What is a Snapshot in Impromptu ?

A Snapshot retrieves all the information for a report and stores it in a permanent cache on the PC. The data is stored along with the report format in the *.imr file.

A Snapshot can be used like a database. You don’t need access to the database to use a snapshot.
Snapshots do not allow you to apply less restrictive filters and add one or more columns.
We can schedule Snapshots using Cognos Scheduler

Use a snapshot when you need
- All the data for the report in one file
- To email report as a single file attachment
- Open a report without access to the catalog
