I tried this also but not working in my condition

var rep = "UI"+""+UnitId+"_";

msg.payload=s.replace(/rep/g,' ')
4

var text = "UI" + "" + UnitId + "_";

msg.payload = text.replace(/rep/g,' ')

You would need to create the the regex pattern using the constructor property

var patt = new RegExp(rep, "g");
  msg.payload = s.replace(patt, " ");
