WF ProgramExists

Mike,

That is sort of what I have right now. Pre/Post BG steps on these approval tasks. 
I have a wee bit of time to play around with these WF Program Exits and 
determine if I have valid use 'without' over engineering my WF. 
It looks doable and some simple container ops seem to work... mostly anyway. 

I am hacking some of the class files in the SWF_TST package. First try was the WF Trace. 
That did not work. Won't turn on via the class file. Annoying, but got the container ops 
code and kicking around.

You use this functionality? 

I plan to spend a day or two more and see what I can get out of these class files. 

As always, thanks for the feedback.
Rick
