We have just pushed out an update to Samanage that enables you to display any pending approvals on incidents which originate from the Service Catalog.
This new column - ?Pending Approval? is not displayed by default and can be added by using the ?wrench? icon.
Once the column has been added, it will display any pending approvals and who they are pending on - see screenshot below.
At your service,
The Samanage Team
