This topic explains how to use the event editor from the Workflow module to reopen events that have already been closed. Child events whose parent events have been closed cannot be reopened unless their parent event is reopened. Closed child events whose parent events have been cancelled can only be reopened after being disassociated from their parent events. Note that reopening the parent event does not impact the status of the child events and that cancelled events cannot be reopened.
Keep in mind that if a treatment event is reopened, the risk or non-compliance that was considered "Treated" in the corresponding project will become "Being Treated". For details, see Chapter 5: Risk -> Risk Management Projects -> Risk: The Evaluation Phase -> How to send a Non-Implemented Control to Treatment.
