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.
Use cases address workflows with different Branch and Merge node options depending on if you have specified conditions in your workflow.
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.
