sa.max_relations_in_service

ServiceNow property description:

The number of CI relations, exceeding which application service is not displayed automatically in the map view. Very large application services may cause performance issues. Instead of maps, users can view CI lists for large application services. The default value is 5000. Setting a negative value results in not limiting the number of added CI relations. Setting an invalid value, like a string, is equivalent to the default value, 5000.
