Below is the architecture of ABAP RESTful Application Programming Model to develop Odata services. dataCategory: #TEXT to signify this is text view. We could implement a code block like so in the DEFINE method of the MPC_EXT class and add the desired term directly as an attribute of the produced oData property: The backend code would look something like: DATA(lo_entity_type) = model->get_entity_type( 'YourEntityType' ). The answer is simple: we provide the dictionary information to SAP Gateway Foundation. The method name to achieve the same is – DEFINE. But The static variable will only persist the incremented value only if there the soft state is activated else (makes sense) else it will always show the value ‘1’.
