After upgrading a report to Crystal XI or moving to the hosted environment (which uses Crystal 11.5) it may be noticed that data is missing or the report appears to be blank. This would happen if the report was originally created in an older version of Crystal Reports, such as Crystal 8.5. This can usually be resolved by changing the Table Joins from Inner Join to Left Outer Join.
Crystal XI/11.5 defaults to an Inner Join for all table linking. This may result in missing data.
