Alliance Corp's approval policy requires the number of approvers to be based on the Item category. If the total amount of all items within a requisition with Item category "IT" is less than 1000 USD, then the IT manager needs to approve it. But if the total amount of IT category items within a requisition exceeds 1000 USD, then the IT manager, IT director, and CIO need to approve the document. For any other purchasing categories below 1000 USD, the purchasing manager approves it; and anything above 1000 USD, the procurement VP approves. Approval policy at Alliance Corp is configured to use the attribute type of "Summation" based on the IT category.
