Add an additional group by or stack by – Report Designer

You can configure a report to let users adjust its grouping and stacking.

Before you begin

Role required: itil, report_user

About this task

Configure alternative Group by and Stack by choices that users can select when viewing the chart. Additional group bys can be added to any report that supports group bys (such as bar or pie) and to list reports as columns. When you configure an additional group by to a bar or horizontal bar, it is also added as an additional stack by. You can add variables and variable groups as additional group bys.

Note: Available Stack by fields are limited to catalog variables, reference fields, choice lists, and boolean values. Date/time, integer, long, string, list, and text fields cannot be used as stacked fields.


  1. Navigate to Reports > View / Run.
  2. Select a report.
  3. On the Configure tab, click Additional group by.
  4. Move one or more fields to the Selected list.
  5. (Optional) Select a Stack by field used to show the relationship of individual items from the selected field to the whole. For example, group a bar chart of incidents by Category and stack by Priority. The viewer can then determine at a glance the proportion of high, medium, and low priority issues for each category.
    Users viewing the report can select one of these fields to group or stack the report data. The report Group by and Stack by field values are the default choices.
    Note: Only bar and horizontal bar reports use stacked data. Other report types allow only grouping.
  6. Arrange the fields in the Selected column in the order you want them to appear to users.
  7. Click Close.
  8. In the report builder, click Save.
