Hello, I am trying to clean up some code for processing updates from a transaction dataset to a master dataset. I ran across this SAS paper and subsequent SAS documentation that explains how to use the MODIFY statement to achieve this. http://www2.sas.com/proceedings/sugi31/264-31.pdf All of this works as instructed, but I need it to work a little bit differently and I have not been able to figure out how to do it. In this paper, it talks about replacing the record in the master dataset if it also exists in the transaction dataset. The issue I have is that I only want it to replace a record if the data for one of the records variables has changed. In this case above, the entire record is rewritten because they match, regardless if any of the data has changed. The reason I am trying to do this is because I want to be able to track and report on records that have had data change each day. Is there a way to do this using the methods in this paper or similar? Thanks!
