Add button on Picking EWM RF screen

Hi All,

I checked many SCN threads but couldn't get any solution for it.

Adding Push Buuton to the Standard RF Screen to have a new functionality

Add custom button on RF screen

Also EWM RF cookbook does not mention anything about this scenario.

I need to add button Picking RF screen and on clicking that custom pushbutton screen should get open.

Can anybody please let me know how to do this..

Thanks..

Jit
