Data mapping is a foundational aspect of system integration in SAP landscapes, especially when using SAP Business Connect to exchange data across SAP and non-SAP systems. It defines how data elements from a source system correspond to those in a target system. Efficient and accurate data mapping ensures data consistency, reduces errors, and supports seamless business processes.
SAP Business Connect supports multiple data mapping techniques, primarily graphical mapping and code-based mapping. Both approaches have their strengths and are used depending on the complexity, flexibility requirements, and maintainability considerations.
This article explores these two mapping techniques, their applications, and best practices in the context of SAP Business Connect.
SAP Business Connect typically handles integration scenarios involving IDocs, BAPIs, RFCs, and web services, where the format and structure of data often differ between sender and receiver. Data mapping bridges these differences by:
Graphical mapping is a visual approach where users create mappings between source and target fields using drag-and-drop interfaces. SAP provides graphical mapping tools in platforms like SAP Process Integration (PI)/Process Orchestration (PO) and SAP Cloud Integration (CPI), which are frequently integrated with SAP Business Connect for advanced scenarios.
Code-based mapping involves writing scripts or programs that perform data transformations. In SAP ecosystems, common languages used are:
| Scenario | Recommended Mapping Technique |
|---|---|
| Simple or moderate data transformations | Graphical Mapping |
| Complex business rules or calculations | Code-based Mapping |
| Rapid prototyping or frequent changes | Graphical Mapping |
| High-performance and optimized flows | Code-based Mapping |
| Integration involving XML-to-XML transformations | XSLT (Code-based) |
Data mapping is a critical step in ensuring seamless and accurate data integration in SAP Business Connect environments. Both graphical and code-based mapping techniques offer valuable tools, with graphical mapping providing ease of use and rapid development, while code-based mapping offers unmatched flexibility and power for complex scenarios. By understanding the strengths and limitations of each approach, SAP professionals can select the right technique to build resilient and maintainable integration flows.
