• What is the cause and solution for SAP error message /STMC/CR_MSG878 - Error while checking class &1; wrong CONSTRUCTOR definition ?

  The SAP error message /STMC/CR_MSG878 indicates that there is an issue with the constructor definition in a class. This error typically arises when the constructor method of a class does not match the expected signature or is incorrectly defined.
  Cause:
  
  Incorrect Constructor Signature: The constructor may not have the correct parameters or may be missing required parameters.
  Access Modifiers: The constructor might be defined with an access modifier that does not allow it to be called from the context where it is being used.
  Inheritance Issues: If the class is inheriting from a superclass, the constructor of the superclass may not be properly defined or called.
  Syntax Errors: There could be syntax errors in the constructor definition that prevent it from being recognized correctly.
  
  Solution:
  
  
  Check Constructor Definition: Review the constructor method in the class definition. Ensure that it has the correct parameters and matches the expected signature.
  CLASS your_class_name DEFINITION.
    PUBLIC SECTION.
      METHODS: constructor IMPORTING iv_param TYPE your_type.
  ENDCLASS.
  
  CLASS your_class_name IMPLEMENTATION.
    METHOD constructor.
      " Constructor logic here

  ENDCLASS.
  
  
  Access Modifiers: Ensure that the constructor is defined with the appropriate access modifiers (e.g., PUBLIC, PROTECTED) so that it can be accessed from where it is being called.
  
  
  Check Inheritance: If the class is inheriting from another class, ensure that the constructor of the parent class is correctly defined and called in the child class.
  CLASS child_class DEFINITION INHERITING FROM parent_class.
    PUBLIC SECTION.
      METHODS: constructor.
  ENDCLASS.
  
  CLASS child_class IMPLEMENTATION.
    METHOD constructor.
      SUPER->constructor( ). " Call to parent constructor
    ENDMETHOD.
  ENDCLASS.
  
  
  Syntax Review: Look for any syntax errors in the constructor definition. Ensure that all keywords and structures are correctly used.
