What Is Message Class?
Message classes are like pockets in your pants. They hold all the little things you need to get the job done. Unlike our pants, message classes are for more than just keeping stuff. They're also how you communicate with users. Message classes are your go-to tool to let users know that they've entered a program incorrectly or want them to know what happens after they click a button. Message classes can hold text messages (like "You've entered the wrong number"), but they can also keep whole paragraphs of information and images! Message classes are highly flexible, and the data you can store is limited only by your imagination. You can store text data in a message class and use message classes to communicate with any SAP object. You can write your message class or use one of the standard message classes. You can use a combination of both. The only requirement is that the message class must have a unique message ID. The message class is a collection of messages that can reuse in any custom application. SAP provides message classes, but you can also create your own. They're most useful when adding error messages to your screen. Message classes are like people. Some are born to help you, while others are more trouble than they're worth. The good news is that developers can apply existing message class messages in their custom applications. SAP provides the flexibility to create custom message classes and messages, so you can make it happen if you need a message that's unlike any other. The most common use of message classes is in error-handling techniques. That's because they let your application know what happened when something went wrong so you can figure out what happened and fix it!
