In a camunda training slide I found an example of a multiple instance marker to a pool. An activity in pool A sends out a message to pool B wich has the MI marker. This means the activity sends out the message to multiple responding processes (i.e. asking multiple suppliers for a quote).
Obviously some vendors of modelers do not interprete the bpmn standard this way and argue, that MI markers are only applicable to activities and subprocesses, but not to pools, so they don’t offer a feature to do so.
So one of them seems to be wrong: camunda training slides or the vendor who told me the other story? What does the bpmn standard tell us about MI markers to pools? I guess Falko will know for sure…
