• What is the cause and solution for SAP error message EMMA179 - Class &1 does not inherit from superclass &2 ?

  The SAP error message EMMA179 indicates that there is an issue with class inheritance in ABAP (Advanced Business Application Programming). Specifically, it means that the class you are trying to use (denoted as &1) does not properly inherit from the specified superclass (denoted as &2). This can occur in various scenarios, such as when you are trying to instantiate a class or when you are using polymorphism.
  Cause
  The error can be caused by several factors:
  
  Incorrect Class Declaration: The class &1 may not be declared to inherit from the superclass &2 in its definition.
  Typographical Errors: There may be a typo in the class name or the superclass name.
  Class Visibility: The superclass may not be visible to the class you are trying to use, possibly due to access restrictions.
  Changes in Class Structure: If the superclass has been modified or deleted, it may lead to this error.
  
  Solution
  To resolve the EMMA179 error, you can follow these steps:
  
  
  Check Class Definition:
  
  Open the class &1 in the ABAP Workbench (SE80 or SE24).
  Verify that it correctly inherits from the superclass &2. The inheritance should be defined in the class declaration section.
  
  
  
  Correct Any Typos:
  
  Ensure that there are no typographical errors in the class names. Check both the class and superclass names for accuracy.
  
  
  
  Review Access Modifiers:
  
  Ensure that the superclass &2 is accessible to the class &1. If the superclass is declared as private or has restricted visibility, it may not be accessible.
  
  
  
  Check for Changes:
  
  If the superclass has been modified or deleted, you may need to update the class &1 to reflect these changes. If the superclass is no longer available, you may need to redefine the class or find an alternative superclass.
  
  
  
  Recompile the Classes:
  
  After making any changes, recompile both the class &1 and the superclass &2 to ensure that the changes take effect.
  
  
  
  Check for Dependencies:
  
  If the class &1 is part of a larger application or module, ensure that all dependencies are correctly defined and that there are no missing components.
