I understand the ProMapp is to help make Process more simplify but not all business processes are in a linear fashion. With that being said, has anyone came up with a good solutions to portray business processes that would go back to a previous step or steps further back in the process based on an decision or if the process goes to another process that then needs to come back into the process that started it at a particular point. I understand yes you can make notes in the particular activity in the process to be if this happens go back and refer to activity 2.0, but if someone is looking at the process at a high level (map) they would not know this.
We add activity boxes to show on the map, which direct the user back to a previous activity . This is not perfect but it is a reasonable workaround and stands out more than the notes field. See attached example.
