts up until the Pace Start Date, and the Pace, and Pitch Pace metrics will be calculated using the new Demand value. This takes effect on the Operator Portal, Pitch Board, Production Status by Line dashboard, and the Production Status by Area dashboard.
When the pace start date is set, the production setting "Carry over the previous week Pace metric" setting is ignored for the Line. It is possible to have a mix where some lines are using the Line's Pace Start Date and other lines are using the Production "Carry over the previous week Pace metric" setting.
If a Line has a Pace Start Date set, up to 3 months' worth of weekly past due demand will be carried over. Most often, planners will reconcile product orders more often than every 3 months
