New Incident_Task not associating with the Incident it was created from.

[Scott29]

When I am on the Incident form, go down to the "incident_tasks" related lists, and click the new button.

It creates a new task, but it doesn't create the relationship between the task and the incident. What do I need to do to make that relationship automatic?

t looks like when you click "New" under the Incident Tasks related list, a new task is created, but the Incident field is not automatically populated. To fix this and establish the relationship automatically, follow these steps:

Solution: Use a Business Rule or Client Script

Option 1: Business Rule (Recommended)

1. Navigate to System Definition > Business Rules.

2. Click New.

3. Configure the rule as follows:

   • Name: Auto-populate Incident Field
   • Table: Task (or incident_task if applicable)
   • Advanced:  (Check the Advanced box)

4. In the When to run section:

   • When: Before
   • Insert:  (Check this option)

5. In the Script tab, add the following script:

   if (!current.incident && current.parent) { current.incident = current.parent; }

6. Click Save or Submit.

Option 2: Client Script (For Immediate UI Update)

1. Navigate to System Definition > Client Scripts.

2. Click New.

3. Configure the script:

   • Name: Auto-fill Incident Field
   • Table: incident_task
   • Type: onLoad

4. Add this script:

   (function executeRule(current, gForm, gSNC) { var incidentSysId = gForm.getParameter('sysparm_parent'); if (incidentSysId) { gForm.setValue('incident', incidentSysId); } })(current, gForm, gSNC);

5. Click Save.

Hope this works for you.

• The Business Rule ensures the task is linked before it is inserted into the database.
• The Client Script updates the UI immediately when a new task form is opened.

Hi @Scott29 

It should display the incident number. If it doesn't, you need to add the logic to the new button, where it should map these two fields.
