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 table Assignment group values. You
can use the same breakdown to create additional mappings between the Group.Active
breakdown source and other tables and fields that reference the Group table, such as the
CMDB Support group field.
