Incident Reference Number not automatically displaying on task form

[nicolaosoteo]

Hi,

I am very new to servicenow, this might be very obvious but can somebody please help me with the below?

On a customer's incident task field, they have a reference field to an incident. They want the incident number to be automatically shown when clicking 'incident task' from the incident form related list. So far, there is no value whatsoever being shown. I have checked the 'display' rules, and I can see the relevant fields showing true, can I please be shown what I am missing here?

Display rule seems true

Incident task form

Display Rule seems correct

Thank you in advance

This is probably your issue. Follow the steps below but set to false.

5 Preventing Numbering Gaps

By default, numbers are generated every time a new record is created. When records are created but not saved, a gap in the numbering is created. To generate numbers only when records are saved, navigate to System Properties > System and set the property Assign a task number only upon insert (prevents unused numbers) to true.

Hi Nicola,

As you are trying to display incident number on incident_task table so you need to make changes on 'incident_task' table.

In incident_task table either display value of all column should be false then by default incident number will be shown there or you can set display   to true only for incident column.
