  2. Click Tables
  3. Go to File, Preview
  4. Choose Code Table Report
  5. Mark the box to 'Include inactive table entries'
  6. Click Preview

  8. Run this for Admissions Office, Registrar's Office, and Student Billing

To prevent the error in the future, if the value is left as Inactive, ensure that no default sets are being used with the inactive table entry and that no User Options are set to use the value as a default.
