Past Due Demands

You can specify parameters to include past-due demands within a supply plan or a demand and supply plan by using plan option values instead of the supply network model.

Configure the past due demands parameters on the Plan Options page, Supply tab, Forecast Allocation and Consumption subtab.

Parameter	Description
Source for Including Past Due Demands	Indicates the source to determine whether to include past due demands in the plan. Source options are: Plan option values: If selected, then the values specified in the past due demand section of plan options are used instead of the past due values found within the supply network model. The past due demands plan options in this section apply to all organizations included in the plan's scope. The values found in the supply network model can vary by organization. Supply network model: If selected, then the past due values found in the supply network model is used to determine what past due demands are copied into the plan.
Past Due Demand Calendar	Calendar to use to determine which past due demands to include in the plan. The type of calendar selected determines the list of values for Past Due Demand Bucket Type. If the past due demand calendar is a Gregorian calendar, the past due demand bucket type list of values includes only Day and Month. But if the past due demand calendar isn't a Gregorian calendar, then the past due demand bucket type list of values includes Day, Week, and Period.
Past Due Demand Bucket Type	The level of time, such as day, week, or month, to use to determine whether to include a past due demand in a plan.
Past Due Open Sales Order Buckets	Number of time buckets, such as three weeks or two months. Determines how much earlier than the plan start date to use as a threshold for copying past due open sales orders into a plan.
Past Due Shipped Sales Order Buckets	Number of time buckets, such as three weeks or two months. Determines how much earlier than the plan start date to use as a threshold for copying past due shipped sales orders into a plan.
Past Due Forecast Buckets	Number of time buckets, such as three weeks or two months. Determines how much earlier than the plan start date to use as a threshold for copying past due forecasts into a plan. The planning process aggregates all of the forecasts within the past due dates of the plan and places the result at the plan start.

Understanding Past Due Demands When Forecast Is in Aggregate Buckets

When the forecast is at a higher level than day, you might see past due forecasts in your plan that are earlier than expected.

For example, let’s say you’ve specified in the Past Due Demand section of plan options that the plan should include zero past due forecast buckets. If your forecast is at a higher level than day, the entire forecast of the current forecast bucket is copied into the plan. If the plan start date is a Wednesday, that means the entire week’s forecast is copied into the plan.

You can eliminate including Monday’s and Tuesday’s forecast in the plan by doing both of the following:

• Select the Demand time fence control check box on the Supply tab, General subtab, in plan options.
• Set the item’s Demand Time Fence Days to zero.

When the Demand time fence control plan option is turned on in the plan, planning doesn’t consider forecast entries within the demand time fence as demand.

If you want Monday’s and Tuesday’s forecast to be used in forecast consumption and then drop the remaining unconsumed forecast, select the Consume forecast inside demand time fence check box. This check box is located on the Supply tab, Forecast and Allocation subtab, in plan options.
