• What is the cause and solution for SAP error message SEO_ADT004 - Class implementation part not found ?

  The SAP error message SEO_ADT004: Class implementation part not found typically occurs in the context of ABAP development, particularly when working with ABAP Development Tools (ADT) in Eclipse. This error indicates that the implementation part of a class is missing or not properly defined.
  Causes:
  
  Missing Implementation: The class has been defined, but the implementation section (the methods) has not been created or is missing.
  Incorrect Class Definition: The class might be defined incorrectly, or the implementation might not be linked properly to the class definition.
  Transport Issues: If the class was transported from another system, there might have been issues during the transport process that caused the implementation to be lost.
  Development Environment Issues: Sometimes, issues with the ADT or Eclipse environment can lead to this error, such as caching problems or outdated metadata.
  
  Solutions:
  
  
  Check Class Implementation:
  
  Open the class in the ABAP editor (SE24 or SE80).
  Verify that the implementation part exists. If it does not, you will need to create it.
  If the implementation exists but is not linked, ensure that it is properly defined.
  
  
  
  Create Implementation:
  
  If the implementation part is missing, you can create it by navigating to the class definition and selecting the option to create the implementation part.
  Implement the necessary methods as required.
  
  
  
  Check Transport Requests:
  
  If the class was transported, check the transport logs for any errors or issues.
  Ensure that all related objects were transported correctly.
  
  
  
  Refresh ADT:
  
  Sometimes, simply refreshing the ADT environment can resolve the issue. Try closing and reopening the project or restarting Eclipse.
  
  
  
  Clear Cache:
