If a payment is entered incorrectly, you can void it on a student's record.
For example, if Sally entered a family two times and attached money to both records. When she discovered her mistake, she wanted to combine the family records so that only one record for the family existed.
To do this, Sally voided the invoices and payments for the record that contained the least transactions. She then entered the invoices and payments to the family record she planned to keep. Next, Sally deactivated the family record she no longer needed, because a user cannot delete a family record that invoices and payments have been posted to, even if the transactions are voided.
