Hi,

I'm glad you found an answer that worked for you.

I'd still recommend reviewing my reply as similar suggestions were stated.

I hope at a minimum, it was helpful. Keep in mind that if multiple solutions assisted you, you can accept more than one solution as well 🙂

Take care!

Did you add gs.info() to check if BR ran?

whether query is working fine?

try this

(function executeRule(current, previous /*null when async*/ ) {

//Checks for any Active approval and aborts the update if active
var gr = new GlideRecord('sysapproval_approver');
gr.addQuery('document_id', current.sys_id).addOrCondition('sysapproval', current.sys_id);
gr.addQuery('state', 'requested');
gr.query();
if (gr.hasNext()) {
gs.addInfoMessage("There are open approvals which must be completed before this record can be closed");
current.setAbortAction(true);
}

})(current, previous);
