Schema mappings define how CDF data is transformed and mapped to SAP data structures during writeback operations. Each mapping specifies the field-level correspondence between CDF resources and SAP function module parameters. You configure mappings to control exactly how data flows from CDF back to SAP.

​
Overview

When you send data from CDF to SAP, the schema mapping translates CDF field names and types into the structure expected by the target SAP function module or BAPI. Without a mapping, the SAP system would not receive data in the correct format.

​
Mapping structure

Each schema mapping defines:
  • Source – The CDF resource or view that provides the data
  • Target – The SAP function module parameters or BAPI structure
  • Field mappings – Which CDF fields map to which SAP parameters, including any transformations

​
Data transformations

Mappings can include simple field-to-field mappings or transformations. Common transformations include type conversions, string formatting, and applying default values when source fields are empty.
SAP function modules expect parameters in a specific order. Ensure your mapping aligns with the target function’s signature.

​
Managing mappings

You create schema mappings by specifying the endpoint and the field-level mapping configuration. You can update mappings to adjust the data flow without changing the endpoint or SAP instance setup.
