Hi Vivek,
As of SAP BW 7.30 SP08 powered by SAP HANA, the following mixed scenarios are available, however the consumption of SAP HANA data models was available in BW before SP8 and this can be done in two ways:
- TransientProvider based on HANA Model (no InfoObjects required)
- VirtualProvider based on HANA Model (BW managed metadata)
New scenarios in SP08 are:
- Direct loading of HANA data into BW based on new source system type: Operational Data Provider (ODP) with the context "HANA".
- Easy consumption of HANA master data in BW queries using BW Virtual Master Data.
- Flexible BW Data Provisioning for SAP HANA applications using Open Hub Destination with new target SAP HANA DB.
- Easy BW InfoProvider Consumption by generating Analytic View for BW InfoProvider via HANA Modeler.
In addition to the above, you can also implement a mixed scenario at the semantic layer in BI, or directly connecting Data Sources in tools such as Design Studio or Analysis to BW and HANA models.
In your described scenario where you have a HANA model (I'm assuming this a HANA Live VDM) in the ECC's HANA and you have a BW on HANA system, as far as I'm aware there is no way to generate a BW data model from a HANA model except using Transient or Virtual Providers to access HANA data in real-time. I believe this can be easily done across two HANA instances as well. You can also have a BW data model loaded from a HANA view using the new scenario described in first point above if staging or persist the data in BW is necessary.
Thanks,
MJ
