https://communities.sas.com/t5/SAS-Programming/Accessing-Reverse-Impact-Analysis-by-Data-Step/m-p/6972#M4 Hi In SAS DI Studio 3.4 you can back track a target column all the way back to the source table/column through multiple jobs and intermediate tables. Is it possible to access this metadata information by writing a data step? (I need a list over all columns for a given set of tables, where all the mapping information back to the source is present) Mon, 18 Feb 2008 13:35:00 GMT deleted_user 2008-02-18T13:35:00Z https://communities.sas.com/t5/SAS-Programming/Accessing-Reverse-Impact-Analysis-by-Data-Step/m-p/6972#M4 Hi In SAS DI Studio 3.4 you can back track a target column all the way back to the source table/column through multiple jobs and intermediate tables.
