Help needed! When I run semantic check:
- Rules for a service-oriented EPC
- Process parallel flows, inclusive decision paths and exclusive decision paths are well-formed
on an EPC with a Cycled Event, I get the error:
- Incorrect structure. Closed structures cannot implicitly nest open merge structures
I do not get any indications of errors by use of information marks in the model.
Can someone enlighten me with what I'm doing wrong in the below EPC with a Cycled event?
How can I fix this model so I don't get sematic check error?

Hello Ian,
I think, there are 2 things to be changed in the EPC:
1. eliminate the event "Object B approved". It is followed directly by "Object A&B completed", which makes an event follow an event.
2. I understand, Cycled event 1 is used as 2 occurrence copies of the same event. The structure becomes clearer, if you draw the connection from the bottom occurrence directly to the merging XOR-rule. I think, then you should be fine.
If I draw a connect between Cycle event 1 occurrence and the XOR rule, the No cycle may exist in the model error is produced in the semantic check. This is why I'm using a Cycled Event (occurrence copy of an event) as per this thread http://www.ariscommunity.com/users/twgathings/2010-09-27-no-cycle-may-exist-model.
