Messages in dialog processing

For program execution in dialog processing, the behavior of messages, according to the dialog modules or event blocks in which they are sent, is displayed in the table below:

Processing block          Message type

If a different message type is specified under a message type "A", "E", "I", "S", "W" or "X", the original message type is converted to this type and the message is issued according to this type. A number under a message type indicates processing according to the following list:

  1. The message is displayed in a dialog box. After the dialog box is exited, the program is terminated and processing returns to the calling position of the first program of the current call sequence. All internal sessions of the call chain are deleted and a database rollback is performed.
  2. PAI processing is interrupted and the system returns to the current screen without triggering the event PBO. The message is displayed in the status bar of the current window as standard. If the error message is sent in a dialog module that is called in the dynpro flow logic outside a process chain defined with CHAIN following a FIELD statement, the input field specified after FIELD is the only field that is ready for input. If the error message is sent in a dialog module that is called within a process chain defined with CHAIN, all fields specified after FIELD in the process chain are ready for input. After a user action, PAI processing is continued at the point described under Handling of messages for the PAI event.
  3. The message is displayed in a dialog box. After the dialog box is exited, the program is resumed after the statement MESSAGE.
  4. The program is continued after the statement MESSAGE. The message is displayed as standard in the screen of the next dynpro in the status bar of the current window.
  5. PAI processing is terminated and returns to the current screen without triggering the event PBO. The message is displayed in the status bar of the current window as standard. The fields described under point 2 are ready for input. If the user confirms the current field content using the Enter key without entering a new value, the program is resumed after the statement MESSAGE. If the user enters one or more new values, processing is resumed after a user action as described under point 2.
  6. The program is terminated, a database rollback is executed, and the runtime error MESSAGE_TYPE_X is triggered. The short dump of the runtime error is displayed, which contains the ID, the short text, and the long text of the message.
  7. The sending of error messages is not permitted during POH and POVprocessing and the handling of a function code of type "E". This triggers an untreatable exception.
  8. Selection screen processing is interrupted and the system returns to the current selection screen without triggering the event AT SELECTION-SCREEN OUTPUT. The message is displayed in the status bar of the current window as standard. The input fields of the selection screen are ready for input that were specified by the additions of the statement AT SELECTION-SCREEN of the current event block. After a user action, selection screen processing is continued with the current selection screen event. Previous selection screen events are not triggered.
  9. Selection screen processing is interrupted and the system returns to the current selection screen with triggering the event AT SELECTION-SCREEN OUTPUT. The message is displayed in the status bar of the current window as standard. The fields described under point 8 are ready for input. If the user confirms the current field contents with the Enter key without entering a new value, the program is resumed after the statement MESSAGE. If the user has entered one or more new values, selection screen processing is resumed after a user action as described under point 8.
  10. The event block of the current list event is terminated and the list level at which the list event was triggered remains displayed. The message is displayed in the status bar of the current window as standard.
  11. The program is terminated and an empty screen is displayed with an empty GUIstatus. The message is displayed in the status bar of the current window as standard. After a user action, processing returns to the calling position of the program.
  12. As of release 6.40, the program is terminated with the runtime error SYSTEM_LOAD_OF_PROGRAM_FAILED. Before release 6.40, the system behaved according to the context in which the program was loaded, whereby the context after a call with SUBMIT is handled in the same way as the context PBO.

While a message is displayed, the user can display the long text, if applicable, by a single click with the mouse on the Help button if the message is displayed in a dialog box, or by clicking in the status bar. If no long text is defined, it is generated using the content of the short text.
