# Execute a reactive scan

# Execute a reactive scan {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Execute a reactive scan to set up a scan that runs automatically on an execution
tracker failure.

## Before you begin

Role required: admin.

## About this task

For many failed processes on your instance, you can find a corresponding record on the execution tracker. The progress window shows the status of the test. If a process fails on an execution tracker, Instance Scan can watch for that failure on the progress status and run a scan automatically.

The Trigger Type in the Scan Trigger form should match the Source Table field on the sys_execution_tracker record of the failed
process to enable the connection between the two. For example, if the failed test is
in the Update Sets list, you can set up the Trigger Type as
sys_update_set. This enables Instance Scan to be connected to the execution tracker
test failure.

## Procedure

1. Enter <kbd class="ph userinput">scan_trigger_list.do</kbd> in the navigation filter.  
   A list of scan triggers shows up.
2. Select the required trigger from the list to update it.  
   Note:  
   The Trigger Type is based off of table names. You can also create a custom trigger type in your codes.  
   The reactive scan is now set up to automatically scan the execution tracker of the failed process which appears on the scan results table.
