Aggregate Views Overview

Aggregate Views Overview

Aggregate views allow you to view and validate data aggregations, such as averages, sums, or counts on groups of data. The aggregations are calculated and grouped in the target tables, but exist as single transactions or rows in sources. To validate the data aggregations in the sources against the data in targets, you can use aggregate views.
You can use Data Validation Option sources, lookup views, SQL views, and join views as sources in an aggregate view.
The following are some examples where you might want to use aggregate views:
  • you want to pre-calculate aggregated sales data for each sales region.
  • you want to calculate aggregated salaries for each department in an organization.
