The Marital Status and Maiden Name fields are displayed in the Demographics section of student/applicant records when a particular business rule is selected. If you are receiving this exception when importing records, the business rule is not marked. To resolve this, follow these steps:

1. In Education Edge or Blackbaud Student Information System, go to Configuration, Business Rules, General.
2. Mark the checkbox for 'Display Marital Status and Maiden Name fields for Students and Applicants.'

Once this is marked, you will be able to import students/applicants successfully.
