Other components include enterprise portal, exchange infrastructure, master data management and mobile infrastructure. Its main component is the SAP Web Application Server (WebAS), which provides the runtime environment for SAP applications like ERP, CRM, SCM, PLM, SRM, BI. SAP NetWeaver: one of the main technologies and application platforms used by SAP solutions. Applications are integrated through synchronous and asynchronous communication, rather than by use of a central database. This involves business-driven message exchange using consistent data across loosely linked SAP applications. ALE facilitates distributed, yet integrated, installation of SAP systems. Multiple message types with related content can, however, be assigned to a single IDoc type.ĪLE (Application Link Enabling): technology for setting up and operating distributed applications. Different messages types (such as delivery notes or purchase orders) generally correspond to different special formats, known as IDoc types. IDoc (Intermediate Document): standard SAP format for electronic data interchange between SAP systems. Runs to completion with or without user interaction. Maintains a static interface through different versions of the SAP system.

Implements a method of a SAP Business Object. It consists of the following add-on packages: SAP Java IDoc Class Library: provides structured, high-level interpretation and navigation of SAP IDocs in Java. RFC Layer: SAP component that processes RFC calls. RFC Library: libraries of C language-based functions to access the SAP system. The RFC interface enables function calls between two SAP systems or between the SAP and external system. RFC means calling BAPI or triggering IDoc processing that runs in another system as calling program. RFC (Remote Function Call): communication with the SAP system is performed over the RFC protocol. RFC Middleware uses RFC Library through (JNI) Layer. JCo wraps C libraries in Java to provide platform-native access into the SAP system. JNI (Java Native Interface): originally, SAP created libraries in C language to allow direct RFC calls to SAP, to manipulate data. Java apps are built on top of the Java API. It implements JCO.Function, which is the container for parameters and/or tables for the SAP Function Module (BAPI) in Java.

Java API: handles dynamic metadata lookup and caching.
