Question { CTS, 15333 }

why do we use crystal reports rather than webintelligence
reports ?

Answer

Crystal Reports can be when more customisation of the
report is required. The complexity in creating Crystal
Reports is more than the Complexity of WEBI.
Crystal Reports formatting requires more effort and the
look and feel of export may require some modifications to
fit users requirements.
WEBI can be used for Power Users who can design their own
reports. However The flexibility on customisation of the
reports is limited.
Since WEBI is in Columns and Tabular format, there is not
much formatting effort required.
