Badi : ISTEP is not reaching case 2

Hi All,

I have created a BADI implementation   in the existing Enhancement Implementation (for BEx Variable ).

Requirement: I want to run Query on latest available date in my cube which is less than or equal to 'user input date'.

This should be written in istep = 2  ?

I am able to execute/debug  the code when I am putting breakpoint at When istep = 1 i.e. inside istep = 1 code is running fine ,

But the debugger is not going to istep = 2 .

Details of variable is as follows :

Processing by: Customer Exit ,

Mandatory ,

Single Value ,

User Input Ready .

can somebody tell me what is the variable setting requirement  required for this .

Also is there any istep specific setting  in SE19.

Please help.

Regards,
