I have a question about how to model the following process in a BPMN environment
The process is about handling orders. A part of the process is about handling order lines. Since 1 order often contains multiple order lines and handling order lines is done in parallel, I used a parallel sub-process for handling order lines.
Parallel to this sub-process there is another flow. An activity in in this flow can sometimes only be done once an activity within the sub-process for handling orders is carried for every order line. I do not know how to model this. Is it allowed to just place an arrow between the activity within the sub-process through the borders of the sub-process towards an activity outside the sub-process? I also prefer to use the model with the folded-down sub-process, so even when the issue in the previous sentence is allowed, I do not know how to model it with the sub-process folded down.
I hope there is another possibility to indicate this dependency. Does someone know this?
