Maintaining Messages (SAP Library - BC ABAP Workbench Tools)

Maintaining Messages

Messages allow you to communicate with users from your programs. They are mainly used when the user has made an invalid entry on a screen.
To send messages from a program, you must link it to a message class. Each message class has an ID, and usually contains a whole set of message. Each message has a single line of text, and may contain placeholders for variables.
All messages are stored in table T100. You create and edit them using Transaction SE91. Once you have created a message, you can use it in the MESSAGE statement in a program.

For further information about messages, see the messages section of the ABAP Programming Guide.

Starting the Message Maintenance Transaction

Using forward navigation from the ABAP Editor.

You can display the messages for your program from the ABAP Editor by choosing Goto ® Messages. The Maintain Messages screen appears. By default, the system display the message class linked to the current program.

You can also enter Transaction SE91.

If you choose Goto ® Messages from the ABAP Editor and your program does not have a defined message class, the system assumes you want to browse an existing class and prompts you for a message class ID.
