Hi,
Is there a way in OBIEE to pull all the report where a particular column is being used instead manually opening each and every report and looking for that column.

Have a look at SampleApp, and the utilities that come with it. One of them scans through your Presentation Catalog and inserts details of every single analysis (including columns used) into a DB table, which is then exposed through the RPD for querying. Works for 11g and 12c.

There's Catalog Manager too, which includes a Report function that will also give you the data you want.
