The only thing I am not sure if is the fact that you want to do this with an ALV. The ALV is acutally another component. I'm not sure you can trap the context menu in the WDDOONCONTEXTMENU of the parent component. There are many other ways to extend the ALV using the Toolbar however.

Hey.

Why did not you add new function in standard toolbar of ALV ?

You can create your own context menus for user interfaces elements in Web Dynpro for ABAP.

First,you need to add code in order to create your own context menus in WDDOONCONTEXTMENU hook method .

Second,you need to create acction for your own context menus item. At one time,you need to add code in action method. When context menus item will be click,this method will be called and respond

your handle.

Below are test code of sample. Hope that these are helpful.
