How can I debugg a role on 4.0B?

[Torsten Schnorpfeil]

Hi Flowies,
 
here's the thing: I've created a dynamic role on 4.0B. When I'm testing =
the function module everything is working fine. But within the role the =
function module doesn't return any values to the workflow. The container =
defintion of the role should be fine.
Is there a way to debugg this thing? Unfortunatly the features from 4.6 =
are not on this R/3 release.
 
Any help highly appreciated!
 
Regards,
Torsten
