  SAP Error Message WER120
  
  Error Message Text:
  WER120: "The message is not assigned to the message class"
  
  Cause:
  The error WER120 occurs when an attempt is made to call or display a message using a message number that does not exist in the specified message class. In SAP, messages are grouped into message classes, and each message class contains a set of message numbers with corresponding texts. If the program tries to access a message number that is not defined in the given message class, SAP raises this error.
  
  Typical Scenario:
  
  A developer or program calls a message using the syntax:
  
  MESSAGE e123(zmsgclass).
  
  but message number 123 does not exist in message class ZMSGCLASS.
  This can happen due to:
  
  Typographical error in the message number or class.
  The message number was never created or was deleted.
  The message class is incorrect or misspelled.
  
  
  
  
  Solution:
  
  
  Check the message class and number:
  
  Go to transaction SE91 (Message Maintenance).
  Enter the message class (e.g., ZMSGCLASS).
  Verify if the message number (e.g., 123) exists.
  
  
  
  If the message number does not exist:
  
  Create the missing message number with the appropriate text.
  Or correct the program to use an existing message number.
  
  
  
  If the message class is incorrect:
  
  Correct the message class name in the program or configuration.
  
  
  
  Check for typos:
  
  Ensure the message class and number are correctly spelled and formatted.
  
  
  
  Transport and system consistency:
  
  If the message was recently created, ensure it has been transported to the system where the error occurs.
  
  
  
  
  Additional Information:
  
  Transaction SE91 is used to maintain message classes and messages.
  Message classes are typically created by developers or basis teams.
  Messages are used for error, warning, information, success, or abort messages in ABAP programs.
  The message number is always a three-digit number (e.g., 001, 123).
  The message class is usually a short text (up to 20 characters).
