Breakdown mappings enable you to define relationships between the indicator source
table and the breakdown source table. This behavior enables 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.
