  • FRM-40401 No changes to save error

    FAQ:

    I have updated a table from the form and written a update statement in the when-button-pressed trigger.
    while the code is working fine and the table is updated but iam finding this error in the console frm-40401 no changes to save. pls help me why it is coming and what affect it have on my form. i had suppressed this message by writing on-error trigger on form level.

     

    You can bypass this by raising the message level.

    Code:

    DECLARE
      -- Capture the original message level, to reset afterwards.
      v_message_level PLS_INTEGER := :SYSTEM.MESSAGE_LEVEL;
    BEGIN
      -- Raise the message level above 5, avoid information messages.
      -- Read the Forms help file for more info
      :SYSTEM.MESSAGE_LEVEL := 5;

      COMMIT_FORM;

      -- Reset the message level to the original value
      :SYSTEM.MESSAGE_LEVEL := v_message_level;
    END;

    The message means that no database items in the Form have changed, so the BLOCK_STATUS is still in QUERY_STATUS. As a result, for Forms default transaction processing, there's nothing to save.
    Alternatively, you can set the record status manually to changed_status, thus avoiding the message.

     

    Processing:

    DECLARE
      -- Capture the original message level, to reset afterwards.
      l_message_level PLS_INTEGER := :SYSTEM.MESSAGE_LEVEL;
    BEGIN
      -- Raise the message level above 5, avoid information messages.
      -- Read the Forms help file for more info
      :SYSTEM.MESSAGE_LEVEL := 5;
        kol_osfm_move_trans_private.insert_row;
        do_key('COMMIT_FORM');
      -- Reset the message level to the original value
      :SYSTEM.MESSAGE_LEVEL := l_message_level;
    END;
