BEX :Selection screen missing when executing a query

Hi all,

When I am executing a query through BEX Analyzer,I am not getting the Selection Screen Popup.Instead ,the report is directly being generated.So,this is giving rise to various problems.But when the user is executing through portal,he is getting the selection screen.

I am not getting this Selection screen popup in all the DEv,Quality,PreProd and Production systems.And hence ,i am not able to give the selections for a report

Can anyone please provide a solution for this?

Awaiting your response.

Thanks,

Amar
