Hi bob,
the system generated ID is to one way to identify the case or person. using
orgunit you mean the code for that organization unit. In india they have
generated a 16 digit ID based on Country, Province,District,Sub-district and
facility. but the problem with this is what happen if new district
or province is created. In norway the personal id number is
ddmmyy+sex+random number. I thougth we cloud use the same but increasing the
random number to avoid the duplicate. And its also useful that the person
dont have to remember all the 16 or 14 digit number. for the sake of
simplicity we used this method.
