I understand that a history can be created in Reporting Services. Is
it true that when you click on the "New Snapshot" button, you get a
report using the default parameter? If so, then the "history" feature
is pretty much useless as you can only generate one version of the
report. What we want is to be able to take snapshots of a report at a
give point in time with the desired parameters.
Thanks for any input here.Yes, snapshots in the history are taken with default values of parameters.
If you need to store snapshot with different parameter values, you need to
set different defaults and then take snapshot. Also, when you render that
snapshot, you can change values of parameters that are not used in query.

From a user point of view, I changed the parameter and I want to take
a snapshot of what I did. That would be a fair enough request,
wouldn't it? The administrator can't give a user Content Manager right
for him to change the default. May be this can be included in
enhencement for the next release?

Eugene|||We consider this as a request, however, it is not as straightforward as it
seems.
1. Snapshots were not intended to be a replacement for a good Data
Warehouse. Every missing feature about snapshots (and even snapshots
themselves) can be "worked around" by setting a data warehouse that can
reconstruct result of a query for any given time.
2. History is bound to a report, not to a user. Items in history don't carry
any individual security. Anyone who have access to a report would be able to
render from history. Therefore, personal preferences of a anyone, creating
snapshot would affect all users.
3. When allowing defaults only we identify snapshots by creation time. If we
accept parameters, we would have to introduce other means to identify and
manage snapshots. It would be possible and reasonable to take multiple
snapshots at the same time.
4. In many cases, users can create a linked report, provide different
default values for parameters and take snapshot of that linked report.
