You can use short messages to send important information to the users of an SAP system. You can either send the message to all users on all application servers, or only to the users who are logged on to a particular application server.
The system displays a message only once to each user during a logon session. Messages are displayed to users in the following ways:
A user must actively acknowledge a system message before she or he can continue working.
System Messageshas the following functions:
You can post as many messages as you wish. Messages can be more than one line long. This is described in detail in the section Creating and Sending System Messages.
Choose Edit ® Current messages or Archived messages to display either the active messages or the inactive, archived messages (messages that are past their expiration date, but are still available in the database).
You can alter the text and expiration date of any message (see Creating and Sending System Messages).
You can delete an individual message or all messages. To delete a specific message, position the cursor on it and choose Delete. You can also use Edit ® Delete to do this (either for an individual message or for all system messages).
Deleted messages are then removed from the database, which means they are also no longer kept with the archived messages.
Normally, you create system messages interactively. However, it is also possible to do this from a program. See Creating a System Message Under Program Control for further details.
