Runtime Polymorphism / Dynamically load components in Web Dynpro for ABAP

By Saurav Sardar, Tata Consultancy Services

Scenario: Suppose we have 2 different components including corresponding views.  We want to open those different components from another view dynamically.


Create one interface which will be implemented by two different components.

1.     Go to transaction SE80 .

2.     Select “WebDynpro Comp./Intf” from the list (as shown below)

3.     Give the name “ZINF_TEST” as interface name. And choose the radio button Web Dynpro component inter face.  


4.     Now right click on the interface component and create one interface view. Interface view is nothing but one window. Because we can’t make on view as interface enable.  

5.     Now give the name of the view COMMON_WINDOW.  

6.     Now activate all components.

Now create first component:

1.     Go to SE80 again and Select “WebDynpro Comp./Intf” from the list.

2.     Give the component name as SUB_COMP1.


3.     Go to the main view and creating one Group UI element for component1. Put the text (Caption) as Main view for component ZSUB_COMP1.

4.     Delete the default window.


5.     Now double click on the component and go to implemented interface tab.

6.     Put the interface name and click enter button.

7.     Now clicks the Re-implement button to implement the supper Web Dynpro interface class.

8.     One success message will come after implementation.

9.     Now save this component. One inherited window will appear in this component; this is interface view of the ZINF_TEST component.

10.  Now embed the main view in the COMMON_WINDOW.

11.  Save and activate whole component.
