Output

The Output has two different functions, based on the status of the report:
Draft
When a report is in the draft mode, the Output allows you to format the display of tables, and define a multi-chart canvas if required.
Active
When a report is in the active mode, the Output allows you to report action. Based on role permissions, a report also provides the option for appropriate users to place the report back into draft mode and edit various components. Report actions include exporting, sharing, and broadcasting the report.

Go to Create > Report > Output.
