  The SAP error message /UI5/MP_CP_APP003 Annotation &1 not maintained in settings of OData datasource &2 typically indicates that a required annotation for a specific OData service is missing in the configuration settings of that OData data source. This error is often encountered when working with SAP Fiori applications that rely on OData services for data retrieval and manipulation.
  Cause:
  
  Missing Annotations: The specific annotation mentioned in the error message is not defined in the OData service metadata or is not properly configured in the settings of the OData data source.
  Incorrect Configuration: The OData service might not be correctly set up in the SAP Gateway or the relevant settings in the SAP Fiori Launchpad or application configuration might be incomplete.
  Version Mismatch: There could be a mismatch between the expected version of the OData service and the actual version being used.
  
  Solution:
  
  
  Check OData Service Metadata:
  
  Access the OData service metadata (usually available at the URL http://<host>:<port>/sap/opu/odata/sap/<service_name>/$metadata) and verify if the required annotation is defined.
  If the annotation is missing, you may need to update the OData service implementation to include the necessary annotations.
  
  
  
  Maintain Annotations in Settings:
  
  Go to the SAP Gateway Service Builder (transaction code SEGW) and check the service definition for the required annotations.
  Ensure that the annotations are properly maintained in the service settings.
  
  
  
  Update Service:
  
  If you have made changes to the OData service, ensure that you have activated the service and generated the runtime artifacts.
  Use transaction IWFND/MAINT_SERVICE to check if the service is active and properly registered.
  
  
  
  Check Fiori Launchpad Configuration:
  
  If the error occurs in a Fiori application, check the configuration in the Fiori Launchpad Designer to ensure that the OData service is correctly referenced and that all required annotations are included.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific Fiori application or OData service to understand the required annotations and their configurations.
  
  
  
  Debugging:
