Define breakdown by grouped values
If you click Grouped Values in the Breakdown Details window, the report will include a column or row for every group that you define. This option results in a static list of breakdown values that does not automatically adjust to changing source data.
Note:
If there are more than 20,000 available values for the breakdown variable, you cannot use a breakdown by grouped values.Note:
You cannot save the report definition if all groups are empty (that is, have no values in them). If some groups are empty, the report definition is saved and the empty groups are ignored.Parent topic: Specify variable breakdowns
