When you type in the record and try to move to a new record, you receive a dialog box that has a warning message that says “You cannot add or change a record because a related record is required in the table ‘Patient’“. This is because there is a one to many relationship with referential integrity between the tables Patient and Session. This prevents an entry of a new PatientNum in the Session table without first having that PatientNum recorded in the Patient table.


Dialog warns of required related record in "Patient" table due to one-to-many relationship, enforcing referential integrity.
