Hi @keerthana219 ,
If you want to prevent a specific group from being populated in the “Assignment Group” field, even when a member of that group is selected in the “Assigned To” field, you can achieve this by using Client Scripts + Business Rules.
Create an onChange Client Script on the Incident table for the Assigned To field.
Purpose:
Detect the selected user
Check their group
Clear Assignment Group if it is restricted
Script Example:
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || !newValue) {
return;
}
var ga = new GlideAjax('CheckUserGroup');
ga.addParam('sysparm_name', 'isUserInRestrictedGroup');
ga.addParam('sysparm_user', newValue);
ga.getXMLAnswer(function(response) {
if (response == 'true') {
g_form.clearValue('assignment_group');
g_form.showFieldMsg('assignment_group',
'This group is restricted and cannot be auto-assigned.',
'error');
}
});
}
Step 2: Script Include (Client Callable)
Create a Script Include to check whether the user belongs to the restricted group.
Make sure:
“Client Callable” is checked
Script Example:
var CheckUserGroup = Class.create();
CheckUserGroup.prototype = Object.extendsObject(AbstractAjaxProcessor, {
isUserInRestrictedGroup: function () {
var userId = this.getParameter('sysparm_user');
var restrictedGroup = 'RESTRICTED_GROUP_SYS_ID'; // Replace with actual sys_id
var gr = new GlideRecord('sys_user_grmember');
gr.addQuery('user', userId);
gr.addQuery('group', restrictedGroup);
gr.query();
return gr.hasNext();
}
});
Replace RESTRICTED_GROUP_SYS_ID with the actual sys_id of the group.
Step 3: Business Rule (Before Insert/Update)
Client Scripts only work in UI.
To prevent assignment through API, imports, or scripts, add a Business Rule.
Business Rule Setup:
Table: Incident
When: Before
Insert & Update: Checked
Script Example:
(function executeRule(current, previous) {
if (!current.assigned_to) {
return;
}
var restrictedGroup = 'RESTRICTED_GROUP_SYS_ID';
var gr = new GlideRecord('sys_user_grmember');
gr.addQuery('user', current.assigned_to);
gr.addQuery('group', restrictedGroup);
gr.query();
if (gr.hasNext()) {
current.assignment_group = '';
gs.addErrorMessage('Restricted group cannot be assigned automatically.');
current.setAbortAction(true);
}
})(current, previous);
