17.7 BW/4HANA Model Transfer
1. Why model transfer exists
SAP Datasphere supports importing existing SAP BW/4HANA models to reuse metadata and data in supported scenarios.
Current SAP documentation states that the Import Entities wizard can import supported BW/4HANA InfoProviders and analytic queries, with model-transfer capabilities depending on the source release.
2. What transfer means
Model transfer is not necessarily a database copy.
Think:
Existing BW model
|
metadata / supported model transfer
|
Datasphere
|
new semantic / consumption architecture
3. Validate supported release
Current documentation explicitly notes support boundaries for certain BW/4HANA import scenarios.
Never build a migration plan around an assumed universal import capability.
Check:
- BW/4HANA release,
- object type,
- transfer method,
- supported metadata,
- semantic behavior,
- unsupported features.
4. Query reuse
Analytic queries can be imported in supported scenarios.
This can accelerate modernization, but query import does not automatically produce an ideal enterprise semantic architecture.
Review:
- filters,
- variables,
- calculated measures,
- restricted measures,
- hierarchies,
- authorizations,
- consumer behavior.
5. Migration principle
Use transfer to reduce migration risk.
Do not use transfer as an excuse to preserve every historical design forever.
Exercise
Select one BW/4HANA CompositeProvider and one query.
Create a migration assessment:
- transferable metadata,
- unsupported behavior,
- target Datasphere model,
- consumer dependencies,
- validation plan.
