  The SAP error message "REST_CORE_TEXTS003 Metadata & not valid" typically indicates that there is an issue with the metadata associated with a REST API call in SAP. This error can arise in various contexts, such as when working with SAP Gateway, OData services, or other RESTful services.
  Causes:
  
  Invalid Metadata: The metadata being referenced may not exist, or it may be incorrectly defined.
  Service Not Activated: The OData service or the relevant service in the SAP Gateway may not be activated.
  Authorization Issues: The user may not have the necessary authorizations to access the metadata.
  Incorrect URL: The URL used to access the service may be incorrect or malformed.
  Version Mismatch: There may be a mismatch between the client and server versions of the API or service.
  Data Model Changes: Changes in the underlying data model that are not reflected in the metadata.
  
  Solutions:
  
  
  Check Service Activation:
  
  Go to the SAP Gateway Service Builder (transaction code /IWFND/MAINT_SERVICE) and ensure that the relevant OData service is activated.
  
  
  
  Validate Metadata:
  
  Use the service's metadata URL (usually something like http://<host>:<port>/sap/opu/odata/sap/<service_name>/$metadata) to check if the metadata is accessible and valid.
  
  
  
  Review Authorizations:
  
  Ensure that the user has the necessary authorizations to access the service and its metadata.
  
  
  
  Correct URL:
  
  Double-check the URL being used for the API call to ensure it is correct and properly formatted.
  
  
  
  Check for Changes:
  
  If there have been recent changes to the data model or service, ensure that the metadata is updated accordingly.
  
  
  
  Clear Cache:
