how to see source value of property set in Tracer
hello, how to see source value of property set statement in a Data Transform in Tracer?
E.g. I see below lines in Tracer. The set .LastName and set .FirstName statements are from a DT.
I would like to see what's value set to .FirstName, .LastName at that time.
But I can not see this by clicking diff column of the line. Two possible result shown. No source value see.
Thanks.
