# Perform the Report View Assessment scan

# Perform the Report View Assessment scan {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Scan your instance for data visualizations and Core UI reports that users were stopped from viewing based on existing access control lists (ACLs).

## Before you begin

Roles required: admin and security_admin.

## About this task

The assessment scan returns a list of affected data visualizations and Core UI reports. A visualization or report is affected if a user who lacks access has attempted to view it. Access is determined by a report_view ACL or, for visualizations of tables without report_view ACLs,
by a read ACL.

The time the assessment scan takes can vary according to the number of records in the instance. Consider running the assessment overnight. Also consider filtering the reports that the assessment applies to. For more information,
see [Filter report assessment scans](https://www.servicenow.com/docs/5DRVVfl42fcaDivrnJugpg#filter-report-assessment-scans "Especially on large instances, the ACL Assessment for Data Visualizations can take a long time. To reduce the assessment time, you can use system properties to filter the reports that the assessment applies to.").

## Procedure

1. Elevate your role to security_admin.  
   For more information, see [Elevate to a privileged
   role](https://www.servicenow.com/docs/access?context=t_ElevateToAPrivilegedRole&version=australia&pubname=australia-platform-security&ft:locale=en-US).
2. Navigate to AllPlatform Analytics AdministrationACL Assessment for Data VisualizationsACL Dashboard.
3. Select Run Assessment Scan.  
   The assessment scan can take a long time on instances with many reports. You can choose to view partial results while the scan is in progress, or select View Result when the scan is complete. When the scan is complete, a message shows who ran the assessment and the start and stop time of the assessment.  
   Note:  
   The scan calculates the number of executions of each affected report.  
   The initial scan shows:
   * The user who executed the scan and the scan's start and end times
   * The number of affected reports
   * The percent of reports on the instance that are affected
   * The number of tables with report_view access control lists
   {#perform-report-view-acl-assessment-scan__ul_oz5_wnc_vpb}
4. **Optional:** If the affected reports list is empty, navigate to report_executions.list.
   1. If this table is empty, there are no ACL issues.
   2. If the report_executions.list has entries, change the system property sn_report_acl.run_scan_based_on_report_execution_only to false and run the scan again.  
      This time, the scan shows all the affected reports, not only those reports that have been executed. The second scan often takes longer to run.
5. Navigate to AllPlatform Analytics AdministrationACL Assessment for Data VisualizationsAffected Data Visualizations to [view the list of impacted reports](https://www.servicenow.com/docs/4xC5JVapm1Vi_HKyJSsKZA "The Report view ACL assessments table shows the impacted data visualizations and Core UI reports identified by the ACL Assessment for Data Visualizations. Use this list to remediate affected visualizations and users.").  
   The Report view ACL assessments list shows the visualizations with attempted views affected by ACLs.
