Summary :
The SAP Note identifies issues with unrecognized service names such as 'sapmsOSS' during service lookups, affecting connections to various SAP components. Errors from 'NiPGetServByName' indicate missing directory services entries, preventing successful resolutions of service names to port numbers, impacting connectivity and gateway processes. To resolve this, update local or network-wide services directories (e.g., '/etc/services' on Unix) or use directory services like NIS to ensure the correct mapping of service names to port numbers. Verification can be achieved through tools like 'niping' to ensure service name resolution functionality is restored.
