Hi Amit,

you cannot use action in business rule; only allowed is gs object for redirection

you cannot open the page in new tab using gs.setRedirect(url)

To which page you need to take

sample below

gs.setRedirect('/incident.do?sys_id=-1'); // this will take to new incident record

Mark ✅ Correct if this solves your issue and also mark 👍 Helpful if you find my response worthy based on the impact.
Thanks
Ankur
