SAP Network Connections & SNC
Required Ports
The dab SAP-Extraction Solutions establish a connection to your SAP-system via TCP/IP using the RFC protocol. Depending on the scenario, this may require the corresponding ports to be activated.
If you are using a Message Server with Load Balancing, it may be necessary to activate the Ports for the underlying application server in addition to the actual message server.
Application | Port range |
Application Server | 33xx, where xx stands for the instance number, e.g. instance number 01 then has port 3301 |
Message Server | 3600 - 3699, ask your IT or SAP Basis for the exact port |
SNC | 4800 - 4899, ask your IT or SAP Basis for the exact port |
SAProuter | 3299, unless otherwise specified |
services-Entry for Message Server
If you want to establish a connection with a message server, make sure that an entry with sapmsXXX is stored accordingly in the file under %WINDIR%\System32\drivers\etc\services, where XXX stands for the system ID of your SAP system.
SNC-Support
The dab SAP-Extraction Solutions support securing and authenticating the connection using SNC via RFC. As there are many different SNC solutions, we cannot provide you with generally applicable instructions, but make sure that the following points are ensured:
- The SAP-user must be assigned to the corresponding SNC name in transaction SU01
- The SNC-Solution must be installed and configured on the same system as the SAP-Extraction Solution
- Make sure that the Bitness of the Libraries matches: if you have installed 32-Bit RFC-Libraries, also make sure that the SNC-Libraries are 32-Bit; of course the same applies to the 64-Bit
In our experience, the following SNC solutions are compatible in any case:
