• What is the cause and solution for SAP error message WZ152 - This method has no parameters ?

  SAP Error Message:
  
  WZ152 - This method has no parameters
  
  Cause:
  This warning message occurs when you try to call or reference a method in ABAP that does not have any parameters defined, but the call or reference expects parameters. Essentially, the method you are trying to use is defined without any importing, exporting, changing, or returning parameters, yet the code attempts to pass parameters to it.
  
  Explanation:
  
  In ABAP Objects, methods can have parameters (importing, exporting, changing, returning).
  If a method is defined without any parameters, calling it with parameters will trigger this warning.
  This message is a warning (WZ), not an error, so the program can still run, but it indicates a potential logical issue.
  
  
  Solution:
  
  
  Check the method definition:
  
  Go to the class builder (SE24) and inspect the method's signature.
  Confirm whether the method has parameters or not.
  
  
  
  Adjust the method call:
  
  
  If the method has no parameters, remove any parameters from the method call.
  
  
  Example:
  " Incorrect call if method has no parameters
  obj->method_name( param1 = value1 ).
  
  " Correct call if method has no parameters
  obj->method_name( ).
  
  
  
  
  Modify the method if parameters are needed:
  
  If the method logically requires parameters, add them in the method definition.
  Then adjust the method implementation and calls accordingly.
  
  
  
  Suppress the warning (not recommended):
  
  If you are sure the warning is harmless, you can suppress it, but better to fix the root cause.

  Summary:
  
  Cause: Calling a method with parameters when it has none defined.
  Solution: Remove parameters from the call or add parameters to the method definition.
  Check: Method signature in SE24 and adjust code accordingly.
