There is no possible way to clear the related list by using a UI action on the current form. If you don’t like the related list to be displayed on the form you can remove these lists by configuring the related lists or by creating a button on the related list that will display the records that you need.

If it’s a UI action running a client script (as this would need to be) then you need to use the ‘onclick’, and ‘client’ fields. You would also need to wrap the ‘try/catch’ block in a function which would need to be called from the ‘onclick’ field by its function name. You can look at other UI actions in the system that have the ‘Client’ field marked as true to see some examples of how this would be done.

Cancel that. I used the name, not label. I read through the instructions too fast previously. Either way, it’s still not functioning properly for me.

I’m attempting your embedded list script and not having any luck. Does it still require the onclick, client, and condition? I would assume not. I have given my relationship a label and replaced the “Affected CIs” with it, but it still refreshes the entire page, instead of just the embedded list. Ideas?

Can you disable/remove status options from a list? Lets say I want to remove the close status from the incident list without using ACLs.

There’s a lot more to your script than a simple list refresh. I’ve confirmed that the embedded list refresh works fine in a SN demo environment so I know that’s not the problem here. The only thing I can suggest is to break your script down into more basic sections so you can see where the conflict is. You should probably start with a basic action-invoked refresh and then work up from there.

This question is more of a general ServiceNow configuration question so you should probably ask this on the ServiceNow community site.

Thanks for all the tips you provide, it is very helpful.

I have a requirement where the Affected Group needs to be embedded to our Change Request form. When the user click on “Request for Approval” UI Action, it will check if there are Affected Groups. If none, it will open a slushbucket (which is also from your site: https://servicenowguru.com/system-ui/ui-actions-system-ui/creating-custom-slushbucket-popup-dialog/). I tried to do the code above on refreshing embedded related list, could not get it to work. How does the code for refreshing embedded related list work? Below is the UI Action code. Any help is greatly appreciated.

function requestApproval() {
	if (g_form.getValue('assigned_to') == '') {
		try {g_form.hideFieldMsg('assigned_to');} catch(e1) {}
		g_form.setMandatory('assigned_to', true);
		g_form.showFieldMsg('assigned_to','Assigned to is required when requesting approval','error');
		return false;  //Abort submission
	}
	var affectedGrp = new GlideRecord('task_group');
	affectedGrp.addQuery('task', g_form.getUniqueValue());
	affectedGrp.query();
	if (!affectedGrp.next()) {
		if (g_form.modified) {
			gsftSubmit(null, g_form.getFormElement(), 'sysverb_update_and_stay');
			gsftSubmit(null, g_form.getFormElement(), 'request.approval'); //MUST call the 'Action name' set in this UI Action
		}
		var dialog = new GlideDialogWindow('affected_groups');
		dialog.setTitle('Affected Group');
		dialog.setPreference('sysparm_groupQuery', 'source=change_request');
		dialog.render();
		try {
			var elementLookup = $$('div.tabs2_list');
			var listName = "Groups affected";
			alert('elementLookup: ' + elementLookup);
			for (i = 0; i < elementLookup.length; i++) {
				if (elementLookup[i].innerHTML.indexOf(listName) != -1) {
					var listHTML = elementLookup[i].id.split('_');
					var listID = listHTML[0];
					alert('listID: ' + listID);
					nowRefresh(listID);
				}
			}
			
			function nowRefresh(id) {
				GlideList2.get(id).refresh('');
			}
		}
		catch (err) {}
		// gsftSubmit(null, g_form.getFormElement(), 'request.approval'); //MUST call the 'Action name' set in this UI Action
		return false;
	}
	
	//Call the UI Action and skip the 'onclick' function
	gsftSubmit(null, g_form.getFormElement(), 'request.approval'); //MUST call the 'Action name' set in this UI Action
	
}

if (typeof window == 'undefined')
	requestForApproval();

function requestForApproval(){
	current.approval='requested';
	current.state = -5;
	current.update();
	action.setRedirectURL(current);
}

I have another question, which I know is basic: How do I pass multiple variables to an extended table?

I have “Cards” for time cards, and I have “Time” to record actual time (Extention of CARD). On the CARD, end users record the reporting period, HR hours recorded (to calculate against) and that is basicially it. The other fields are auto-filled.

Each Time entry has many more fields, but also need to include the name of the person on the CARD (in case the manager is filling it out) as well as the timeframe. Both of these are lookup fields, and exist on CARD. I have tried everything I can think of, and everything I can find, but I’m not having any luck.

Could you point me in the right direction? In general, I have not had good luck with passing variables anywhere in SN — I did some workflows a few weeks ago that I FINALLY got to work, but it took a lot of doing.

Thank you again for your feedback!
