Late Demand Analysis View

As a supply planner, you want to readily understand which supply is the root cause for a demand that is at risk of fulfilling late in a multilevel supply chain with a complex bill of material. Access the Late Demand Analysis table to identify the supplies at any level of the bill of material that are causing an end demand to be at risk of being late.

Note: You must be opted in to the feature named Constraint-Based Planning to access the Late Demand Analysis table.

Constrained supply plans consider lead times as a hard constraint while resource or supplier capacity can be overloaded. A plan can have late demand satisfaction due to lead time or time fence constraints. The Late Demand Analysis table enables you to pinpoint the components or subassemblies that are the root cause of demands being at risk. You can then choose specific activities to resolve the issues. You can’t edit the data in the Late Demand Analysis table. However, you can edit the data elsewhere, such as in the Supplies and Demands table or a simulation set. For example, you can select an alternate shipment method to expedite the supplies causing the lateness. After you make changes, rerun the supply plan to check if demands are satisfied on time.

To access the Late Demand Analysis table from an open constrained supply plan, open the Open Table, Graph, or Tile Set dialog box and search for the table. You can also drill to the Late Demand Analysis table to analyze late end demand from the following tables after selecting one or more end demands:

  • Build Plan
  • Exceptions
  • Material Plan
  • Supplies and Demands

You can also drill from the following exception reports to the Late Demand Analysis table:

  • Late Replenishment for Sales Order
  • Late Replenishment for Forecast
  • Late Supply Pegged to Sales Order
  • Late Supply Pegged to Forecast
  • Demand at Risk Due to Insufficient Lead Time

The Late Demand Analysis table displays the supply pegging chain of only those components or subassemblies that are causing demand to satisfy late. The table displays the constrained supply path when one or more selected end demands are satisfied late. However, the table won’t display all pegged supplies to the end demand. Additional calculated attributes, such as slack days, are available to further understand the degree of flexibility for manual changes to the plan.

When you access the Late Demand Analysis table, select a Late Demand Analysis Type in the Search section to search for constrained supplies to analyze any late demands:

  • All supply paths causing late demand: When selected, the table displays the pegging chain of all potential supplies that might cause end demands to satisfy late.
  • Most constrained supply path: When selected, the table displays the supply pegging chain that’s caused the maximum delay to an end demand.

The following table describes some of the columns in the Late Demand Analysis table:

Column Header Description
Assembly Item Assembly item name for the end demand.
Component Item Subassembly or component of finished good present in the constrained supply plan.
Component Supply Organization Organization of the assembly or component supply.
Due Date of End Demand Due date of end demands such as sales order, forecast, and manual demand.
Earliest Start Date Earliest date on which the supply can start.
End Demand Value Value of the end demand.
Latest Start Date for Pegged Supply Latest date when the pegged supply should have been started to complete demand on time.
Level Pegging level of assembly or components. The level for the end item is 0 (zero). The end item’s immediate component is level 1, and so on.
Need-by Date Date on which the supply should be complete in order to meet the demand on time.
Number of Occurrences Number of occurrences of a particular supply record for a subassembly or component in the selected search.
Order Number Order number of pegged supply.
Order Number for End Supply Order number of the supply pegged to end demand in constrained supply path.
Order Quantity Order quantity of late supply pegged to demand.
Order Type Order type of supplies present in constrained supply path.
Order Type for End Demand End demand’s order type, such as sales order, forecast, and so on.
Organization Organization for the end demand.
Shared Supply If Yes, the supply is consumed by multiple demands; if No, then the supply isn’t consumed by multiple demands.
Slack Days The number of days between the earliest start date and the latest start date for pegged supply. The supply planning process calculates this number.
Suggested Due Date Suggested due date of pegged supply.
