  The SAP error message CL_SADL_GW_MDE_MSGX050 typically relates to issues with the SAP Gateway and the Model Driven Entity (MDE) framework, particularly when there are problems with the data model or the service definition in the context of OData services.
  Cause:
  
  Missing or Incomplete Metadata: The error often indicates that the metadata for the OData service is either missing or not properly defined. This can happen if the service is not activated or if there are issues with the underlying data model.
  Service Activation Issues: The OData service may not be activated in the SAP Gateway, leading to the inability to access the required data.
  Authorization Issues: There may be authorization problems preventing access to the data or service.
  Incorrect Configuration: Misconfiguration in the service definition or the underlying data model can also lead to this error.
  
  Solution:
  
  
  Check Service Activation:
  
  Go to the SAP Gateway Service Builder (transaction code /IWFND/MAINT_SERVICE) and ensure that the relevant OData service is activated.

  Ensure that the user has the necessary authorizations to access the OData service and the underlying data.
  Use transaction SU53 to analyze any authorization issues after attempting to access the service.
  
  
  
  Debugging:
