Sorry i was on holidays with less internet access.
The Solution is as below:-
1) Created a Subtype BUS2007 with new event 'CHANGED' for Tcode IW32.
2) Configured it in SWEC with the new ZBUS2007 CHANGED event and change button selected.
3) Configured the ZBUS2007 event CHANGED in SWE2 with a receiver FM without any RFC rest is as mentioned in my thread.
The problem is you cannot debug the receiver FM, So what i did is i put the same code in another FM and put it in Check FM. That too you cannot debug with internal or external breakpoint. So i used infinite look debugging concept and debugged it using SM50. It then triggered my FM.
