  The SAP error message COM_PME_PARSER065 indicates that there is a syntax error in a class entry, specifically that an expression is required in the form <(...)...>. This error typically occurs in the context of ABAP programming, particularly when dealing with class definitions or method implementations.
  Cause:
  The error is usually caused by one of the following issues:
  
  
  Incorrect Syntax: The syntax used in the class definition or method implementation does not conform to the expected format. This could be due to missing parentheses, incorrect use of operators, or other syntactical errors.
  
  
  Missing Expressions: The error suggests that an expression is expected but not provided. This could happen if you are trying to define a method or a class attribute without providing the necessary expressions or parameters.
  
  
  Improper Use of Generics: If you are using generic types or interfaces, the syntax must be strictly followed. Any deviation can lead to this error.
  
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check Syntax: Review the class definition or method implementation for any syntax errors. Ensure that all expressions are correctly formatted. For example, if you are defining a method, ensure that the parameters are enclosed in parentheses and that the method signature is correct.
