How to make fields mandatory in list view

[kambleneeta20]

Hi Experts,

I want to make "Assigned To" Field mandatory in list view in state "In Use" , is there any way to add "Assigned To" field in below State and Substate in list view ?

Thank you.

Please see following client script.  Let me if you have any question.

The following is a simple approach

I tried this for the "Assignment group" field of the Incidents List View, but it works partially;

- With this Client Script activated, you cannot leave the "Assignment group" field empty.
- But.. you also cannot do any other input and this last detail is a big one, a big issue. 

How can I solve this?

My Client Script details:
- Table = Incident
- UI Type = Desktop
- Type = onCellEdit
- Field name = Assignment group
- Script:

function onCellEdit(sysIDs, table, oldValues, newValue, callback) {
var saveAndClose = true;

//Type appropriate comment here, and begin script below
g_form.setMandatory('assignment_group', true);

callback(saveAndClose);
}
