You can mark an In-Progress workflow as complete without going through all the recipients. For this, you need to terminate the workflow. This is useful in the cases where a few recipients don't respond to the workflow or the remaining recipients are no more required.
Login with your enterprise admin credentials.
Click "Configurations" in left menu and click "Documents" under Documents & Signing options in Enterprise Configurations section.
Select the desired document package and click "Terminate workflow" in right panel.
A confirmation message will be displayed. Click Yes. The workflow will be terminated and the document package will be marked as "Completed". A recall notification will be sent to all those recipients with whom the document package was shared and they haven't processed it, i.e. the document exits in their inbox with the "Pending" status.
In order to terminate a workflow of your enterprise document, you must have the "Edit" rights on the "Enterprise Documents" settings, see details.
