Exercise # 6

Exercise # 6: Objectives: Develop a web dynpro application to populate default values in the selection screen & display the label using the text objects from the OTR (Online Text Repository). Tasks required to be performed for developing the application: 1. Create Web dynpro component. 2. Create Web dynpro window. 3. Create a view with two input fields (Ex: Destination from & Destination To). 4. Select the labels of the input fields and modify the properties of the same on the screen by selecting the object from the OTR. 

Click on the Value Help of the property text, to select the existing OTR texts, whose creation is already shown in the previous exercise.



 2. Implement method WDDOINIT of the view controller. 

Press WebDynpro code wizard button



Select read context node / Attribute and use the input help to choose the context node.



Replace the method call and modify the code as below. METHOD WDDOINIT. DATA: NODE_BAPI_FLIGHT_GETLIST TYPE NODE_IMPORTING TYPE NODE_DESTINATION_FROM TYPE ELEM_DESTINATION_FROM TYPE STRU_DESTINATION_FROM TYPE IF_INPUT_VIEW=>ELEMENT_DESTINATION_FROM.
