What does the RFC adapter do

I cannot understand what the RFC adapter is meant to do. Does it just allow RFCs in one system to be used by RFCs in another system using this scenario:

RFC (System1) <-> RFC adapter <-> XI<-> RFC Adapter <-> RFC (systme2)

    Hi Patrick,

    Yes you are correct.

    RFC Adapter enables you to use the functions of the Integration Engine in existing SAP Systems. It is used by SAP Systems to connect to the Integration Engine by using the RFC Interface.

    It uses SAP Jco to manage the connections and the metadata to map RFC data to RFC-XML and vice versa.

    For Ex:

    Sender (SAP R/3)-->Convert RFC data to RFC-XML

    >XI Routing & mapping -
    > Convert RFC-XML to RFC Data---> Receiver (SAP R/3)

      Hi Patrick,

      RFC adapter is used to call RFC functions in R/3 from XI.

      You always specify a RFC destination which points to a Business system (R/3) and XI runtime makes a call to this destination only.

      If you have R/3 in both side ,one might argu why use XI as both understand RFC.The call that you take is the architecture that you want to use.Using XI would decouple source R/3 from target R/3.In the event of a change in either the source or the target the other side remains unaffected (this is just one of the advantage).It also has other benifits like centrally integration knowledge(interface ,mapping) is stored.
