ou You can use the RFC API (Remote Function Call) to set up an RFC connection from an external system to an SAP system that can communicate with the SAP system as a client or server.
Required Files
For 64-Bit Environments the following DLLs are required:
- sapnwrfc.dll
- icuucXX.dll
- icudtXX.dll
- icuinXX.dll
(XX can vary depending on the version of the NW Rfc Libraries)
However, you must copy the Netwaever DLL files on the Webserver and the host where the Synchronization Service is running to the subfolder system in the Windows folder. (Typically, this folder location is C:\Windows\system32)
