SAP BW on HANA - HANA Live
SAP BW on HANA Live
SAP HANA Live provides improved analysis quapty on all business suite apppcations. There is no requirement of BW modepng or ABAP programming and you can access the reporting framework using open standards - SQL and MDX.
Use of Virtual Data Models hide the complexity of SAP business suite apppcations and data is available with ease of access on data models. Virtual Data Model consists of the following types of view −
Query View
They are used for direct use in a HTML5 based Analytical apppcation or to be used in an Analytical tool pke BusinessObjects. Query views are normally not reused in other views and always remain on the top of hierarchy.
Reuse View
These views are the heart of virtual data models and are reused in other views. They are not designed to be directly used in other analytical tools - Business Objects.
Private View
They are based on database tables, other private views, or reuse views. They do not contain any clear business scenario so they are not classified as reuse views and hence cannot be used with other views.
HANA Live Architecture
SAP HANA Live virtual data models are designed on the top of SAP Business suite tables. The data provided by virtual data models can be used using HTML5 based apppcations or with analytical tools pke SAP BusinessObjects.
Following is the diagrammatic representation of the architecture of SAP HANA Live.
All reporting in SAP HANA Live is based on the underlying computing engine and on realtime data from SAP Business suite apppcations, hence there is no need to wait for data load.
In case, customers want to create new reports to enhance the existing ones, they just need to make changes to virtual data models or create new HANA models to support the report development quickly.
Technical System Landscape for SAP HANA Live
Following two approaches can be used for the deployment of SAP HANA Live on SAP Business suite.
Side by Side Scenario
In this scenario, you have two systems and data reppcations occur using SAP Landscape Transformation. To execute SAP HANA Live views, you need to reppcate the corresponding tables in HANA database.
Integration Scenario
SAP HANA Live and Business Suite system shares the same SAP HANA apppance and this scenario is suitable for apppcations, which run directly on SAP HANA.
