Hi @TamásU,

 Dynamic CI Group membership and svc_ci_assoc population are separate processes.

A CI being returned by a CMDB Query Builder saved query and included in a Dynamic CI Group does not automatically create records in svc_ci_assoc.

       check

• Verify the Dynamic CI Group refresh job has completed successfully.
• Confirm the CIs are actually present in the Dynamic CI Group membership.
• Verify the Application Service / Service Mapping association process has run successfully.
• Check scheduled jobs and logs related to service association updates.

Since manually added CIs are appearing in svc_ci_assoc, the issue is likely that query-based membership alone does not trigger service-to-CI association creation, which is expected behavior in many Service Mapping scenarios.
