Hello! I have a question about the SAS Di Studio application itself.   Say i have two tables, A and B where i need to extract data from some, but not all columns in the tables. I use the extract transformation to only get the columns I need and maybe do some other manipulating like aggregating the data. After that I want to join these two tables (A and B) to one (table C), however if I now do a left join for example then Di Studios starts to propagate the columns I previously had removed in the earlier extract transformation so they are added back in. I've tried digging in the options and under Job Editor I turned off following settings: "Automatically map columns", "Automatically propagate columns" and "Automatically create join conditions in Join" but to no avail. Is this a intended behaviour or a feature I can turn off?   Thanks in advance.   Tommi ... View more
