  The SAP error message /IWPGW/CM_TGW_INBOX105 Enter a class which implements abstract class &1 typically occurs in the context of SAP Gateway development, particularly when dealing with OData services. This error indicates that a class that is expected to implement an abstract class has not been properly defined or is missing.
  Cause:
  
  Missing Implementation: The class that is supposed to implement the abstract class is either not created or not correctly defined.
  Incorrect Class Name: The class name provided does not match any existing class that implements the required abstract class.
  Configuration Issues: There may be issues in the configuration of the OData service or the service definition that leads to this error.
  Transport Issues: If the implementation was recently transported from another system, it may not have been transported correctly.
  
  Solution:
  
  
  Check Class Implementation:
  
  Ensure that the class you are trying to use actually implements the abstract class specified in the error message. You can do this by checking the class definition in the ABAP Workbench (transaction SE80 or SE24).
  
  
  
  Create or Adjust Class:
  
  If the class does not exist, you will need to create it and ensure it implements all the required methods of the abstract class.
  If the class exists but does not implement the required methods, you will need to adjust it accordingly.
  
  
  
  Verify Configuration:
  
  Check the OData service configuration in transaction /IWFND/MAINT_SERVICE to ensure that the service is correctly set up and that the correct class is assigned.
  Ensure that the service is activated and that there are no errors in the service definition.
  
  
  
  Check Transport Requests:
  
  If the class was recently transported, verify that the transport request was successful and that all necessary objects were included in the transport.
  
  
  
  Debugging:
  
  If you are still facing issues, consider debugging the OData service to trace where the error is occurring. This can provide more context on what is going wrong.
