• What is the cause and solution for SAP error message WSTRN033 - Specify a CL_WSTN_STYLE object ?

  SAP Error Message:
  
  WSTRN033 Specify a CL_WSTN_STYLE object
  
  Cause
  This error occurs in the context of SAP Web Dynpro or Web Services when a style object of class CL_WSTN_STYLE is expected but not provided or incorrectly specified. The class CL_WSTN_STYLE is used to define styles (such as fonts, colors, and other formatting) for Web Dynpro components or Web Services.
  Typically, the error arises because:
  
  A method or function expects a parameter of type CL_WSTN_STYLE (or a reference to it), but the caller has passed NULL or an incorrect object.
  The style object has not been instantiated before being passed.
  The style object is missing or not properly assigned in the Web Dynpro component or Web Service configuration.
  
  
  Solution
  To resolve the error:
  
  
  Instantiate the Style Object Properly
  
  Before passing the style object, create an instance of CL_WSTN_STYLE. For example:
  DATA: lo_style TYPE REF TO cl_wstn_style.
  
  CREATE OBJECT lo_style.
  
  
  Pass the Style Object to the Method
  
  Ensure that the method or function that requires the style object receives the instantiated object:
  CALL METHOD some_method
    EXPORTING
      style = lo_style.
  
  
  Check the Web Dynpro or Web Service Configuration
  
  If the error occurs during runtime in a Web Dynpro application or Web Service, verify that the style object is correctly assigned in the component controller or context.
  
  
  Review the Code or Configuration Where the Style is Used
  
  Look for places where the style object is expected and ensure it is not NULL or missing.
