How to set default assignment group for incident table only?

[Rahul63]

I have set default value of assignment group from dictionary. It is affecting globally on all the modules. So how can I set default assignment group for incident table only not affect on other?

You need to create a Dictonary override.

Scroll to the bottom of page when you added Default value & look for Related list Dictionary override & create a new one for incident table.

Refer doc link.

You want a Dictionary Override, my friend:

Open an Incident

Right-click the Assignment group field

Go to Configure Dictionary

Click New

Table: Incident

Submit

Hi Rahul,

As mentioned by Jaspal you can use that approach

Another approach would be using onLoad client script OR Display Business rule on incident table
