What will happen if a CI identifier is created for a child table?

When a CI (Configuration Item) identifier is created for a child table, the process of identification prioritizes the child identifier over the parent identifier. This means that if both a parent and a child CI exist, the system will first attempt to utilize the child identifier for discovery. This behavior ensures that more specific information related to the child table is considered before falling back on the broader category indicated by the parent identifier.

By using the child identifier first, the discovery process can leverage detailed attributes and context pertaining to the specific child CI, providing a more accurate representation of the overall configuration items within the ServiceNow landscape. This prioritization is essential for maintaining accurate relationships and dependencies between CIs, ensuring that any updates or insights gleaned from the discovery process reflect the actual state of the environment more precisely.

Understanding this mechanism is crucial for effective configuration management, as it allows for more granular control and reporting capabilities within ServiceNow. In scenarios where both identifiers exist, the child identifier will be the focus of identification efforts, aiding in proper CI relationships and lineage tracking.
