Extracting from S4/HANA to BW4/HANA

5258 Views

Hi All,

We have a S4 and a BW4 system in our landscape and I wanted to check on some of the best practices of data extraction. I have the below questions:

1. With the new BW4, we have 2 source systems ODP - SAP (Extractors) and ODP - ABAP CDS Views. The first one I assume is for the datasources and second one is to directly connect to a consumption view. Is this correct.

2. Are the new extractors based on ABAP CDS instead of function modules? I assume there are new ones that have ABAP CDS as their back end but the older ones still exist. Is this correct?

3. If I need to extract a CDS view to BW, should I use the ODP - ABAP CDS Views source system or rather put a datasource on top of it and then use the ODP - SAP (Extractors)? What's the best practice?

4. How do we manage deltas when extracting from CDS?

Thanks in advance.
