# Manage visualizations with ACLs on extended fields

# Manage visualizations with ACLs on extended fields {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Add a system property to identify data visualizations and Core UI reports affected by report_view ACLs on dot-walked fields.

## Before you begin

Role required: admin and security_admin.

## Procedure

1. Create the system property sn_report_acl.com.par_report_acl_assessment.collect_dotwalk and set it to <kbd class="ph userinput">true</kbd>.  
   For more information on creating system properties, see [Add a system property](https://www.servicenow.com/docs/access?context=t_AddAPropertyUsingSysPropsList&version=brazil&pubname=brazil-platform-administration&ft:locale=en-US).
2. [Perform the Report View Assessment scan](https://www.servicenow.com/docs/NXpRyRSei28ewkzX4sueFg "Scan your instance for data visualizations and Core UI reports that users were stopped from viewing based on existing access control lists (ACLs).").

## Result

The Affected Data Visualizations list has a new column, Dot walk fields. This column is visible only when an affected report is identified based on an ACL on a field on an extended table.
