Hi, everybody.
When HANA will be implemented in a company for business applications running in the ERP, the first concern is to decide about which will be the scenario.
- Side By Side: Is less disruptive because maybe it not requires an upgrade to SAP NetWeaver 7.4
- HANA as primary persistence for the SAP Business Suite: Requires a upgrade to SAP NetWeaver 7.4
Which is the impact that has selecting the side-by-side scenario compared to the primary persistence scenario?
I have seen that with the Side-by-Side scenario HANA artifacts are accessed from ABAP applications using ADBC, and therefore with this approach SAP HANA artifacts are not so integrated in the ABAP dictionary.
In the case of the primary persistence scenario the HANA artifacts are accessed creating new Dictionary objects (external views, database procedure proxy) through the Eclipse ADT plugin. Once this objects are created, developed SAP HANA artifacts are fully integrated to the ABAP dictionary, so ABAP code is more easy and readable.
On the other hand, I have seen that with SAP HANA, appears important enhancements for ALV and FPM named ALV and FPM with IDA (integrated data access), which consists mainly in skipping the Application server and so communicating the front-end directly with the SAP HANA database.
My questions is. Can we use ALV and FPM with IDA in a side-by-side scenario?
Thanks & Regards.
