On the join condition on a RD I need to concatenate 4 property, I tried using the + sign to concatenate but it does not work. Is there any other way to concatenate properties for a join condition on a RD. EX - "StringA-"+.Property1+"-"+PN.Property2+"-"+.Property3+"-"+.Property4 . The example way have already been tried and it did not work. If anyone can suggest an alternate approach.
