Dear all, I am posting in the hope that somebody could give me some direction regarding a project that I am starting at the moment. I am looking for a way to improve the traceability of the variables that I create an use in various SAS datasets. My (very general) question is about finding a way of automating a program which would return information such as: a) The definition of the variable, for example, if I have done: data base; set base; a=b+c; run; I am looking for a way to return information about the variable 'a' being derived from b and c. And the formula that was used to do this. b) the source of a variable, i.e. whether it was defined using other variables or imported from another database. I realise this is a pretty general question, but any tips or suggestions that anyone has would be greatly appreciated. Thanks Ben ... View more
