in se91 we are creatimg nessages .for every message beside 1 chck box is there.(self explanatory). what is the meaning of tha check box.
Check box is used to say the message is self explanatory or not. If the message is not self-explanatory, then a separate long text has to been maintained to see the detailed description of the message. By default, the Self-Explanatory check box would be checked.
If you want to test this, create a long-text for message by de-activating the self-explanatory option and save it. Then enable the Self-explanatory check box which would automatically prompt you to maintain or delete the existing long text for the message.
