List Of Values issue when created a query filter in the report instead of Bex

Hi All,

I am using CR4E. I am trying to create a query filter in the crystal report instead of using the BEx variable (just because it allows me to have "Search"option in view mode. But the problem is when I create a parameter in the report and refresh, I get the LOV's for the first time. But when I close the report and reopen and refresh the report,LOV's disappear and I get the blank screen. I would like to know if I am missing something or CR4E doesn't support the report paratmeters with BW datasource. Please let me know.

1. First Refresh after creating the parameter:

Second refresh after I close the report and reopen and refresh:

Thank you,

Madhavi.
