In previous versions of SharePoint, there was a rule that you couldn't have two instances of a workflow running at the same time on a given item.
On SharePoint Online (2013 version), it seems that the rule does not apply the same way.
I have a long-running list workflow with two start options, when an item is created and when an item is changed. Here is what happens:
- When an item is created, a first instance of the workflow starts
- when I change this item, a second instance of the workflow starts (the first one is still running)
- when I change the item again, no new instance of the workflow is created (the above two are still running)
Is it the expected behavior? If so, could someone explain the logic, and point me to the Microsoft documentation where this is explained?
