If amendments have been made to a file definition, this screen will be presented after the Exit or Cancel function key has been used from the file definition menu:
Enter YES to commit the file definition amendments to the LANSA system. Enter NO to drop all amendments. If NO is entered the file definition will revert to the form it had prior to the amendments being made.
After amendments have been made to the file definition it is then necessary to recreate the actual IBM i database file(s) from the amended definition. Refer to Making a New or Amended File Definition Operational for a detailed description of how this is done.
