Nested Filter

Hi Everyone,

I am stuck with a nested filter, below is what i want to do:

and (

          ( ( b.auto_renewed_counter > 0) and (B.OPEN_EFFECTIVE_DATE between '02-aug-2015' and '25-aug-2015'))

              or

              (

                  TO_DATE(CASE

                   WHEN A.ACCT_OPN_DATE <= TO_DATE('01-AUG-2015', 'DD-MON-YYYY') THEN

                    A.ACCT_OPN_DATE

                   ELSE

                    B.OPEN_EFFECTIVE_DATE

                 END) between '02-aug-2015' and '25-aug-2015'

              ))

is there any way to implement this on BI.

Thanks in advance.

Best Regards,

Mithun
