Service synchronization is configured properly but the services are not synchronizing even after running the primerutility. If you happen to come across this kind of situation do the following and rerun the primerutility:
Edited the sync_primer.properties
Select only ComputerSystem and Service for SOI_Service_Synchronization_Types (Note: Later on you can add more CI types and run the primerutility again)
save the file and rerun the primerutility
Note: BinaryRelationship type is not supported for synchronization with ServiceNow.
