Query on Client Script

[vodnalar26]

Hello Everyone,

I am facing an issue related to impersonation and field behavior in ServiceNow.

I wrote a Client Script where, if a specific user is impersonated, the Assignment Group field should become read-only; otherwise, it should remain editable.

The logic is working correctly for other fields, and even the setMandatory() functionality works as expected. However, setReadOnly() is not working specifically for the Assignment Group field.

I verified that:

• The script is executing properly

• The impersonated user is being identified correctly using g_user.userID

• The same logic works on fields like short_description and category

But for assignment_group, the field still remains editable.

Could anyone please help me understand:

• Is there any restriction specific to the assignment_group field?

• Could a UI Policy, ACL, or dictionary configuration be overriding the Client Script behavior?

• What would be the best approach to make assignment_group read-only during impersonation?

• here I have uploaded my code

Any guidance would be greatly appreciated.

Thank you.

Hi @vodnalar26 ,

A field can be set readonly only if it is not mandatory.

If this field is mandatory then call g_form.setMandatory('assignment_group',false) before setting readonly.

Ok, I just checked it. The script was initially working with the setMandatory() method. Later, I changed the script method from setMandatory() to setReadOnly(), and after that, the issue started occurring specifically for the Assignment Group field.

Hi,

Your script should be like below (both statement should be present):

g_form.setMandatory('assignment_group',false);

g_form.setReadOnly('assignment_group',true);
