Internal error while transforming bpmn to bpel

Question

Hi,
i designed a simple bpmn model and i’ve got an error while transforming the model into a bpel process.
Steps i’ve done:
1.     SOA > Transform business process into bpel process
2.     the following semantic check was ok and there were no errors listed
3.     I selected the check box “create log file”
4.     Then an error occurs: “Unable to perform transformation. Internal error: There are semantic errors in this model. The errors have been displayed on the model”
5.     After clicking OK, the log file appears: -- WARNINGS --: W#17 : Warning: in the current model, some functions are not connected to services.”
6.     in the bpmn model there are two objects marked with a red line: an automated activity and a XOR gateway (data-based).
I don’t know what’s wrong with these objects. I checked the properties of the automated activity, but “Abstract BPEL activity” is selected and so I don’t understand what the problem is.
Are there dependencies, I don’t see? The assignments of both objects are correct. Are there other requirements i have to consider?
Previous to the automated activity there’s another XOR gateway (data-based) with three branches (one of them is the obviously incorrect activity) and all three branches meet in the red marked XOR gateway.
Any idea?

Hi Julika,
The error message might not be related to the activities itself. I assume your model is not well structured. Consider that the following points aren't disregarded:
* Never "jump" out of a particular branch into a different part of the model or into another branch
* All functions/events have only one incoming/outgoing connection
* Process parallel flows should be specified by splitting and joining AND/XOR rules, or they should contain either one splitting AND/XOR rule only for which there is no other connection between their paths, or one joining AND/XOR rule only that is met by all connections.
Let me know if it did not help to fix your problem.
Best regards,
