While deploying an inbound module to test environment, if you get an error message stating
that the "service 'sapxxnn' unknown" (where xx is two letters, and
nn is two numbers), you can resolve this by adding a missing entry
into the services file.
This error is caused when
the SAP gateway protocol 'sapxxnn' is
not existing in the services file. In UNIX,
it is located in
etc/services and in Windows, it is located in
\WINDOWS\system32\drivers\etc\services.
To verify and resolve this error:
- Open the services file in
a text editor (notepad or wordpad) and
search for a valid 'sapxxnn' entry.
- If it is not in the services
file, add the line 'sapxxnn' (minus
the quotes) at the bottom of the file. There must be a carriage return
at the end of this line if it is the last line in the file.
- You
also need to add port/protocol in addition to the 'sapxxnn'
entry. For example, sapgw00 3600/tcp
