Ok, so when I saw the new Save and Continue button option I thought it was exactly what the users have been wanting for a long time - save their work on the form then continue working on it (or not), but not Submit it for workflow processing.
The form I am modifying is a Financial project approval form, so up until now the user fills in the form, clicks the submit button and the item is created and the workflow for Approval / Rejection processing is initiated. Apparently the Save and Continue button does much the same: item is saved to the list, workflow started, but then the form is re-opened onscreen for the user to continue editing even though the workflow has now been started.
I'm obviously missing something - how can I allow the user to save the form but not have the workflow initiated until they click on the Submit button?
Thanks.
