BackgroundWeb Dynpro Model

 

Web Dynpro technology is based on the Model View Controller paradigm, to ensure a clear division between the definition of the user interface and the implementation of the application logic. Within this concept, the model retrieves the application data from the back-end system. If you want to define multiple models, the model must be bound to the relevant Web Dynpro component that the model is to use.

The data for a Web Dynpro application can originate from different sources. You can:

  • Call and use SAP data from a SAP back-end system using BAPIs

  • Define new data

  • Call and use Web services

  • Combine the three above procedures

  • Import an external model using the appropriate tools
