I have a CR 2008 that was updated from CR 8 it worked then doesn't now.  This is on an Oracle 10.2.0.5 db.  There are 12 tables in this report.  I have tried recreating the Report from scratch but nothing pulls. I have tried putting in one table at a time and pulling the fields that I need. I get data back. So I know that it is connectected to the db but when all tables are put together no data. I even took all the formulas out and only used a date parameter query and no data came back.  Any suggestions would be greatly appreciated.

You also might need to look at changing some or all of your joins to outer joins.  If you're joining to at table that may or may not have data based on the join, you need to make this an outer join.
