Hi Every One ,
i have a SSRS Report which has multiple Report paramters and this Report is a Subreport inculded within the Main Report.

This Sub report is taking hell amount of time(around 40 min) to fetch the result. while the sql Query is taking only 10 seconds.

i tried to use OPTION(Optimize For Unknown) Considering parameter sniffing.but no luck i already invested half a day in trying various options.

What I have tried:

has anyone any sugesstions please.

Solution 1

Check if you are passing the same parameter to the stored procedure as in the sub reports.
some time issues might come while passing nulls,empty and datetime values.

Also look if your are doing any opertions in the reports (sub reports) such as grouping , filters or converions

check if you are using the latest subreport (update sub report).

Is this report working while you preview.
