How does one suppress or customize error messages in Forms?

One can either set the message level using the system variable SYSTEM.MESSAGE_LEVEL or trap errors using the ON-ERROR or ON-MESSAGE triggers.

MESSAGE_LEVEL:

Set to 0, 5, 10, 15, 20, 25 to suppress all messages with severity below this level. The default level is 0. Messages with a level higher than 25 cannot be suppressed. See the "Forms Error Messages Manual" for more details about the various MESSAGE_LEVEL's:

* 0 - Default value. All types of messages from the other levels of severity.
* 5 - Reaffirms an obvious condition.
* 10 - Indicates that the operator has made a procedural mistake.
* 15 - Declares that the operator is attempting to perform a function for which the form is not designed.
* 20 - Indicates a condition where the operator cannot continue an intended action due to a problem with a trigger or another outstanding condition.
* 25 - Indicates a condition that could result in the form performing incorrectly.
* >25 - Indicates a message severity level that you cannot suppress via the SYSTEM.MESSAGE_LEVEL system variable.

Examples:

:SYSTEM.MESSAGE_LEVEL := '25';
COMMIT;
:SYSTEM.MESSAGE_LEVEL := '0';

/* For suppressing FRM-40100: At first record. */
:SYSTEM.MESSAGE_LEVEL := '5';
FIRST_RECORD;
:SYSTEM.MESSAGE_LEVEL := '0';

/* For suppressing FRM-40350: Query caused no records to be retrieved. */
:SYSTEM.MESSAGE_LEVEL := '5';
EXECUTE_QUERY;
:SYSTEM.MESSAGE_LEVEL := '0';
