This method should be called prior to calling the Render method for a report.
Depending on the execution properties of the report, the returned ExecutionInfo may either be a snapshot ready to be rendered or a report that needs to be processed. If a HistoryID is specified, the report has already been processed and it will be able to be rendered immediately.
The returned ExecutionInfo object will contain a new ExecutionID.
By default, report edit sessions are set to 7200 seconds (2 hours) from last use, making it possible for users to keep a large amount of data in the cache for a prolonged period of time. In some usage patterns, this could lead to a larger load on the RSTempDB database and the report server. In these cases you should consider using LoadReport.
