Detailed Explanation: In ServiceNow, thesys_idfield serves as a unique identifier for every record within the platform's database. The sys_id is a 32-character globally unique identifier (GUID) that ServiceNow automatically generates for each record, ensuring that every record is uniquely identifiable and can be referenced across the system. This sys_id is essential for integrations, queries, and relationships between records. (Reference: ServiceNow Documentation - Record Identification and sys_id Field)
