Three distinct Deployment choices exist:
In this model, the client acquires both software and hardware, and the client itself administers the operations.
Cloud solution: Here, the cloud solution provider offers the software and hardware, which is then leased to the client.
Hybrid solutions: In this model, the client runs part of the software on their own on-premise server, and the client provider supplies an additional solution.
4. Could you explain what a modeling studio is?
Modeling studio specifies the tables that are preserved in HANA, the initial step is to obtain the meta-data and subsequently schedule data replication jobs. It manages Data Services to incorporate data from SAP Business Warehouse and other systems. It handles ERP instances connections, the current release doesn’t support connecting to multiple ERP instances. It uses data services for modeling, executes modeling in HANA itself, and essential licenses for SAP BO data services.
5. What are the merits of an in-memory platform?
In-memory databases allow processing of even the largest data volumes swiftly. This in itself is a major advantage over older technologies. Additionally, in-memory technology allows more opportunities in developing innovative applications that provide real business utility, including:
Integration of a range of data formats like text, images, videos, etc., through virtual access (without needing to import data into SAP HANA), real-time transfer, time-dependent integration, or data imports from Hadoop clusters. It also allows for application development directly on the platform without a separate application server and provides foundational functions for additional data processing, like displaying data on maps based on the SAP HANA geospatial engine.
6. What constitutes the main components of S/4HANA?
S/4HANA consists of three primary components.
HANA Platform or HANA Database: This in-memory HANA database runs SAP S/4HANA ERP systems. It addresses many issues encountered by ERP. S/4HANA (Business suite): This is an updated version of the SAP business suite 7 and includes built-in technologies like AI, machine learning, and analytics. Fiori UI: This modern user interface is integrated into SAP S/4HANA. It ensures a consistent look and feel across all devices and ERP systems, which aids in both employee satisfaction and productivity.
7. What are end-to-end business processes?

Data Virtualisation: SAP HANA improves data quality with built-in data quality capabilities, offers data federation, data replication, and integration capabilities. It serves as a real-time gateway to all your data across applications, cloud, and storage.
12. What is SAP BTP?
SAP BTP, also known as SAP Business Technology Platform, is a fundamental technological component that powers integrated suites and extensions. It’s divided into four main sections: Database and data management, Analytics, Application development and integration, and Intelligent technologies.
13. What happens to existing modifications when a customer moves to SAP S/4 HANA?
Note: this is just an over answer you don’t need to learn the whole thing just understanding it will be enough
When customers transition to SAP S/4HANA, they get a chance to assess their current modifications and streamline their solutions. It’s common for customers to discover that about half of the modifications, which previously hindered quick release cycles and necessitated lengthy testing, are no longer essential for their operations, having merely been remnants of past projects. Remaining modifications could be created in a less disruptive way.
In the transition to the public cloud edition of SAP S/4HANA, clients move their modifications to SAP HANA Cloud Platform in an extended format. Clients opting for the SAP S/4HANA managed cloud edition are advised to utilize SAP HANA Cloud Platform extensions for enhancement provisioning. Basic field extensions can be executed directly within the SAP Fiori UX, while the SAP HANA Cloud Platform can be used for more substantial developments.
The on-premise edition of SAP S/4HANA offers the most customization options: either on-premise as has been traditionally done, or through the SAP HANA Cloud Platform. SAP provides several examples of SAP Business Suite clients who use SAP HANA Cloud Platform extensions for on-premise systems. Generally, the SAP HANA extension framework within SAP HANA Cloud Platform utilizes SAP HANA as the shared platform for SAP S/4HANA, and offers further options like integrating open source solutions.
This extension framework has the benefit of separating modifications from the core, promoting agility in on-premise deployment and ensuring flexibility in cloud deployments. Instead of altering the core code, enhancements are placed in a “safe” environment, enabling innovation packages to be easily implemented. The core SAP S/4HANA system remains “clean” and can be swiftly and easily updated when new innovations are introduced – in a similar manner to how consumer mobile apps are regularly updated.
14. Mention what is the advantage of SLT replication?
SAP SLT uses a trigger-based approach that ensures no substantial impact on the source system’s performance. It provides data transformation and filtering capabilities and enables real-time data replication from SAP and non-SAP source systems into HANA. It is fully integrated with HANA studios and supports replication from multiple source systems to a single HANA system and vice versa.
15. How can I switch to SAP S/4HANA?
There are three main approaches to switch to SAP S/4HANA: a fresh installation or greenfield approach, a system conversion or brownfield approach, and landscape transformation.
16. What is the decision table in SAP HANA?
The decision table in SAP HANA is an instrumental tool in the decision-making process. It encapsulates business rules and logic in a simple, easy-to-use table format, enabling decision-making based on multiple conditions.
17. Name four intelligent technologies that improve SAP S/4HANA Cloud business processes.
We can list four technologies: Situation handling, Robotic process automation (RPA), Machine learning and predictive analytics, and the Internet of Things (IoT).
18. What are SAP HANA’s limitations?
SAP HANA is not ideal for handling and analyzing petabytes of unstructured data, typically known as big data. It’s not designed for social networking and social media data analytics. While SAP has pledged to develop more HANA-optimized applications, only a few are currently available, and HANA isn’t pre-optimized to support non-SAP applications, which would necessitate extensive application re-engineering.
19. Explain what happens if the replication is suspended for a longer period of time or system outage of SLT or HANA system?
If replication is paused for an extended period, the logging tables’ size increases.
20. What is OLTP?
OLTP, or Online Transaction Processing, is a type of software application that supports transaction-based programs. These systems are designed to handle a large volume of short online transactions in real time and are commonly used in industries with high transaction volumes, like banking, airlines, and retail.
21. Can we make changes to SAP Fiori apps?
Absolutely. SAP Fiori apps support both end-user personalization and key user customization. Business users can alter the layout and themes, and key users can adjust the UI to align with corporate standards and processes.
22. What is the fundamental difference between the old SAP business suite code line and the new SAP S/4HANA product code line?
SAP S/4HANA eliminates all artefacts that were performance workarounds in the classical row-based RDBMS. This includes aggregates and programmed indexes that had no semantic value and were there merely for faster data access. These have caused complications in the application and created complexity in managing system locking to avoid conflicting updates. Moreover, significant code had to be developed for ETL scenarios incurring data preparation and exception management routines caused by latency. With SAP S/4 HANA, these restrictions and workarounds are no longer necessary.
