Reports and Documentum

Hi,

I am using Crystal Reports to produce reports on various aspects of documentum and its users.

At the moment I can access Crystal reports through documentum, but each time i do the report updates itself automatically.

I would like the report to run at a particluar time e.g. 12 midnight each day, and save in a cabinet with that days date as the file name.

Is this possible? Do I have to create a batch in order to do this? If not how would I go about it?

Any help would be great!
