Breakdown mappings allow you to define relationships between the indicator source
table and the breakdown source table. This behavior allows you to use one breakdown for
multiple indicator source tables.
For example, you can map the sys_id from Group [sys_user_group] records in the
Group.Active breakdown source with Incident record Assignment group values. You
can use the same breakdown to create additional relationships between the Group records
in the Group.Active breakdown and other tables that reference the Group table, such as
Change or Problem Assignment group values.
