Percentage Growth (OLAP) 
Purpose
The Percentage Growth template is an OLAP variance template with which you can build queries that calculate the percentage by which a specific measure has increased or decreased for a selected member in comparison to the same period of time previously or subsequently.
This template is similar to the Rank Change template, but it doesn't perform a Top N calculation to select the members of the base period (and the results are expressed as a percentage).
You should use this template if you would like to address business questions such as the following:
By what percentage did my sales increase this year compared to last year?
Prerequisites
You have an OLAP data service configured as a BI system.
Process Flow
After using the BI Query Wizard to select an OLAP data service and the Percentage Growth template, the wizard steps you through the following process flow:
...
2. Configure Percentage Growth parameters
Result
After you have completed the wizard screens according to the process above and clicked Finish, you return to the Visual Composer workspace, where a new data service has been created with the query you have configured.
A data service created with the BI Query Wizard is configured automatically with a start input and a table view as output. These three elements together constitute a complete iView, ready for preview and deployment to your portal.
To continue working with your data service and query, see:
