Writeback requests represent individual data transfer operations from CDF to an SAP system. Each request uses a configured endpoint and schema mapping to send data. You can create writeback requests and retrieve their status to monitor the data flow from CDF to SAP.

​
Overview

A writeback request is the unit of work that actually moves data from CDF to SAP. You create a request by providing the data payload, the endpoint to target, and the schema mapping to apply. CDF then sends the request to the SAP system and tracks its progress.

​
Request lifecycle

Each writeback request goes through a lifecycle:
  1. Created – The request is submitted and queued
  2. In progress – CDF is sending data to the SAP endpoint
  3. Completed – The SAP system accepted and processed the data
  4. Failed – An error occurred; you can inspect the error details and retry if applicable

​
Creating requests

When creating a writeback request, you specify:
  • Endpoint – Which SAP endpoint to use
  • Schema mapping – How to transform your CDF data for SAP
  • Payload – The actual data to send (typically from a CDF view or extracted data)
Poll the request status after creation to determine when the writeback completes and whether it succeeded. Failed requests include error codes and messages from the SAP system.

​
Error handling

If a writeback request fails, the response includes details about the failure. Common causes include connectivity issues, invalid mappings, or SAP validation errors. Fix the underlying issue and retry the request if appropriate.
