CRM report scheduling can be done in 2 ways, namely,
1. Standard Subscription
2. Data-Driven Subscription
Scheduling with Standard Subscription:
As a prerequisite for Scheduling with Standard Subscription, you must capture Snapshot first. A Snapshot contains layout information of a report and results that were captured at a specific point of time. Report snapshots are processed for schedule and then saved to a report server. When you select a report snapshot for viewing, the report will be retrieved from the report server database. Report snapshot is a pre-executed report.
Whenever a user wants to schedule a report to static recipients (e-mailing to certain specific users statically) then standard subscription will be used.
