I have a business process which is triggered by a workflow. The workflow sets business process variable and the link to that business process form is sent via email. The email recipient has to upload documents and submit which is reviewed by an approver (next stage within the form - a user task).
If the user submits the form again using the link within his email , how can i notify him that, he has already submitted the documents.
Or restrict him from submitting (is there a way in which we can control this)
Thank you
