Finally I made the testing. I had to implement certain changes to my workflow (eg. data assignments, status checks, had to be moved outside the task) but finally it works.
Thank you all for tipps and hints.
Sorry the late response. I implemented parallel task, but I need to test it with multiple users.
@David Rutt: the people getting the task assigned are changing, But once they are assigned to that specific task, they won't change anymore.
@Martin Zebedies: I thought I have to steer this with the cancel condition. Anyway I will give parallel tasks a try, thank you for the tip.
@David Rutt: in the first task (the "assignment task") a user selection list is presented. The selected users get the seceond task assigned.
I want to implement a specific release workflow. First step is, that sombody assings the release tasks to mulitple users. That can 1, 2 or 3, depending on the docuement.
All assigned users get a task. But currently the task is already finished, when only ONE of the users is answering (approved, rejected).
Is there a way, to collect all answers before the final task decsion is taken?
I tried to overcome this artihmetic function, but I failes to determine the number of assigned users.
