You can select columns for drill-down even if you did not choose those columns for profiling. You can choose to read the current data in a data source for drill-down or read profile data staged in the profiling warehouse. After you perform a drill-down on a column value, you can export drill-down data for the selected values or patterns to a CSV file at a location you choose. Though Informatica Analyst displays the first 200 values for drill-down data, the tool exports all values to the CSV file.
