Optional Parameters Becoming Mandatory in InfoView

Hi,

I designed Crystal Reports on top of Bexquery.

Bex Query doesn't have any filters.i created optional static parameters in Crystal Reports.

When i Executed Crystal report all my prompts are acting as option,But when i run the same Crystal Report from INFOVIEW all prompts are becoming mandatory.

EX:- in my Crystal reports i have 5 prompts.In INFOVIEW if u give only one prompt value and execute the report,its not executing. Until we select values for all the prompts Report is not executing.

Experts I Need quick help on this.

Thanks,

Chandra
