In a workflow where a Branch node supports more than one branch, a branch with a failing node produces a race condition where one path fails and one succeeds. This scenario is addressed in several of the use cases that follow.
After you execute a workflow, select the workflow item in the History list to view the Execution page where each step in the workflow is listed along with a status. Hover over the Unsuccessful status for an explanation.
Use cases address workflows with different Branch and Merge node options depending on if you have specified conditions in your workflow.
