You can use mathematical formulas to calculate KPI values on:
- Manually saved home page tiles
- Graphical cards across all card views, including:
- Card view visualization in list views
- General Overview
This feature allows you to apply arithmetical operators (such as +, -, *, /) and simple numeric functions. The measure fields you select from the data source of a card or tile act as variables within your formula.
In the following video, Adele, a sales manager at OEC computers will show you how she:
- Adds a card to the General Overview that sums up the sales filtered for the current year by using the A/R Invoices data source filtered by Posting Date = this year.
- Adds a KPI to this card that shows the open balance for these invoices by adding a formula KPI that subtracts the invoices Paid Sum from the Document Total.

To learn more about KPI details refer to the ‘Add a card’ section in Card View | SAP Help Portal.
