If a snapshot exists when the credentials are set and AllowQueryExecution is false, the snapshot will be cleared, and any parameters will be reset to their default values.
If there are multiple data sources that prompt for the same report, you need to specify all of the credentials at the same time. If one set of credentials must be changed, you must supply all of the credentials again.
Credentials are only persisted for the lifetime of the execution, after which they must be specified again.
