i am attempting to average or sum a number of timespan objects using the "results" tab inside a "data from other datasource" definition, and instead of an error message, i get a blank screen.

i can average them correctly if i change them to a .TotalSeconds double... but i want to keep it in the correct timespan format.

is that possible?

thanks

Hello, Erik

We have fixed this error, the update will be available in prerelease build on May, 24.

Thank you.

This does not appear to have been fixed in the latest pre-release.
I have a calculated column as a timespan set to DateDiff(new DateTime(2011,3,1),new DateTime(2011,2,2))
I then create a Data from other Data Source against that table. In the Results tab I add the timespan column and select Avg as the Aggregate function. This automatically creates a column in the new datasource, but its type is incorrectly set to decimal. When I change the type to timespan the report fails when run.

Hello, Jay.

Calculated columns cannot be used in Data from other Data Source. Even if they are shown, then they work incorrectly. So, please do not use them in the Data from other Data Source.

Thank you.

Is it just TimeSpan calculated columns that dont work in "Data from other Data Sources" ... or ANY calculated column? We have been calculating the average of a decimal Calculated column fine in the "Data from other Data Sources".

thx,
Jay

Hello,

If you add calculated columns (not only the TimeSpan type) to the data source, and then, on its basis, create "Data from other Data Sources", then, in the new data source, calculated columns obtained from the main data source may work incorrectly. In the .Net version of the product they are invisible from the dialog box when adding.

Thank you.
