I'm looking for a little bit of best practice / guidance here.
When a form is submitted, I want to stop the initiator from editing the form to avoid people changing details after it has been through the approval step. I do this by setting permissions on the item to read-only for all users. However, after that it appears that the workflow can't update the status, as I assume it's still running under the profile of the initiator and thus loses the ability to update.
Suggestions please? How do others stop the user from changing the form once submitted?
