What do you understand by saving a report as snapshot?
When a report is created it become important to save it in such a manner so that it can be viewed whenever the user feel like doing so. In this context through a snapshot a report may be saved in such a manner so as to be viewed by other without the help of access. This becomes possible by saving the report as a snapshot file.
As a result, a high quality picture image of each page of report is created with Adobe Acrobat software. Other users of the report can then view the report and print any of its pages without being able to modify its contents.
