  2. Select the incident you want to update together with the value.

Run a script

Select a script to run on the incoming incident. When you create a script, you need to add the preProcessing tag for the script to appear in the list of available scripts.

Note

Pre-Process rules that use system-based scripts such as GetIncidentsByQuery, by default, are run according to the defined role (Limited User). For example, if the GetIncidentsByQuery script runs with the Limited User role, it also runs with the Limited User role in the Pre-Process rule. You can change the default by either detaching the script and updating the RunAs field such as DbotRole, or create a wrapper script with the required role set in the RunAs field. The wrapper script calls the system-based script. The system-based when called by the wrapper scriptruns with the role assigned to the wrapper script.

Pre-processing scripts can access sensitive incident data. As best practice, we recommend assigning a Role for the pre-processing script to allow only trusted users to edit it.

Choose a script

From the dropdown list, select the script to run on the incoming incident. Only scripts that were tagged preProcessing appear in the drop-down list.
