Hi,
You can check the duty called "Maintain purchase orders" to ensure that the necessary permissions are in place. For specific actions like "Finalize," you can use the related privileges that align with the required security roles. This setup will help control access and authorization effectively in the purchasing process.
What do you mean authorization button? is it workflow you are talking about? if so, in your screen shot there is one "Workflow" option from there user can approved/reject.
