The College of Chemistry Business Office maintains a data-table called the 'Cost Center List'. The 30-character accounting chartstrings used in the BFS system for purchasing, payroll, and recharges are referenced by a simple 4-digit 'cost-center'. By using your cost-center in College recharge systems and on Purchase Order Requests, you can make charges against your full chartstring without having to remember all 30 characters.
All College recharge systems REQUIRE the use of a cost-center, as do Purchase Order requests for Campus recharges (such as The Scholar's Workstation orders). A cost-center is not required for Accounts Payable purchase orders, but it does assist processing of your order.
