For example, when a user blocks himself out and receives a message :
"User blocked. Contact system administrator"
You can open a repair and change the message in Message class 00.
This can be done in transaction SE91 -
Message Maintenance.
Messages allow you to communicate with the 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 (e.g. & & & - three variables).
All messages are stored in table T100.
Once you have created a message, you can use it in the MESSAGE statement in a
program.
