Project Billing Invoice should be approved only by Manager and not Submitter
Project Billing Invoice should be approved by the Manager. The submitter should not be able to approve.
Currently the project billing invoice is submitted and goes into submitted status and the workflow notification is sent to the manager. The current situation is that the submitter is also able to approve the invoice but the requirement is that only the Manager should be able to approve it.
In InvoiceApprovalHumantask, Contract Invoice Single Approval Participant is enabled with workflow to go to the Manager and Contract Invoice Serial Approval Participants is enabled.
How do we achieve the requirement of only the Manager able to approve?
