Get t-code of the program that raise an event?

[Rick Sample]

Can I get the t-code of the program that triggered and event on an
object and if so how? 

Example: 
BUS2032 change event triggered. How do I know what t-code triggered the
event? 

If I could get this calling t-code I could put some logic in my CFM to
process steps if called from VA02 / 01. 
Otherwise I could just ignore it and not start a WF. 

Any help is appreciated.
