Ratio calculation rule
The default ratio configuration uses Number of activities or Number of cases and COUNT as the aggregation for the measure values. The calculation rule calculates the ratio of the number of cases or activities with a specific configured value relative to all cases or activities. The format of measures that use the RATIO aggregation is automatically set to Percentage.
The result for the ratio is always calculated within the scope of the dimensions added to the analysis. You can add the dimensions to the Configuration panel. For details on adding dimensions to an analysis, see the chapter Use the App builder.
The following figure shows the ratio calculation rule for the selected Product category measure. The numerator calculates the number of cases that belong to the Raw materials product category. The denominator calculates the total number of cases.
The following examples help you to get familiar with the configuration of the ratio aggregation of a measure.
