Getting structure in the new HANA environment is not as easy as it first seemed. It all started easy, just one model to combine some ADSO generated views and use it in Analysis for Office. But after these scenario’s some new requirements popped-up: the simple views needed an update and became more and more complex. Some logic from the ADSO was removed and put into HANA views, meaning that the previously used generated views had to be remapped. That got us thinking… We needed a more efficient way to avoid this in the future.
Every layer connects to the layer underneath with the use of a contract layer. This takes care of the mapping between two layers. A view in one layer does not care what happens in the other layer (and should NOT be used in another layer), the only thing they need to respect is “the contract” in between. A model can change to whatever is necessary as long as it respects the contract. In doing so everybody using the contract knows that anything being build on top of it will work after updates or changes down the line.
Objective: Reporting layer, exposed views for the reporting tools.
Objective: Contract between Analytic and Model.
Objective: Development layer: create / combine / apply company logic.
Objective: Decouple the data from the system.
Objective: Data from every source possible.
That is the deadline when you are running a BW version 7.4 or older. SAP will end the mainstream maintenance for older BW products and encourage companies to move to newer versions, preferably BW/4HANA. If you read this and find yourself in this situation, don’t panic. Politicians would say that it’s way past 5 before 12. Luckily, we are consultants and see a solution instead of a problem.Read more >
