• What is the cause and solution for SAP error message WER164 - Method &1 does not have parameters ?

  SAP Error Message:
  
  WER164 Method &1 does not have parameters
  
  Cause:
  This error occurs when an ABAP program or a method call tries to pass parameters to a method that is defined without any parameters. In other words, the method being called does not expect any input or output parameters, but the call statement includes parameters.
  For example, if a method METHOD1 is defined as:
  METHOD method1.
    " No parameters defined
  ENDMETHOD.
  and the call is made like:
  CALL METHOD object->method1
    EXPORTING
      param1 = value.
  then the system raises the error WER164 because method1 does not have any parameters.
  
  Solution:
  
  
  Check the method definition:
  
  Go to the class builder (transaction SE24) or wherever the method is defined and verify if the method has parameters defined (IMPORTING, EXPORTING, CHANGING, or RETURNING).
  
  
  Adjust the method call:  
  
  If the method has no parameters, remove any parameter passing in the method call.
  If parameters are needed, modify the method definition to include the required parameters.
  
  
  
  Correct the call statement:
  
  For a parameterless method, call it simply as:
  CALL METHOD object->method1.
  
  
  Check for interface changes:
  
  If the method belongs to an interface or a superclass, ensure that the method signature matches the implementation and the call.
  
  
  
  Related Information:
  
  Transaction SE24: Class Builder to check method definitions.
  ABAP Documentation: For method parameter definitions and calling conventions.
  Common scenarios:  
  
  Calling a method from a generated proxy or standard SAP class where the method signature has changed.
  Copy-paste or code merge errors where method calls were not updated after method signature changes.
  
  
  Debugging tip:
  
  Use the ABAP debugger or syntax check to identify the exact method and call causing the issue.
  
  
  Summary:
  
  Error WER164 means you are passing parameters to a method that does not accept any.
  Fix: Remove parameters from the method call or add parameters to the method definition as required.
  
  
  If you provide the method name and the code snippet where the call is made, I can help you with a more specific correction.
