Achieving Subquery filter with Max value in Webi

Hi All,

I need help with achieving the following SQL output through Webi, here a little background on the tables followed by the SQL that needs to be achieved on the report,

From database we have connection_enum table, we are able to bring this table into IDT , here is the SQL in question:

select    root

from      connection_enum e1

where   e1.id =1234

             and Column1 = (select max(Column1) from connection_enum  e2

                                   where e2.num = e1.num)

Please feel free to share your thoughts or insight on this, any help on this will be appreciated.

Thanks
