Invalid workflows

To prevent the creation of an invalid workflow, the Central Designer application enforces the following rules:

• The sequence of workflow steps cannot be circular. The last step cannot point back to the first step.
• A study object that is associated with a global condition can have only one prerequisite step, and you cannot associate a global condition with a study object that has more than one prerequisite step.
• A study object can have only one outgoing arrow. Branching to two different study objects requires a workflow rule.
• The workflow action for each branch of a workflow rule outcome must be unique. For example, if a step follows a workflow rule when the expression evaluates to True, the other branch of the workflow cannot also be based on the expression evaluating to True.
