To create a message, point to New in the Explorer menu and choose Message. The Messages window will appear.
Enter the message ID and the message. If the ID is already used, the message associated with it will be displayed and can be edited. To delete an existing message, click Delete.
If you are adding messages to an application that integrates with Microsoft Dynamics GP, be sure the message IDs for messages you create are 22,000 or greater. Otherwise, your messages won’t be extracted when you package your application.
Click Save to save the message.
