Ques:
There are some requirements within your organization where you have to pull the data from External DB using the Real-Time Data Acquisition (RDA) Process.
This kind of data needs to be available for Real-Time Data Reporting.
How you are going to configure it?
What could be the prerequisites you have to take care of?
Are there any challenges that will be there?
ANS
The process of pulling the data from an external database into SAP BW HANA using Real-Time Data Acquisition (RDA) requires a lot of careful configurations. Here is how we can go ahead with the approach of configuring the RDA for this scenario:
Configuration of RDA in SAP BW HANA:
Set up RDA Process – We can use real-time data acquisition to pull the data from the external system in real-time for immediate use in reporting. This process is typically used to extract transactional or other time-sensitive data from external systems directly into SAP BW.
General steps for RDA Configuration:
– Configuration of the Source System by defining it, in SAP BW.
– Using ODP or DB Connect to establish the connection between SAP BW and external DB.
– For Non SAP Sources, it is needed to configure the RFC connection or ODP-based adapters to fetch the data from external systems in real-time.
– DTP Configuration: This is to load the data from the source system to SAP BW. The DTP Type should be set to real-time for continuous data flow. Set up the delta extraction for real-time data replication, to make the data available immediately.
– Create Real-Time ADSO to hold the real-time data coming from the external database. This real-time ADSO is optimized for quick access and ready for reporting.
– Once the real-time data is coming in BW, we configure the same query layer for real-time reporting. This way reporting layer setup is done.
This way we can configure the Real-Time Data Flow to ensure that data is transferred automatically from the external database into SAP BW HANA on an ongoing basis without manual intervention.
Key Considerations and Best Practices
- Real-Time Data Volume: Real-time data acquisition can lead to large volumes of data being processed at once. Make sure that your HANA system can scale horizontally and vertically to accommodate the growing data volume.
- Data Cleansing and Transformation: Consider using real-time transformation logic during the extraction process to clean and transform the data before it is loaded into the InfoProvider.
- Data Security: Ensure that sensitive real-time data is encrypted and adheres to compliance requirements.
- Integration Testing: Perform rigorous testing of the RDA configuration to ensure that real-time extraction is accurate and doesn’t overload the systems involved.
Conclusion:
To configure Real-Time Data Acquisition (RDA) for pulling data from an external database in SAP BW HANA, you will need to set up a seamless connection between the SAP BW system and the external system, configure real-time data flows via DTP, and ensure the real-time InfoProviders are optimized for performance. While there are significant challenges (data latency, system performance, etc.), they can be mitigated with the right configurations, monitoring, and data management strategies. With proper setup, you can achieve efficient real-time reporting while maintaining data integrity and performance.
