Browse the Book This chapter covers the architecture of SAP HANA, describes the scope and deployment options of SAP S/4HANA, and discusses the basic fun ctions of the SAP Fiori user interface. These topics on SAP HANA and SAP S/4HANA make up 10% of the Financial Accounting Associates exam. The chapter includes real-world scenarios as well as practice questions to help readers test their knowledge.

Real-World Scenario As a consultant, you need to understand the underlying architecture that the SAP S/4HANA system is built on. SAP HANA is at the core of the SAP strategy, and you need to feel comfortable explaining this technology to your custom- ers in simple terms. SAP HANA is a faster database, but there’s more informa- tion you should be able to pass on without scaring nontechnical people off. SAP HANA is often perceived as expensive, so understanding technologies such as compression and columnar store on a high level can help you build a case to alter this perception for your potential customers. The SAP S/4HANA system is a separate product line from the old SAP ERP sys- tem. SAP ERP is no longer the default go-to enterprise resource planning (ERP) platform for SAP. This was a huge change and a business decision with quite a large risk for SAP. It has proven to be successful, and more and more customers are persuaded by the true benefits of the new system. But what’s special about it? How difficult is it to adopt? How can customers move to SAP S/4HANA, and do they risk losing the (potentially) millions they have invested in the “old” software? You need to be able to explain the reasons for this move by SAP and what it means for new and existing SAP customers. Finally, SAP Fiori is the default graphical user interface (GUI) for end users in SAP S/4HANA, so you need to be able to use it with confidence, explain its components, and describe the benefits it brings. Explain the importance of a simple interface with great usability and applications that can be used on mobile device and on desktops. You should also have knowledge of how the tile groups, tile catalogs, roles, and users cooperate to form what the user sees on his own SAP Fiori launchpad. 1.1 Objectives of This Portion of the Test The purpose of this portion of the certification exam is to test your general knowl- edge of the SAP HANA, SAP S/4HANA, and SAP Fiori applications. The certification exam expects you to have a good understanding of the following topics: Overview of SAP HANA in-memory architecture SAP S/4HANA products, and architecture for financials Deployment options for SAP S/4HANA SAP Fiori launchpad features SAP Fiori app types Intelligent Enterprise Framework Section 1.3 47 Note The SAP HANA and SAP S/4HANA topic makes up 10% of the total exam. 1.2 Digital Transformation Because the technological world is expanding with unprecedented speed, it’s imperative for businesses to not only catch up with these advances but also use them to their competitive advantage. Computers and software are traditionally considered supportive to business, and digital transformation brings the digital world to the forefront of innovation and makes it a key business driver on its own. Digital transformation in business implies the adoption and use of technologies such as big data, the Internet of Things (IoT), mobile, artificial intelligence (AI), and social media to drive business innovation and growth. 1.3 Intelligent Enterprise Framework The effect of digital transformation can be felt across business functions such as marketing, operations, human resources, administration, and so on. It forces orga- nizations and people to rethink and optimize how they execute business pro- cesses and how they can benefit from adopting automation in their day-to-day activities. SAP is investing heavily to support all facets of the digital enterprise and has adopted a strategic framework to help businesses run while using progressive enterprise technology. The SAP strategy for supporting the intelligent enterprise is focused on three key product offerings: Intelligent suite The intelligent suite includes all the SAP applications that support the end-to- end business processes of the enterprise (Figure 1.1). Figure 1.1 Intelligent Suite Digital platform The digital platform refers to SAP Business Technology Platform, an open busi- ness platform for building and delivering business applications. The strategy Digital supply chain Digital manufacturing Customer experience Spend management Financial management People management SAP S/4HANA Intelligent suite Chapter 1 Overview and Deployment of SAP S/4HANA 48 put forward by SAP is to shift development focus from the core solutions into the SAP Business Technology Platform to ensure the greatest flexibility both for SAP and third-party developers while maintaining a lean and stable core. Intelligent technologies The third and final component (formerly referred to under the SAP Leonardo product umbrella) is a technology framework that combines multiple modern technological tools that can be used to improve applications by providing auto- mation, detection, and prevention capabilities, among others. Some of the key words include process automation, AI, machine learning, blockchain, data intel- ligence, big data, IoT, and predictive analytics. Traditional business applications and ERP software packages aren’t designed to fully support businesses throughout this digital transformation journey. SAP saw this growing gap as an opportunity more than 10 years ago and created SAP HANA to be the core building block of business software that not only supports but also drives digital transformation. Today, SAP HANA is at the core of virtually all SAP product development. But what is SAP HANA, and why is it so important? 1.3.1 SAP HANA Architecture In its simplest form, SAP HANA is a database management system. It performs all the expected database functions of storing and retrieving data for applications that sit on top of it, but SAP HANA is unique in how it performs these tasks. In addi- tion, SAP HANA has embedded advanced analytics capabilities such as predictive analytics and text analysis, mining, and search. SAP HANA also offers application development services supporting a variety of programming languages. Finally, SAP HANA provides a slew of data access, administration, and security support ser- vices. Clearly, SAP HANA is much more than “just” a really fast database. Interesting as all the features are, we’ll concentrate on the database architecture. We won’t get too technical, and we’ll keep things in scope both for the certification and the financial accounting associate role. The SAP HANA database has three standout features that work together and make it unique: In-memory database Using RAM to store all data has only even been imagined as a possibility in the past decade or so. Memory is faster than disk storage—in fact, much faster. In best-case-scenario sequential reads, the best solid-state disks today can read data at about 3 GB/s. Modern, fast memory reads, writes, and copies at rates around 60 GB/s. That’s a factor of 20 against best-case-scenario disk drive speed. Of course, this method is more expensive, but these costs usually aren’t prohibitive for enterprises. In addition, the data storage capacities supported aren’t as large, but modern servers can support tens of terabytes of capacity. The memory size limitations aren’t critical in any but the most extreme cases due to the other features of SAP HANA, described in the next list items. Intelligent Enterprise Framework Section 1.3 49 Aggressive compression All major databases support compression, but what you save in space, you lose in speed. SAP HANA uses smart techniques to make compression a viable option while sacrificing little speed. You can expect data in an SAP HANA data- base to be compressed by a factor of 10 on average, meaning neither acquisition cost nor storage capacity is a huge factor. One of the ways SAP HANA avoids los- ing speed is by inserting only new data rather than editing existing entries; decompressing and recompressing for changing entries is a costly proposition. By only adding entries and appending the old ones, SAP HANA doesn’t go through the compress/decompress cycle. With versioning, the system knows always to uploads/Industriel/ certification-guide.pdf
