Hi
I want to add a refresh a button in the output ALV for Tcode VA05. It displays a 'List of Sales Orders' screen which is a standard screen 500 of SLVC_FULLSCREEN. In the PAI of this screen I need to add functionality. So i should go for what kind of enhancement.It is not showing implicit enhancement. So to add explicit enhancement it is also not allowing me the same. As when i try to add explicit enhancement it gives the message 'Object FUGR SLVC_FULLSCREEN is part of the central basis and therefore cannot be enhanced'.
or can you suggest me some alternative method
