Measures for End Item Substitution and Supersession

This topic lists the measures that store data for end item substitution and supersession in replenishment plans.

All measures support the Organization, Product, and Time dimensions.

The measures are a part of the Default Replenishment Planning Catalog and Incremental Replenishment Planning Default Catalog. If your replenishment plan is using other measure catalogs, ensure that you add these measures to the measure catalogs. Also, add these measures to your tables and graphs.

In a replenishment plan that's enabled for incremental planning, when a day is added to the planning horizon, these measures are populated with the null value for an item-location combination that doesn't have a change in net demand or supply.

If your items belong to a bidirectional (reciprocal) supersession chain, note the following:

• If you're using a replenishment plan to generate the forecast, then you need to use a user-defined measure catalog that contains the measures for forecasting for bidirectional supersession chains along with the measures for replenishment planning.
• If you're using a demand plan as the demand schedule, then you'll need to add the Item Revision Start Date and Item Revision End Date measures to a user-defined measure catalog along with the measures for replenishment planning. You'll need to use this measure catalog in the replenishment plan that you're using for calculating policies.

For information about the measures for forecasting for bidirectional supersession chains, see the topic titled Measures for Forecasting Using Supersession Relationships.

This table lists the measures for end item substitution and supersession:

Measure	Description
Initial Excess for Substitution	Excess quantity of the substitute item or supersession item that's initially available for substitution or supersession.
Initial Shortage for Substitution	Shortage quantity of the demanded item that can be initially met by the supply of the substitute item or by the supply of the supersession item.
Substitute Demand	Total quantity of the demanded item that's substituted by the supply of the substitute item or superseded by the supply of the supersession item.
Substitute Supply	Total supply of the substitute item or supersession item that meets the demand for the demanded item.
