If an AutoFill Keyword Set uses MRN, Master Patient Index, or Chart ID as the primary Keyword Type, this Keyword Set should not be allowed to expand for back-end import processes (for example, DIP, COLD). These import processes cannot determine which AutoFill Keyword Set to expand when multiple sets have the same primary value.
Make sure the Expand AutoFill Keyword Sets option is disabled in each process's configuration options. This will help ensure data integrity if identifiers are allowed to overlap.
