A simple approval workflow can be created by setting a purchase limit on Orderer and Manager. When the Orderer or Manager places an order, an approval will be required by the Admin.
Start by navigating to the User Administration page. Click on the user you wish to set a purchase limit.
Enter a purchase limit for the user, if you input nothing there is no limit on their ordering, if you input $1 all the orders will require approval, then click "Update User".
Depending on the Admin's user setting for order notification, after an order is created, the Admin will receive an email notification and mobile app notification regarding the order that requires approval. The status of the order will also be "Needs Approval".
The Admin will open the order to view the details of the order and choose to approve or decline the entire order at that time it will get sent to the Supplier.
