Demo: SQL Consumption of #BWonHANA Data and Models

Below, there is a 3 min screencam of a demo that shows how a BW infoprovider – in this case a composite provider – is exposed as a HANA view. The latter is then consumed via SQL from SAP Lumira. Thereby, BW security is also transferred to HANA. Furthermore, a change in the BW infoprovider – see step 12. – is automatically translated into the corresponding adjustment on the HANA end, meaning that the BW data model lifecycle is available for the generated HANA views too. Fig. 1 provides an overview of the benefits.

The demo script is the following:

  1. It starts in the new Eclipse-based editor for BW composite providers. A composite provider POS is picked.
  2. [0:16] By selecting the Overview tab the general settings for the composite provider become visible. The checkbox External SAP HANA View is checked.
  3. [0:23] Then the composite provider gets activated.
  4. [0:31] The perspective SAP HANA Modeler is selected in order to look into the HANA content catalog.
  5. [0:39] Under the default location Content → system-local → bw → bw2hana → Calculation Views a new view POS – same name as the related infoprovider – shows up.
  6. [0:45] POS is selected and its outline can be seen in the central panel.
  7. [0:52] Switch to Lumira; the latter is connected to the HANA instance underneath the BW-on-HANA system.
  8. [1:06] The generated view POS is selected.
  9. [1:20] In Lumira, a simple drill-down is executed on top of the generated HANA view.
  10. [1:35] We move back to the BW Modeling perspective in Eclipse.
  11. [1:42] Inside the composite provider editor, the Output tab is chosen.
  12. [1:45] An additional navigation attribute is activated for the characteristic Store and the composite provider is (re-)activated, thereby automatically (re-)generating the associated HANA view.
  13. [2:08] Switching to Lumira and reloading the HANA view definition (as it has changed).
  14. [2:30] A new attribute Country is now available …
  15. [2:35] … and used for a geographical drill-down using a map-based graphic.
