Field help (ACODADR) 

This code is used to identify the various addresses associated with the managed record (user, company, site, business partner of any description, etc.).
Each address code is unique to a given record.
In general, it is mandatory to enter an address for each record, and one of them must be declared as the default address using the corresponding box.

You cannot modify or delete an address code when it is used at the level of a Bank ID number or for a contact.
In this case, to be able to modify or delete an address code, you first need to remove it from the level of the Bank ID number or contact.
