Working with Program Messages 

You can assign a message class to any ABAP program. A message class has an ID nn where nn can be any two alphanumeric characters. A message class contains one or more messages.

You can display the messages for your program in the Editor. Choose Goto ® Messages from the Editor to display the Maintain Messages screen. By default, the system displays the messages for the current program:

If you choose Goto ® Messages 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. You can also reach the Maintain Message Class screen by choosing Development ® Programming environ. ® Messages from the Workbench's initial screen.
