CSP Workbench Actions and Notifications

Learn what tasks and notifications mean in the Coupa Supplier Portal Workbench.

Different events that happen in an account can trigger notifications or tasks. The Coupa Supplier Portal (CSP) Workbench allows suppliers to see what actions are required on their end, as tasks that can be done in the CSP.

Notifications are the way Coupa keeps you informed about new information or changes related to your account. You can receive notifications through email or SMS. Some notifications are now shown in the CSP Workbench. 
For more information about managing notifications in your email or SMS, see View and Manage Notifications.

Tasks require an action in order to be completed. These appear on your workbench when Coupa or their customers needs you to take an action.
For more information, see Manage the CSP Workbench.
