Technical Implementation

This section provides you with an overview of the technical implementation of an interface.

Communication is executed through the SAP interface Remote Function Call (RFC).

As of Release 3.0, data can be transmitted between SAP systems and external programs reliably and safely using the transaction Remote Function Call (tRFC).

The function module is executed once in the RFC server system. The remote system does not have to be available at the time when the RFC client program executes a tRFC. The tRFC component stores the called RFC function together with the respective data in the SAP database under a unique transaction ID (TID).

For a detailed description of the RFC interface, refer to the documentation The RFC Interface .

For more details on the TCP/IP settings, see the documentation BC – SAP Communication: Configuration .

This section gives you an overview of the program techniques involved. It is not a complete description.

If you wish to set up a connection yourself, you must refer to the documentation listed above.
