Introduction
This blog is an extension of my colleague Jeetandra Kapase's informative blog on How to create SAP Datasphere service instance in the SAP BTP Platform as customers have had questions on the next steps on adding the BW Bridge or the embedded Data Lake.
By the end of doing the steps in Jeetandra’s blog, a Datasphere service instance will be created and the System Owner will receive an activation email with instructions on how to access the tenant. They will then have the authorizations to perform the next configuration steps.
Some customers may also want to include SAP BW Bridge and/or the HANA Cloud Data Lake offering in their new Datasphere tenant created from SAP BTP Platform. This blog will link you to resources to size the required components and how to access the tenant configuration.
Please note that BW Bridge and Data Lake are not available as part of the free tier option in BTP. See SAP Note 3227267.
There may also be some limitations on using the Flexible Tenant Configuration based on the region you are in. See SAP Note 3144215.
For any questions you may have about BW Bridge and the Embedded Data Lake through BTP as far as your use cases, costs etc. , please contact your SAP Account team.
What is SAP Datasphere BW Bridge and who would benefit from it?
SAP Datasphere, BW Bridge is a function enhancement of SAP Datasphere. Organizations that may consider using the BW Bridge include those that:
- Already have investments in SAP BW and BW/4HANA and want to leverage the benefits of cloud-based data warehousing by either migrating or extending their current investments with SAP BW and BW/4HANA.
- Seek to integrate SAP BW and BW/4HANA with other SAP Datasphere capabilities and artifacts.
- Are looking for a scalable, flexible, and cost-effective solution for data warehousing and analytics.
The BW Bridge supports ABAP ODP Data Sources. It also utilizes the familiar BW Tooling (Eclipse, SAP HANA Studio etc.) so experienced BW users can start using BW Bridge without much of a learning curve. Objects in the BW Bridge can then be shared with other Datasphere Core Artifacts for further integration with other system data to create Analytic Models and other uses.
For more information on the BW Bridge and its use case, please see the following blog for a BW Bridge technical deep dive
Architecture of BW Bridge
What is SAP Datasphere's Embedded HANA Cloud Data Lake?
The Data Lake in SAP Datasphere is an essential component designed to store and process large volumes of raw and unstructured data leveraging inexpensive storage options to lower costs. This is generally data that does not frequently change. SAP Datasphere has the option to include an embedded Data Lake in its environment and access the data to integrate with other SAP Datasphere artifacts. For more information, please see the following blog Working with the embedded data lake in Datasphere
Some customers may already have a standalone HANA Cloud with Data Lake. In this case, they do not need to add the Datasphere embedded Data Lake as they can also interact with a Stand Alone Hana Cloud environment and its Data Lake by creating Connections in Datasphere.
Sizing Resources
To view all supported size combinations, go to the SAP Datasphere Capacity Unit Estimator.
Before allocating resources to BW Bridge, it helps to understand the sizing required for your company. Refer to the blog Get ready for SAP BW Bridge SAP Datasphere Cloud Sizing Report
For the Data Lake, You can specify from 0 TB (minimum) to 90 TB (maximum), by increments of 5 TB.
When adding additional components in the Tenant Configuration, it is advised to talk to your SAP Account Team for any guidance if there are any doubts as once the sizing is set on the tenant, currenty it can't be downsized without SAP's support. See SAP Note 3144215
Steps to assign resources for BW Bridge and Data Lake
Once the System User has access to the Datasphere tenant, navigate to the Flexible Tenant Configuration (FTC) first introduced last year to configure the size of the tenant. In the Datasphere tenant, using the top Left menu, navigate to System -> Configuration and then select the Tenant Configuration tab.
See the official documentation: Configure the Size of Your SAP Datasphere Tenant.
Flexible Configuration Tool
As soon as you Save, the SAP Datasphere instance will be create the assets and the allocated capacity units are assigned. Creation could take up to 90 minutes or so.
Where to find Next Steps Documentation
Once the Tenant Configuration is saved and complete:
For SAP BW Bridge, as a system owner, continue with the next configuration steps using the Official BW Bridge Documentation.
For the Data Lake, when creating or editing a space, you will have to assign one of the spaces to the Data Lake. See the Official Help Documentation for Data Lake.
Hope this blog helps in understanding the followup steps to add components for SAP Datasphere created from BTP.
