# Certification Audit Logics

# Certification Audit Logics {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026

Audit Results are created for each audit executed on records that matched the selection (see matching conditions in Initial Certification Audit Run).

The result's state can be certified or failed. A Follow-On Task is created for each 'failed' Audit Result record.

## Initial Certification Audit Run {#certification-audit-logics__section_kh4_ycf_b2c}

Validating specific CMDB tables for anomalies.  
The Service Operation CMDB Compliance Audit starts to run on the CI Relationship table (cmdb_rel_ci), but only on specific records with matching conditions as follows:

* Parent AND child CI classes are supported classes, including extended tables as follows:  
  slot (cmdb_ci_container_slot), subslot (cmdb_ci_container_subslot), card (cmdb_ci_interface_card), interface (cmdb_ci_ni_interface), telco equipment (cmdb_ci_ni_telco_equipment), IP switch (cmdb_ci_ip_switch), and IP router (cmdb_ci_ip_router).  
  Note:  
  These properties can be configured via sn_tsom_core.audit.\* system properties.
* Parent OR child is created or updated by Discovery (discovery_source = SG-Altiplano, ServiceNow). Audit uses its own filter mechanism that applies on equipment Cis. Default filter is "discovery_source CONTAINS TSOM"
* Parent AND child life-cycle Stage is Operational.
* The CI Relationship Type is Contains::Contained By.  
  Note:  
  This property can be configured in the sn_tsom_core.audit.relationship_types system property.

## Subsequent Certification Audit Runs {#certification-audit-logics__section_i5h_j2f_b2c}

Follows the same logic as the Initial Certification Audit Run, but with the following additional matching selection criteria:

The audit runs when the Updated field timestamp is later than the Last run date in the Telecom Discrepancy Audit. The timestamp can be from the CI Relationship table, Parent CI, or child CIs. This indicates a change since the last audit.
