Problem message flow/sub-process/pool

Hi Bizagi support,

I know I can't create pools in a sub-process and I want to put a message flow from a task in a sub-process to a pool. First, I create a message from the global sub-process to a pool and I create an annotation in order to give some information because it's not possible to know where the message come from for example.

I hope you can help me.

Dear Julien,

Why can't I use pools, lanes and milestones in a Sub-process?Embedded Sub-processes are an Inline block, that group process elements used in a certain point in the process within a Sub-process. According to BPMN, a Sub-process should not have pools or lanes as they are dependent on the parent process and subsequently have visibility to the parent's global data.

In order to make use of pools, lanes and milestones diagram elements in a Sub-process, change your default Sub-process to a reusable Sub-process. Reusable Sub-processes allow all of these elements. Note, in BPMN reusable sub-processes are called "Call Activities".

For more information please refer to Converting to reusable sub-process



Thanks a lot.
