When an entity that is not a scheme, analyte, unit, biofield, job nor sample is requested to be created, then:
- If the preference is inactive or the preference setting is empty (default on deploy), and the entered code contains a character not in the ABCDEFGHIJKLMNOPQRSTUVWXYZ_01234567890 character set, then the entity creation does not proceed.
- If the preference is active and the preference setting is not empty, and the entered code contains a character not in the provided set of printable characters, then the entity creation does not proceed.
Typically the preference is not set at role or user level.
