This section contains information on connection to SAP systems and is therefore a prerequisite for all subsequent sections.

RFC Library (API) #

The RFC API (Remote Function Call) enables an RFC connection between an SAP system and an external system that can communicate with SAP as a client or server.

The RFC API has two versions:

  • classic RFC-API (classic RFC library).
  • Netweaver-RFC-API (Netweaver RFC library).

For more information on the RFC libraries, see SAP Help - RFC API: Classical & NetWeaver.

Information on connecting to an SAP system is provided in the following sections:
