A fixed [lexicon|LEXICON] is a lexicon that has values supplied to you that are part of the system [seed data|SEED DATA].  The values that a fixed lexicon imparts are fixed inasmuch as there is usually programming that is looking for specific values.

Rules regarding fixed lexicons:
* If you delete any fixed lexicon values, they will be re-added when this [seed data|SEED DATA] is next reloaded
* Changing the descriptive meaning (display value|LEX_ABBREVIATION) of this lexicons is discouraged because:
** The original descriptive meaning will be restored when you reload this seed data next
** There may be specific programing that will be confounded by a user's expectation (given the change in meaning)
* Adding new values to this lexicon is discouraged because:
** Any values added will be removed when the seed data is next reloaded
** There will be no programming to support your additions.

If you have a need to add to a fixed lexicon, it is recommended you contact Support through the Customer Care system.
