Hi,

I created a report with data from more than one table.
Now am facing a problem.
i.e The report with required data is generated but more than once(same data is displayed in all pages).
please let me know where I have gone wrong.

You have joined two tables that have a 1-many or many-many relationship. That is causing what appears to be duplication. What are you getting from the many-side table? Normally you would use a main report for the 1-side data and a subreport for the many-side data.
