  The SAP error message 5B712 indicates that there is an issue with the implementation of a class in relation to an interface in the context of an infotype. Specifically, the message states that the class specified does not implement the required interface.
  Cause:
  This error typically occurs when:
  
  A class that is supposed to implement a specific interface does not do so. This can happen if the class was modified or if the interface was changed and the class was not updated accordingly.
  There may be a mismatch between the expected interface and the actual implementation in the class.
  The infotype configuration may be incorrect, leading to the system trying to call a method that is not available in the class.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Class Implementation:
  
  Go to the ABAP Workbench (transaction SE80) and locate the class mentioned in the error message.
  Verify that the class implements the interface specified in the error message. You can do this by checking the class definition and ensuring that it includes the interface in its declaration.
  
  
  
  Implement Missing Methods:
  
  If the class does not implement the required interface, you will need to add the necessary methods to the class. This may involve coding the methods as defined in the interface.
  
  
  
  Review Infotype Configuration:
  
  Check the configuration of the infotype that is causing the error. Ensure that it is correctly set up to use the appropriate class and interface.
  You can use transaction PE01 or PE02 to review and adjust infotype configurations.
  
  
  
  Transport Requests:
  
  If changes were made in a development environment, ensure that they are properly transported to the quality or production environment.
