Thanks Aritra,

at the time of modi repo it displays fine and as and when I click on any button of the preview control such as page navigation or zoom or print I will get error that 'Variable ... Not found' If I see this report in vfp window I dont found any error with same query and same variables.

Now I have tried out with data environment so I have cleared this error but I found that If I click on preview control such as page navigation or zoom or print I will get zero value report and my table in data environment is having 1 row.

I will be thankful , If you give me some solution

Thanks
