1. What is SAP BW/4HANA and how does it work in C_BW4HANA_27?
SAP BW/4HANA is SAP’s latest and finest in-memory, HANA-native data warehousing solution that runs on SAP HANA exclusively. The naming convention follows that of their S/4HANA solution, which was released 18 months ago. This isn’t surprising, given that HANA is a critical component of SAP’s long-term innovation strategy.
2. What is SAP’s marketing strategy for SAP BW/4HANA?
- Simplicity: SAP’s BW product has introduce a plethora of options and capabilities over the years, leaving new customers perplexed as to which alternatives should be considered when commencing on a BW installation journey. SAP has decided to remove the unnecessary options and replace them with more relevant and easier-to-understand options for BW/4HANA setups. Customers “should” be exploiting BW/4HANA’s building pieces for the foreseeable future.
- One of SAP BW/4HANA’s most compelling features is its ability to distinguish the different types of data stored in each table. This allows it to determine which data must be kept in memory (hot) and which data can be put on drive automatically (warm). This type of automated intelligent data storage allows SAP customers to make better use of their hardware investment.
- Openness: To construct a data warehouse, pre-built, standardise templates known as “Building Blocks” are used. Customers will benefit greatly from the ability to offer BW/4HANA models and data as native HANA views that can be queried using regular SQL. Various visualisation tools can then ingest these views (i.e. BusinessObjects, Lumira, etc.).
- Modern User Interfaces: Let us all bid farewell to the SAP GUI. SAP has worked hard to improve its user experience across all of its product lines, and SAP customers are starting to reap the benefits. In SAP BW/4HANA, this trend continues. Visualization, storytelling, and data exploration are all made easier with BusinessObjects Cloud’s modern user interface. The digital boardroom can also access BW/4HANA. Finally, administrators should be please to learn that front ends can now be accessed via HANA Studio and modern browsers.
3. Which companies does SAP suggest leverage this new technology?
Nearly 17,000 BW customers haven’t yet made the switch to HANA, according to SAP. In addition, 3,700 clients have already switched to HANA from whatever database they were using previously. SAP has committed to making the transition to a new HANA-native data warehouse as simple as possible. Fairfax Media was one of the first companies to install BW/4HANA.
4. What are the options for SAP BW customers that want to upgrade?
The most cost-effective solution is to upgrade to SAP BW 7.5 SP4 on HANA. This speeds up the conversion to the new object types and the activation of “HANA-only mode,” which inhibits the creation of legacy objects. For most consumers, this will be a one-step process.
5. Is SAP BW/4HANA a cloud-based solution in C_BW4HANA_27?
It isn’t yet, but it will be soon. SAP is even considering a Rapid Deployment Solution for on-premise deployment (RDS). SAP chose to introduce SAP HANA Enterprise Cloud (HEC) and Amazon Web Services as a “cloud-first” solution (AWS). AWS is their first partner to be announce, but SAP is anticipated to reveal other partners soon after. As approved by SAP, AWS can manage a 14TB scale-out cluster running on seven of its X1 instances. Customers of BW/4HANA may now test, execute, and optimise massive workloads on AWS.
6. SAP BW/4HANA is a business warehousing application for the future generation. What distinguishes it from SAP Business Warehouse (SAP BW) 7.5?
Data structures, data flow, and data life-cycle management are all simplified with SAP BW/4HANA. It may access any non-SAP data in the firm because it is connected to SAP HANA and enterprise information management (EIM). It also includes the most up-to-date user interfaces (UI) for end-users, BW modellers, and administrators, as well as SAP HANA, a strong in-memory platform that provides great performance.
7. Why should businesses use SAP BW/4HANA? What are the advantages in C_BW4HANA_27?
Businesses use SAP BW/4HANA to improve their company agility. Because the warehouse structure has been greatly simplified and a new data flow modeller has been included, SAP BW/4HANA users may respond fast and simply to new model business needs as well as changes to existing models. Users can construct views automatically with SAP BW/4HANA objects, modify them with any SQL tool, and visualise the data with SAP BusinessObjects Cloud or SAP Lumira. This enables agile database development, providing businesses with superior real-time insights at a lesser cost.
There are several flexible deployment options available in SAP BW/4HANA, both in the cloud and on-premise. Customers may rapidly and easily set up their infrastructure in the cloud, and it offers excellent value for money. SAP BW/4HANA is presently available in the cloud via SAP HANA Enterprise Cloud, Amazon Web Services, and Microsoft Azure.
8. What part of SAP’s data warehousing strategy does SAP BW/4HANA play?
SAP continues to provide customers with a SAP, SQL-based, and business warehouse approach to data warehousing. Next, SAP BW/4HANA is a model- or application-driven approach to data modelling, data management, monitoring and scheduling, and ETL with fully integrated services. SAP BW/4HANA will become more interoperable with SQL-based data warehouses in the future.
9. Will customers be able to get support for previous SAP BW versions?
Although SAP BW on SAP HANA and SAP BW on traditional databases (xDB) will continue to be maintain, SAP BW/4HANA will be SAP’s primary revolutionary data warehouse solution. Customers who are planning to transition from SAP BW on xDB to SAP BW/4HANA should migrate their databases to SAP HANA and upgrade to SAP BW 7.5. We recommend upgrading to SAP BW 7.5 for clients wanting to migrate from SAP BW 7.3 or 7.4 to SAP BW/4HANA. As an interim phase, customers should integrate SAP BW 7.5 edition add-on for SAP HANA.
The edition add-on can be use to deploy tools for converting SAP BW objects to SAP HANA-optimized objects and data flows. Customizations can limit the level of automation that the tools can achieve otherwise. Customers can migrate to SAP BW/4HANA once all objects and data flows have been migrate and a first system check has been complete without errors.
10. Is it possible for clients to continue using SQL-based SAP HANA data warehousing?
Yes, the SQL technique will continue to be supported. Customers now have a choice in addition to SAP BW/4HANA. The optimum solution is determine by the customer’s priorities, level of expertise, and the model that determines their needs. There is no correct or incorrect response. Many customers discover that a hybrid strategy is the greatest fit for their requirements.
11. Will SAP BW/4HANA have the same features as SAP BW 7.5 on SAP HANA?
SAP BW/4HANA is identical to SAP BW powered by SAP HANA in terms of functionality. However, SAP BW/4HANA exclusively processes SAP HANA-optimized objects, reducing modelling work and SAP BW/4HANA’s overall complexity. According to the SAP S/4HANA road map, SAP BW/4HANA will be significantly different from SAP BW 7.5 powered by SAP HANA in six months. Other database platforms are not compatible with SAP BW/4HANA.
12. If customers have just upgraded to SAP BW 7.5, why should they transition to SAP BW/4HANA?
For SAP BW on SAP HANA users, the major advantages of SAP BW/4HANA are its simplicity, openness, enhanced UIs, and performance. As shown in the road map, we want to significantly improve the solution in the three releases that will follow in the next quarters.
13. What is the relationship between SAP BW/4HANA and SAP S/4HANA?
SAP BW/4HANA is not dependent on SAP S/4HANA in any way. Customers are not require to utilise one in order to use the other. SAP S/4HANA Analytics can be use to generate operational reports based on data directly from S/4HANA systems. SAP BW/4HANA, on the other hand, is a sophisticated data warehouse that can generate reports based on current, historical, and external data from a variety of SAP and non-SAP sources.
14. Is SAP BW/4HANA only available to SAP customers?
No, it may be use for any data warehousing need, including SAP and non-SAP data.
15. Can SAP BW/4HANA be utilized with certain analytics tools?
SAP BW/4HANA supports SAP BusinessObjects Cloud and SAP BusinessObjects BI. It also offers interfaces that can be use by third-party vendors.
16. What does it mean to partition a table?
Table partitioning is use to manage large amounts of data and increase application efficiency. 0CALMONTH and 0FISCPER make up the partition. There are two different types of partitioning that are use.
- Partitioning a database
- Partitioning logically
17. What is ODS (Operational Data Store) and how does it work?
For detailed data storage, the ‘Operational Data Store,’ or ‘ODS,’ is utilise. It’s a Business Warehouse architectural component that sits between PSA (Persistent Staging Area) and infocubes and allows for BEX (Business Explorer) reporting. It is not based on the star schema and is mostly use for detail reporting rather than dimensional analysis. Unlike infocubes, ODS (Operational Data Store) objects do not aggregate data. New records are inserted, current records are update, or old records are destroyed as define by the RECORDMODE value to load data into an IDS object.
18. What exactly is a “Infocube” in C_BW4HANA_27?
The star schema is use to structure ‘Infocube,’ which is a data storage space. You’ll need one ‘fact table’ surrounded by four dimensions to make an infocube. Different dim tables surround the ‘fact table,’ which are linked to DIM’ ids. In the cubes, you’ll have aggregated data based on the data.
19. Is SAP BW/4HANA only available to SAP customers?
No, it may be use for any data warehousing need, including SAP and non-SAP data.
20. Can SAP BW/4HANA be utilized with certain analytics tools?
SAP BusinessObjects Cloud and SAP BusinessObjects BI are both support by SAP BW/4HANA. It also offers interfaces that can be use by third-party vendors.
21. What is the architecture and components of the SAP BW system in C_BW4HANA_27?
- Processor for OLAP
- Repository of Metadata,
- Other functions include a process designer.
- Explorer of Business BEx is a business intelligence (BI) reporting and analysis application that supports query, analysis, and reporting operations. BEx allows you to perform many levels of analysis on historical and current data.
22. What data sources did you use to get data for the SAP BW system?
- SAP (SAP Applications/SAP ECC) systems
- Database with Relationships (Oracle, SQL Server, etc.)
- a file that is flat (Excel, Notepad)
- Source systems with multiple dimensions (Universe using UDI connector)
- Web services that use push technology to provide data to BI
23.Which component can you import data into when using SAP BI7.x?
You can load data from source systems into Persistence Staging Area and targets in BW 3.5, but data load in SAP BI 7.0 should be limited to PSA only for the current versions.
24. What is an InfoPackage, and how does it work in C_BW4HANA_27?
An InfoPackage specifies how and when data from various data sources is loaded into the BI system. An InfoPackage comprises all of the data loading information from a source system to a data source or PSA. A condition for requesting data from a source system is include in the InfoPackage. Note that while utilising an InfoPackage in BW 3.5, you can load data from a source system into the Persistence Staging Area as well as targets, however if you’re using SAP BI 7.0, data load should be limited to PSA only for the newest versions.
25. What is the Extended Star Schema, and how does it work? In an expanded star schema, which tables are inside and outside cube?
Fact tables are linked to Dimension tables in the Extended Star schema, and Dimension tables are linked to SID tables, which are linked to master data databases. Fact and Dimension tables are inside the cube in the Extended star schema, but SID tables are outside the cube. Dim Ids are generated based on SIDs when transactional data is loaded into Info cube, and these Dim Ids are used in fact tables.
26. What distinguishes Extended Star Schema from Star Schema in C_BW4HANA_27?
One fact table can connect to 16 dimensions tables in the Extended Star schema, and each dimension table can have up to 248 SID tables allocated to it. SID tables are also known as Characteristics, and each one can have master data tables such as ATTR, Text, and so on. Each Dimension in Star Schema is linked to a single Fact table. Each dimension has only one dimension and is not normalised any further. A dimension table is a collection of attributes use to examine data.
27. What is an InfoObject, and why is it utilise in SAP Business Intelligence?
In SAP BI, Info Objects are the smallest unit and are utilise in Info Providers, DSOs, Multi Providers, and so on. There are numerous Info Objects in each Info Provider. In reports, InfoObjects are used to analyse data and deliver information to decision makers.
28. What is the purpose of the Infoarea in SAP BW in C_BW4HANA_27?
In SAP BI, Info Areas are use to group objects of the same type together. Info Cubes and Info Objects are managed using Info Areas. Each Info Object is store in an Info Area, which you can use to create a folder for storing similar files.
29. In BI, how can you get access to source system data without having to extract it?
To gain direct access to data in a BI source system. Using Virtual Providers, you can get immediate access to source system data in BI without having to extract it. Virtual providers are define as InfoProviders that do not keep transactional data in the object. Only read access to BI data is allow with virtual providers.
30. What are the many sorts of virtual service providers in C_BW4HANA_27?
- VirtualProviders based on DTP
- Secondly, VirtualProviders with function modules
