Hi Charan,
To my understanding , you want to know, where you can you put code to validate the actions , if am right,
1) goto se24 open the interface IF_FPM_GUIBB_FORM. in this interface you have method process_event. Put a break point here at line number 11. And press the Approve button in the approval form. Now next method which triggers after this method is Approval method in your feeder class.
2) if you have identified approval method and feeder class, you enhance this class or make zclass of it and change configuration of the component..
If you still some doubts , please provide me the feeder , so i provide some inputs.
Thanking you
Vengaiah
