The Hierarchical Dynamic Retrieve module is written in Java and extends the Vision Connector Framework. Because the module does not have its own application-specific component, it uses the application-specific component for BAPI. Therefore, the module consists of the connector framework, the application-specific component for BAPI, the vDynRetBOH business object handler, and the SAP RFC libraries. SAP delivers the RFC libraries in Java and C. The connector is delivered and run as a Java archive (JAR) file.
Figure 29 illustrates the architecture of the Hierarchical Dynamic Retrieve module.
