About application message construction

Use application messages to display these types of information:

  • Information or questions that require responses from the user
  • Warnings about potential problems or conditions
  • Error conditions within the application environment or operations
  • System responses to user actions
Note:  The types of application messages described here are generated through application database code (stored procedures, triggers, etc.) and/or in the IDO layer (IDO extension class assemblies, etc.). Messages that are generated at the client level are not applicable there and do not reference or use the messages that are contained in those application tables.  

Application messages are stored in the system and are invoked in response to user or system operations. Messages can be constructed with both literal strings and substituted variable values, which are inserted into the message when it is invoked.

Messages are identified and invoked with a unique message number that is assigned to the message when it is constructed.
