• What is the cause and solution for SAP error message WER169 - Class &1 does not have any public static methods ?

  SAP Error Message:
  
  WER169 Class &1 does not have any public static methods
  
  Cause:
  This error occurs when the system tries to call a public static method of a class, but the specified class does not contain any public static methods. The placeholder &1 is replaced by the actual class name at runtime.
  Common scenarios include:
  
  The class exists but only has instance methods (non-static).
  The class is empty or does not have any methods defined as public static.
  A typo or incorrect class name is passed to a function or method call.
  The class is intended to be used differently (e.g., as an instance class rather than static utility class).
  
  
  Explanation:
  In ABAP, static methods are called on the class itself without creating an instance. If a program or function module expects to call a static method but the class does not have any, this error is raised.
  Example:
  CALL METHOD cl_example=>some_method.
  If cl_example does not have a some_method defined as public static, the error WER169 will occur.
  
  Solution:
  
  
  Check the class definition:
  
  Go to SE24 (Class Builder).
  Enter the class name from the error message.
  Check if there are any methods defined as public static.
  
  
  
  Add a public static method if needed:
  
  If the class is supposed to have a static method, define it accordingly.
  Example:
  CLASS cl_example DEFINITION.
    PUBLIC SECTION.
      CLASS-METHODS some_method.
  ENDCLASS.
  
  
  
  
  Correct the method call:
  
  If the method is not static, create an instance of the class and call the instance method.
  DATA(lo_example) = NEW cl_example( ).
  lo_example->some_method( ).
  
  
  
  
  Verify the class name and method name:
  
  Ensure that the class name passed is correct and the method exists.
  Check for typos or incorrect parameters.
  
  
  
  Check the calling program or function module:
  
  If the error occurs inside a standard SAP program or function module, check OSS notes or SAP support for patches or corrections.
  Sometimes, the error can be caused by custom code or enhancements.

  SAP Notes: Search for WER169 in SAP Support Portal for any known issues or patches.
  
  
  Summary:
  
  Cause: The class specified does not have any public static methods.
  Solution: Define a public static method in the class or change the method call to use an instance method.
  Check: Class definition, method visibility, static vs instance method usage, and correctness of class/method names.
