Hello @yaswanth31102000 

The error occurs because Integration Suite can’t fetch $metadata with the credentials or adapter you’re using. Key points.

• Use a Communication User from a Communication Arrangement (S/4 Public Cloud) or an OAuth client (ABAP Cloud/Steampunk). Your email login as a dialogue user will not work.
• Ensure your RAP service is published in the Service Binding and that you copy the exact Service URL from it there.
• Check that the adapter matches the binding:
  • RAP OData V2 → use OData V2 adapter with Basic Auth (Comm. User).
  • RAP OData V4 → use OData V4 adapter or HTTP adapter; V2 wizard won’t load V4 metadata.
• Ensure you can open <service-URL>/$metadata in a browser using the communication user before setting up Integration Suite.

That should resolve the metadata load error.
