• What is the cause and solution for SAP error message WER215 - Message number can only contain numerical characters ?

  SAP Error Message:
  
  WER215 - Message number can only contain numerical characters
  
  Cause:
  This error occurs when you try to enter or define a message number that contains non-numeric characters in SAP. In SAP message classes, the message number must be strictly numeric (usually a 3-digit number, e.g., 001, 100, 999). If you enter letters, special characters, or any non-numeric characters in the message number field, the system raises this error.
  
  Explanation:
  
  Message classes in SAP are used to group messages logically.
  Each message within a class is identified by a message number.
  The message number must be numeric because SAP internally uses it as an integer identifier.
  Entering alphabets or special characters violates this rule, triggering the WER215 error.
  
  
  Solution:
  
  When creating or maintaining messages in transaction SE91 (Message Maintenance), ensure that the message number field contains only digits (0-9).
  Use numbers in the range allowed by SAP (usually 001 to 999).
  Remove any letters, spaces, or special characters from the message number field.
  If you are importing or copying messages programmatically, validate the message number format before saving.

  Message Class: The message class is a 2-character alphanumeric identifier, but the message number must be numeric.

  If you are working with custom messages, always follow the numeric-only rule for message numbers.
  For more details, you can check SAP Notes or the SAP Help Portal related to message maintenance.
