Create a Requisition

Learn about the requirements and steps involved in creating a requisition through the ARC System at Columbia University. 

Already Know How?

Go to the ARC Portal to login to ARC and create a requisition.


A requisition is a formal request to buy a good or service and allows users to create either an autosource purchase order for Supplier Guide based purchases or a central purchase order.

  • Create a requisition before placing an order with a vendor
  • Check if prior department/budget approval is necessary
  • Verify funding and approval for a purchase prior to initiating or approving a requisition

Once a requisition has received final approval by the Purchasing Department, ARC generates a purchase order and dispatches it to the supplier via email, so be sure to include the correct vendor email on the requisition. 

Purchasing Methods and Requirements

Not all purchasing methods require a requisition. Please refer to the Purchasing Process Quick Guide for details on when to use the following purchasing methods:

  • Voucher Only
  • P-Card
  • Requisitions for Auto-Sourced (Direct) Purchase Order (PO)
  • Requisitions for Central PO
  • For items not using UwPA

ARC Roles and Considerations

Requisitions are requested by a Requestor and then entered into ARC by a Requisitioner. The requisition is then passed on to multiple approvers.

On certain transactions, prior approval may be necessary. Approvers cannot approve their own transactions unless they have security access that permits them to bypass segregation of duties.
