SAP Messages
SAP messages are the system’s coded notifications, errors, warnings, information, each with a class and number. This reference explains understanding and finding them.
Messages are how SAP tells you what is wrong; reading them precisely (class + number + text) is the fastest route to a cause, and message references are heavily searched when troubleshooting.
- Double-click a message (or use the long text) to see details/cause.
- Use SE91 to view message classes and texts.
- Note the class + number to search SAP Notes/help for known issues.
- Watch out: the message type decides whether the same text informs, warns or terminates the program.
What it is
A message (e.g. "M7 021") has a message class (M7) and number, with types Error (E), Warning (W), Information (I), Success (S), Abort (A). The message text often includes placeholders filled at runtime. Messages drive validations and user feedback throughout SAP.

- Use
SE91to view message classes and texts. - Note the class + number to search SAP Notes/help for known issues.
- In debugging, set a breakpoint on a specific message to find where it is raised.
