Need report of last one week skipped backups

Within the NetWorker Backup Status report category, choose any of the basic reports that are listed in the user interface. When a report has been chosen, the Configuration tab displays boxes listing the selected parameters for that report. To exclude unwanted parameters from the report, remove them from the list. Customizing and displaying report output provides information on selecting and removing parameters.

Also how we can set to get this report  to mail on weekly basis

When you say skipped I assume that is backups that did not run due to skip schedule?  As far as I remember there is no such thing since reports are usually given on what has been set to run as opposed to what is set not to run.

This is for vm backups mainly ,we need this report ,someone help me please
