Thanks Deepika,
When you create context node you will get popup with class name, there you can change the class name.
-> we do not get a POPUP for giving a class name , it comes along with the POPUP for giving the package and not changeable.
This BADI BSP_WD_APPL_WB worked for me thanks![]()
How ever do you have an idea how this BADI is implemented for a specific Commponent.
