WITH PARENT FILTER
Applies all parent filters to the metric. All parent filters specified in visualizations, dashboards, and any metrics in which this metric is nested are applied to the calculation.
This clause can be shortened to WITH PF.
The WITH PARENT keyword is applied by default when other visualization filters are not present.
In the table below, you can see how the WITH PARENT FILTER clause affects the filtered version of the visualization.
|Definition||Visualization Filter||Metric Value|
|F1: Group = X||350|
|F1: Group = X||null|
In the third row above, the definition includes a nested metric in which parent filters are forced to be included from inside the nested metric.
- In the parent metric is the filter Group = Y.
- At the visualization level, the filter is Group = X.
- The WITH PARENT FILTER keyword means that all parent filters are applied to the metric. During evaluation, both Group = X and Group = Y are applied to the data as a logical AND. Since a data element may be associated with a single attribute value, there are no data elements that match both filters, and the result set is null.
