  The SAP error message /IWFND/CM_DATA_CON_S002 indicates that there is a mismatch between the version IDs of the consumer and the provider in an OData service. This typically occurs in scenarios where the consumer (the application or service making the request) and the provider (the OData service) are not aligned in terms of the version of the service they are using.
  Cause:
  
  Version Mismatch: The consumer is trying to access a version of the OData service that is different from the one that the provider is currently serving. This can happen if the service has been updated or if the consumer is using an outdated version.
  Service Configuration: The OData service might have multiple versions deployed, and the consumer is not configured to use the correct version.
  Caching Issues: Sometimes, caching mechanisms can lead to the consumer using an outdated version of the service.
  
  Solution:
  
  Check Service Versions: Verify the versions of the OData service that are available on the provider side. Ensure that the consumer is configured to use the correct version.
  Update Consumer Configuration: If the consumer is using an outdated version, update its configuration to point to the correct version of the OData service.
  Clear Cache: If caching is involved, clear the cache on both the consumer and provider sides to ensure that the latest version of the service is being used.
  Test with Postman or Similar Tool: Use tools like Postman to manually test the OData service and confirm that the correct version is being accessed.
  Check Service Metadata: Access the service metadata (usually available at the URL .../$metadata) to see the available versions and ensure that the consumer is aligned with one of them.
  
  Related Information:
