SAP DWC and SAC are cloud based embedded offerings coupled together on a single tenant provided by SAP for both Data Modelling and Reporting purpose respectively. In an hybrid structure the combination of both results a very tightly coupled and highly efficient reporting architecture. SAP DWC uses Smart Data Integration (SDI) and Smart Data Access (SDA) technologies to bring data from both SAP and Non-SAP source systems. Full-fledge Data modelling is still one of the challenges in SAC and that is why we have DWC in place to overcome this. In SAC it is possible to blend the data from multiple views but can create performance issues if data from the source is too huge. In a new modelling approach SAP is recommending to push all the business logic to the backend data modelling tool.
All the modelling actions can be easily performed in SAP DWC which is cloud based tool that allows both GUI and SQL based modelling and provides easy connection with both SAP and non-SAP source systems. The complexity of integrating multiple systems in one tool is resolved by introducing DWC.
From the navigation point of view you can access SAC tenant through DWC homepage by clicking the Product Switch button at the top right of DWC screen. Click on Analytics to switch to SAC on this tenant.
But, it is also possible to expose the SAP DWC data models across the different tenants. This means SAP DWC data models can be linked to another SAC client running on a different tenant.
As shown below we have 2 Tenants and we will setup a Live connection from Tenant 1 to Tenant 2. DWC is currently present in Tenant 1 and we want to Live connect SAC on Tenant 2.
To achieve this please follow below shown configurations in the Target SAC tenant and complete few prerequisites in DWC.
One of the prerequisite in DWC is that the data model from DWC needs to be deployed of type Analytical Data Set else it won't be visible in above screenshot. Navigate to the Data tab in SAC to find the dimensions and measures to be visible from the DWC data model.
Conclusion: We have now successfully setup a live connection between two Tenants - Tenant 1 and Tenant 2 and we connected SAP DWC running on Tenant 1 with SAC on Tenant 2 through a Live connection. This feature provides a lot of flexibility to our end users across multiple regions and to access the data based on their roles and authorizations.
