With regards to the code, there is no 'conversion' that is required as such. You can reuse the APIs that you use in your old screen. It is only the UI that will change. Just design your screens and use the existing APIs.

thanks nithya,

That was very helpful but you see I am new to this field so could you please clear my doubt as to how to reuse the APIs.This is purely based on oops right then how?

As you would know, web dynpro works on the model-view-controller paradigm. The view is what you need to redesign, that will be your screen. For the view, whatever data you wish to display will be bound to 'contexts' with nodes and attributes.

Your APIs would be the way to actually get the data to the contexts. That can be existing classes or even function modules which you already have. You need to fetch the data using an API and "bind" it to your context node. The context data is again bound to UI elements so that it is displayed in the view.

Just search for "new to web dynpro" in the forum and you will find plenty of threads that have pointers to good beginners material.

Web Dynpro is entirely based on classes and methods only. You can use calls to function modules though. You cannot use code thats in a module pool. Which is why if your code has a clear demarcation between the UI and the actual processing, it will be similar to just plugging in a new UI. None of the underlying business logic would actually change.
