'''Person''' needs to be adjustable for the Load - Input approach for the first record. After the first use it becomes locked so that this assessment cannot be reallocated to anyone else. The default is False. By setting this value to true, the assessment could be assigned to anyone else. It is strongly advised not to change this field. However if an assessor makes a genuine mistake on the assessment and assess the wrong person. Changing this flag on a temporary basis to fix the mistake and then putting it back, can be labour saving.
