• What is the cause and solution for SAP error message /IWFND/MED174 - Delta token is not supported for local services on the current system. ?

  The SAP error message /IWFND/MED174 Delta token is not supported for local services on the current system typically occurs in the context of OData services when using the SAP Gateway. This error indicates that the system does not support delta token functionality for local services.
  Cause:
  
  Local Services: The error arises when you are trying to use delta queries (which allow clients to retrieve only the changes made since the last request) on a local service. Local services are typically those that are not intended for external consumption and may not have the full capabilities of a standard OData service.
  System Configuration: The system may not be configured to support delta tokens for the specific service you are trying to access.
  Service Implementation: The OData service may not have been implemented to handle delta queries properly.
  
  Solution:
  
  Check Service Type: Ensure that the service you are trying to use is not a local service. If it is, consider using a different service that supports delta queries.
  Service Configuration: If you have control over the service implementation, check the service definition in the SAP Gateway Service Builder (transaction code SEGW) to ensure that it is set up to support delta queries.
  Use Standard Services: If possible, switch to using standard OData services that are designed to support delta functionality.
  Review Documentation: Consult the SAP documentation for the specific OData service you are using to understand its capabilities and limitations regarding delta queries.
  Contact SAP Support: If you believe that the service should support delta tokens and you are still encountering this error, consider reaching out to SAP support for further assistance.
