Column Profile Drilldown

Use the drill-down options in a column profile to drill down to specific rows in the data source based on a column value. You can choose to read the current data in a data source for drill-down or read profile data staged in the profile warehouse. When you drill-down to a specific row on staged profile data, the Analyst tool creates a drill-down filter for the matching column value. After you drill down, you can edit, recall, reset, and save the drill-down filter.
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.

Applying Filters to Drilldown Data

You can filter the drilldown data iteratively so that you can analyze data irregularities on the subsets of profile results.
