i am not familiar with any badis/exits myself, but you can find out yourself by following the next steps:
1. Go to the TCode SE24 and enter CL_EXITHANDLER as object type.
2. In 'Display' mode, go to 'Methods' tab.
3. Double click the method 'Get Instance' to display it source code.
4. Set a breakpoint on 'CALL METHOD cl_exithandler=>get_class_name_by_interface'.
5. Then run your transaction.
6. The screen will stop at this method.
7. Check the value of parameter 'EXIT_NAME'. It will show you the BADI/EXIT for that transaction.
