Generally, a file is not maintained by LANSA if it was created by, and belongs to, an application created outside of LANSA.
If such a file (frequently referred to as an OTHER file) needs to be accessible within the LANSA system, the definition must be loaded into LANSA. At the same time, any alterations to the definitions must be prohibited from within LANSA, as this could affect the system which is maintaining it.
