Hi @mumashankar 

In ServiceNow dependent choice filtering works on forms but not in list views or report filter dropdowns so you can't hide impact choices by category in the list editor out of the box.
To enforce the dependency use a Before Business Rule or Data Policy to block invalid combinations on save or disable list edit for the impact field and require editing on the form.

not possible to show/hide options in list view

Better approach

1) restrict list edit using list_edit ACL for that field and ensure users update only via form

OR

2) use before update BR to validate if user selected correct impact value based on category, if not then abort the update

Hi @mumashankar 

Since list views are optimized for rapid data access, they do not support dynamic client-side choice filtering (for example, via UI Policies).

To prevent field updates or conditionally restrict available choices in a list, implement the logic using server-side controls and cell-editing scripts.

Either you can

1)Hide Choices in the Form View 

OR 

2)Prevent List View Updates  by onCellEdit Script

Sample script:

function onCellEdit(sysIDs, table, olds, news, callback) {
var newValue = news;
var impactVal = parseInt(newValue, 10);

if (g_form.getValue('category') == 'software' && impactVal == 1) {
alert("You cannot set this Impact value for the Software category from the list view.");
callback(false);
} else {
callback(true);
}
}
