Adapter for SAP incorporates a full-fledged RFC Client and Server. These provide real-time bi-directional (outbound and inbound) communication to and from the SAP system. From an SAP application point of view, calling Adapter for SAP is no different from calling any other RFC server. The SAP proprietary RFC format is converted to XML so that no SAP software is needed on the other end of the communication line.

Adapter for SAP transparently supports both synchronous (RFC) and asynchronous (tRFC) calls from SAP systems. Thus, BAPIs and ALE scenarios are supported. Adapter for SAP also supports qRFC for IDoc processing and inbound bgRFC calls from SAP.

As a special service, SAP IDocs can be converted to a structured object with direct access to each single field. This allows you to modify an IDoc's contents on the fly. For example, if you want to customize incoming IDocs based on local data format, you can do so. You can also access existing BAPIs in SAP systems from a browser or client application, or you can send XML documents to the SAP system. Developing applications with Adapter for SAP requires no knowledge of SAP data structures, significantly reducing deployment time and cost.
