If any errors occur in our Web Dynpro components, we can use the ABAP Debugger to execute our WD component, by line or by section.
To work with the debugger, we can create Breakpoints at the point where the program should pause
Setting a Breakpoint
We run the application and, in the moment when the program flow reached the defined breakpoint, the ABAP Debugger is open
As we can see in the Process Information, the main component of the ABAP Debugger, we debug an HTTP application. The “Exclusive” represents the fact that the application we debug occupies a work process of the application server.
By using the Buttons from the Control Area, we can control the program flow. For Example,We can choose to execute the program line by line-single step or to execute the program up to the next Breakpoint.Continue.
We can use the ABAP Debugger tools to have information about the variable
Tool Component of the ABAP Debugger

As we can see in, we are offered the possibility to have access to all the individual elements of the Web Dynpro component; we can see the view attributes, the view layout, the UI elements and data binding, the context structure and its attributes, etc.
The ABAP debugger – web Dynpro ABAP tool
We are able to see not only the context structure, but also to display the runtime object, by choosing from the contextual menu Display Runtime Object.
