Report sources are predefined data sets for creating reports.
Use report sources for reports containing the same conditions, so you do not have to define the
conditions more than once. You can also use report sources to implement the same definitions
across your organization.
A report source always consists of a table and a number of conditions. When you create a new
report, you can either use a report source or select a table. Some examples of report sources are
open incidents, closed problems, and so on.
