Either use a tool like Metadata Manager or write a Java SDK program to get this information from each report. Query builder doesn’t contain this information.
From a high level with the Java SDK:
Query CMS for all webi reports.
Loop through and open each webi doc.
Loop through each data provider
Check for combined queries because you need to recursively loop through them
Loop through the result objects using getResultObject() method, loop through the condition objects using multiple methods because of the complexity of rankings and subqueries checking for the object and parent folder of the specified object in the universe
Output report information you want when a match happens to file or database.
