"Single Transaction" property of data source

I've got a monstrous beast of a report that has about 15 datasets. I've
figured the only way i can imporve performance is if I could somehow put some
of the parameterized data it pulls into a table that the other data queries
could reuse. (Is it possible to use a temp table? I would think not if the
queries are all in different sprocs). The only way I can see this happening
(from searching the newsgroups) is by making sure that everything is done as
a single transaction in the data source, but I can't find that property
anywhere?! Where do I set that property on the datasource, to do "single
transaction" pulls?
thanks a million if you can help me.
isamuMicrosoft MVPs are you there? I'd really really appreciate it if I could get
some help here. Thanks!

checkbox "Use Single Transaction". This indicates the data sets that use
this data source should be executed in a single transaction. So, if all your
datasets use the same data source and you apply a single transaction - you
are almost there.
Although we don't guarantee a certain execution order across datasets of the
same data source (and it may change in future), you can assume at least for
RS2000 that the order of execution is the order of the <DataSet> elements as
defined in the RDL XML. Just try it.
Hope this helps,
Robert

"Global" Report Parameters

Hi,
I have a report with 3 different datasets. How can I add a parameter to
this report which works or is valid for all the 3 datasets?
ThanksYou should be able to simply add a parameter to the report. These variables
can be accessed by any dataset.
HTH,
Brian

>|||I think what you are missing is the concept that there are query parameters
and report parameters. RS creates a report parameter for each query
parameter for you and maps them. You can change this mapping by clicking on
the ... in the dataset, parameter tab. You can map to an expression or to a
report parameter. In the layout tab menu report-> report parameters you can
remove, rename, add parameters.
