The workflow discussion thread
To every workflow is associated a discussion thread. The approver and the requester can exchange comments as soon as the request has been submitted and up to the final step of the workflow.
Activities > Requests > Requests to process
When processing the requests, the approver can send a comment to the requester.
Entering a comment
To enter a comment, click on the
icon ("status" column), fill in the field and save.

The discussion thread allows the requester and the approver to exchange comments without multiplying emails. The approver can, for example, enter a comment to ask the requester to edit his timesheet entries before returning the request. The requester will thus understand why his timesheet has not been validated.
The discussion thread is available for all workflows.
Discussion thread and notification emails
Comments are included in notification emails, whether for the requester or for the approver.
