Hi,

im working on a Report which needs to be able to display an unknown
number of columns; the only one that are always present is the first
one with a timestamp.

An example of the data: [timestamp], [value 1], [value 2], [value 5].

Is that possible with Reporting Services? The only solution that i have
found is unpivot the data in another form and then use a Matrix to
pivot the data back, but that decreases performance of my Report.

Hope somebody can clear this out for me, since im consider to code the
Report myself instead of using Reporting Services.

Regards, Martin
