What is Demand Aggregation? How is it enabled and used?

Demand Aggregation enables you to consolidate line items from one or more purchase requisitions (PR) into a single aggregated requisition. This allows you to combine spend to take advantage of better tier pricing and more flexible sourcing.

To enable:

• Support can set Application.Purchasing.EnableDemandAggregation to Yes
• A Customer Administrator must configure demand holding rules using the Import Demand Holding Rules.
• Users must be added to the Purchasing Agent and Purchasing Manager groups.
• For generic Enterprise Resource Planning (ERP) systems, one or more Purchasing Agents must be assigned as responsible users for each Purchasing Unit.
• A member of the Integration Admin group must refer to the Data Dictionary and use Core Administration > Integration Manager > Data Definitions to review and accept the data definition changes.

To use:

1. As requisitions are created, they will compared to the Demand Holding Rules. If there is no match, the PR is handled as per normal process.
2. If a match is found, the lines are held for aggregation as per the matched Holding Rule
   1. For Holding Rules with auto-aggregation, held lines will be moved to an aggregated PR by the Auto-Aggregate Held Line Items scheduled task.
   2. For all other Holding Rules, lines are added to the Purchasing Workbench.
3. Purchasing Agents use Manage > Purchasing Workbench to manually select held lines and move to an aggregated PR.
4. The new aggregated PR moves through the procurement process in the same way a normal PR would.
5. A PR in which all lines were held for aggregation will remain in Approved status.
