SAP Rel. 4.6B and background tasks in workflows

[Eivind Bustnes]

Hi,
 
I have a 4.6B system, where I have made some extentions to a objecttype
(FIPP, BUS2012 etc.). I have made my own methods which I link to a task in
a workflow.
 
The problem is that I want to run the task as a background task, and when I
do this it seems that the system doesen't read the method. If i run the
task in the foreground instead the method is read and the task is working.
When i do this in a 4.6C system everything is OK. To me this seems like a
bug in the system, but I can't find any OSS notes describing the problem.
 
Have anyone experienced the same problems or have someone a suggestion to
what I should do?
 
Best Regards Eivind Bustnes
