BO WEBI Report - Date filter / Prompt issue

Hi,

I have created WEBI Report based on HANA view via IDT. Date Field name are product start date and expire date.

Now user is want filter those product which will expire today ( 2015/06/12) means expire date column should shows only todays date..but WEBI Report pulling all the expire date including todays date ,2015/12/31 etc....but Hana view is working fine...Please suggest.

user input :Enter Expire date .

HANA view and BO  Dateformat - 2015/12/31

HANA -Date is variable - range

HANA view filter is working fine and data are showing only one date  data. No other date is coming in HANA view but so many dates are coming in WEBI

Regards,

Kamruz
