I'm trying to create a multiple workflow for a team, where one user will select which teams are going to participate in it. (Blocks) Based on selection each workflow tasks in the block will start to execute.
Once all the activities of the selected blocks is completed the next activity should execute.
Is there any method of achieving this? I've also explained with the help of an image.
I'm not sure I understand correctly your needs, but I kind of recognize the Change Task with sequence in a Change Notice.
When Windchill is setup to use sequence in implementation plan of a change notice, you can decide whether the next change task starts when the previous is completed.
