=== Wrong Serial Numbers ===
=== Wrongly entered serial numbers ===
Sometimes the wrong serial number gets assigned to a patient. Due to the way HanDBase uses the serial number to relate records in different tables, '''serial numbers can not be changed once a patient has been entered into the PDA'''. If a serial number is changed, some or all of the related records such as diagnoses may go missing.
