When creating a custom report the Summary step shows the report properties, columns, and column grouping and filtering, if applied. You can select the output format and configure the report's access permissions. Only users with unrestricted access permission can edit the report in the wizard. Users with read-only or unrestricted access can run the report. After saving the report, you can also run it or schedule it.
