Within the new procurement system users are defined by at least one of the following 'roles':
- Shopper - a user who may create purchase requisitions (known as shopping carts) and the ability to complete forms. Shoppers will assign their 'shopping carts' to the appropriate Requestor or Approver.
- Requestor - a user who, in addition to creating purchase requisitions (known as shopping carts) and completing forms, has the ability to enter accounting codes and submit requisitions (carts) into the workflow process for approval.
- Approver - a user who, in addition to the above mentioned capabilities, approves requisitions and forms submitted to them.
