When creating an overview statement you have the opportunity to save it without submitting it. This keeps it in a draft state which isn't visible to the individual you wrote it for or your organisation's leaders in reports.
1. Head back to Manage and Overview Statements, there is a column for Completed? If this says No click back into the statement's title and you'll find Edit Overview Statement.
2. Head down to the foot of the page and check the box Mark this overview statement as complete? then press Save and that's it.
3. The individual will be notified and be able to respond and your organisation's leaders will be able to access it in their reports.
