clear out field value

[dev_K]

Hi!

I would like to make sure that if user changes >>assignment group<< to a different one, the >>Assigned to<< field is cleared out. Like this we are sure that only ppl from the assignment group can be assigned to the task.

Shall I use business rule to solve this?

thanks!

Hi @dev_K

If you make the assigned_to field dependen of assignment group, if you change the group and the assigned-to is not in that groups it is automatically cleared. No need of scripts, BR, and so on.

how I can make assigned_to field dependent on the assignment_group?

Go to configure dictionary of Assigned to and check

Hi @dev_K ,

I checked there is one OOB client script working on assignment group works on ONLOAD Firstly you can check your instance if this client script present or not, if not you can add that name "Empty assigned_to on group change"

You can create one client script and add below code 

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
	if (isLoading)
		return;

	// Need to get the form value, in case it changes but then changes back to value in database (oldValue is always DB value)
	if (oldValue != newValue)
		g_scratchpad.formValue = newValue;

	if (newValue === '' || newValue == null || oldValue != newValue || newValue != g_scratchpad.formValue) {
		if(newValue && g_form.getValue("assigned_to")){
			var groupLookupGr = new GlideRecord('sys_user_grmember');
			groupLookupGr.addQuery('group.sys_id', newValue);
			groupLookupGr.addQuery('user', g_form.getValue("assigned_to"));
			groupLookupGr.setLimit(1);
			groupLookupGr.query(groupLookupCallback);
		} else {
			g_form.setValue("assigned_to", "");
		}
	}
}

function groupLookupCallback(groupLookupGr){
	if (!groupLookupGr.hasNext())
		g_form.setValue("assigned_to", "");
}
