SSRS 2008 R2 -> Multiple value selection Parameters - Select All by default -> preview report is not giving proper results, But it gives expected/specific results fine for specific parameter selection. Why So ?

Hi,

I have a report with multiple-value selection parameters (Select All by default).

When I preview report for Select All by default, I am missing some results. If i select specific parameter values, Then I can see those missed results.

How come this behavior happens ?

Can anybody suggest me, how to over come this situation.

best regards,

Venkat
