Inactivating workflow states
Inactivate a state instead of deleting it if you want to keep it for historical purposes, but you do not want users to access it. You cannot inactivate a state if an item is currently in the state. You can activate the state if you decide to use it again.
1. Choose Tools > Administration > Workflow.
The Configure Workflow dialog box opens.
2. Select an Item type.
3. Select a state and click Inactivate.
You are prompted to confirm the inactivation.
If the state is a resulting state for an event, it will no longer be available as a resulting state. If you activate the state later and want to use it as the resulting state for an event, you must select it in the Add or Edit Event dialog box.
4. Click Yes.
The state is inactivated.
To activate an inactive state, select it and click Activate.
