17.4 BW Bridge Data Acquisition
1. Acquisition architecture
BW bridge can use SAP BW-oriented acquisition capabilities, including supported extractors and SAP application integration.
A simplified pattern is:
S/4HANA / SAP Business Suite
|
extraction
|
BW bridge
|
persistence
|
processing
2. Why acquisition remains important
Migration projects often focus on target models and underestimate source extraction.
But extraction defines:
- available fields,
- delta behavior,
- source workload,
- data completeness,
- recovery behavior.
3. SAP business content
SAP documents BW bridge support for connectivity and business content for SAP Business Suite and S/4HANA.
This can reduce custom extraction development where supported content fits the requirement.
4. Acquisition design checklist
Validate:
- source release,
- extractor or source object,
- delta capability,
- initial-load method,
- authorization,
- source workload,
- data volume,
- deletion semantics,
- monitoring,
- recovery.
5. BW bridge versus native Datasphere acquisition
Do not automatically route every SAP source through BW bridge.
Compare:
| Requirement | BW bridge | Native Datasphere |
|---|---|---|
| Existing BW extraction investment | Strong fit | May require redesign |
| BW transformation semantics | Strong fit | Redesign |
| New cloud-native model | Evaluate | Often simpler |
| SAP extractor reuse | Strong fit where supported | Depends on supported connection |
| Minimal BW dependency | Weaker | Stronger |
Exercise
For an S/4HANA Finance source, compare:
- BW bridge extractor,
- extraction-enabled CDS,
- native Datasphere replication.
Select one for a daily enterprise finance mart and one for near-real-time operational analytics.
