If you are a proxy author and have finished writing a document or questionnaire (already clicked Finished Writing), you can send a request to the owner to submit the document/questionnaire for review.
Note: Requesting submission for review sends an email notification to the document owner or questionnaire owner, but it does not add a task to the owner's My Tasks list. You can add an owner task in the Settings step of the Properties Wizard (see Adjusting Basic Settings).
