RFC Context

Every remote call of a function module that is made using the RFC interface defines a separate context in the target system. The function group of the function module is loaded into an internal session of the context, and is retained. What this means is that, if repeated calls of function modules belonging to the same destination and the same function group are made, the global data of this function group can be accessed collectively. When functions are called in external systems, this behavior is simulated by the API of the RFC library. A connection and its context is retained until it is explicitly closed, or until the calling program is finished. To close a connection explicitly, the function module RFC_CONNECTION_CLOSE can be used, or the API functions RfcAbort and RfcClose.
