SAP Business Components
The BEA WebLogic Adapter for SAP is designed to provide standard access to SAP business
components such as Remote Function Call (RFC) modules, BAPIs (Business Application
Programming Interfaces), and IDocs (Intermediate Documents), that are used to support
existing business processes.
These business components and methods are available to the adapter as requests of SAP
and to the event adapter when SAP invokes its remote requests and work in the following
ways:
Business Application Programming Interfaces (BAPIs) are interfaces within the business
framework that are used to link SAP components to one another or to third-party
components. BAPIs are called synchronously and return information.
Remote Function Call (RFC) Modules are SAP application interfaces that enable clients to
invoke SAP technologies and receive responses.
Note: Depending on the release or service pack installed, certain RFCs may not exist in your
particular SAP system. Therefore, the examples included in this documentation may not be
relevant to your system. If this is the case, you should use the examples as a general
reference for adapter functionality and choose an RFC that exists within your SAP
application environment.
As described in SAP Release Note 109533, SAP Function Modules (RFCs) can be delivered
with different release statuses. SAP supports only RFCs that are awarded with the Released
for Customer status. There is no claim to the release independencies of the interfaces and
the continued existence/functionality of the modules. For more information on the status
of a specific function module, consult your SAP Service Marketplace.
Intermediate Documents (IDocs) are the "logical messages" that correspond to different
business processes. They enable different application systems to be linked by a
message-based interface. The IDoc type indicates the SAP format to use to transfer the data
for a business transaction. An IDoc is a real business process in the form of an IDoc type that
can transfer several message types. An IDoc type is described by the following
components:
• Control records. A control record contains data that identifies the sender, the receiver,
and the IDoc structure. An IDoc contains one control record.
