Rollupprocessing: Does anybody knows what is this? (CRN)

[abelius]

(Excuse my english, please)
In Framework manager, in the properties of a Data Source, there is a parameter called "Rollupprocesing". Does anybody knows something about that?

I've been seeking the KB and the online help and so on, but there's nothing!

Thanks you all.

I belive Rollup Processing is for determining where the Sums, counts and other such aggregations are performed.
If set to database, you will need huge Temp Space on the database. Local will reguire large Ram and Temp on your ReportNet Server. I am not too sure about Extended.

Create a simple report that does some Sums or Counts and text each one for performance. because this is primarily set to improve performance based upon your needs.

Hope this helps.
