Filter not working for a Webi report

Hi There,

We have a BOBJ Webi report having variable selection screen when I run the report with default fiscal year Ex.2012 it's working fine. Then by click on refresh button and trying to change selection value to Ex. 2013 and I'm unable to see any values even though it has values for 2013.

When I click on the filter bar then the values are appearing. Could anyone please let me know what could be the reason for this issue and how can we avoid this.

We are in BOBJ 4.0 SP6.

Thank you,

Regards,

Shiva
