Operation not performed" typically occurs when you are trying to use a character that is not permitted as the first character in a field or identifier within the SAP system. This error is often encountered in various contexts, such as when naming variables, fields, or other identifiers in ABAP programming or when entering data in certain fields.
  Cause:
  
  Invalid Character: The '@' character is not allowed as the first character in identifiers or certain fields in SAP. This restriction is in place to ensure that identifiers conform to naming conventions.

  Example:
  
  Instead of @myVariable, use myVariable or _myVariable.
  
  
  
  Check Input Fields: If this error occurs while entering data in a field, review the input to ensure that it does not start with an invalid character. Modify the input accordingly.
