(<pid> not found, generate [max+1])
If the <patient_id> source / value pair has not been added to the mapping table, a new PATIENT_NUM with value max(patient_num)+1 should be generated and all the PATIENT_NUMs for this patient will receive this value. The new patient number must also be added to the PATIENT_DIMENSION table.
Example:
New <patient_id> source / value pair = 'EMPI' / 1000000
Select max(patient_num) from patient_mapping = 527
New patient_num = max(patient_num) + 1 = 528
