Reminder: Be sure to select either NorthAmer or Intl Libraries as the Billing Category. That way the billing is correct.
If you forget or find a request that was coded incorrectly, in ILLiad 7.4 you can always do an “UNDO OCLC SHIPPED” from the Process tab. In ILLiad 8.0, click on the OCLC tab at the top and click the UNDO SHIPPED, red icon.
