Hi Ganapthy,
As Durgamadhab said, there is a restriction to limit number of rows in Universe as well as Report.
Please check below two settings:
In Universe,
Open Universe Parameters > Go to Controls tab > Check whether Limit Size of Result set Option is checked or not.
In Report,
Edit the Report > Go to Query Properties > Check Max Rows Retrieved Option is enabled or not.
Please uncheck above two options, if you find it is checked.
Hope this helps..
Cheers,
Bala
