FAB Data Model

The FAB Data Model is used to define the data structure and provide the methods required to set the data or to retrieve data from the SAP server. The controls can be bound to a model to allow the connection and synchronisation with data sources. To view the data structure declaration, you can right click on the Data Model and select Generate Type Declaration that shows the declaration in ABAP format, or select View as JSON.
