A. Use "Developer Extensibility for data-intensive ABAP extensions to S/4HANA./Use "Side-by-Side Extensibility on SAP BTP ABAP Environment" when additional SAP BTP services are intensively used and SAPUI5 user interfaces are required.

Answer DescriptionExplanation:

The decision for the extension model in S/4HANA should be based on the nature of the extension required. Developer Extensibility (in-app extensibility) is suitable for data-intensive extensions that need to operate within the context of S/4HANA. This is because it allows for direct access to S/4HANA's digital core and leverages the power of the HANA database. It is the recommended approach when the extension requires tight integration with core data and processes, ensuring high performance and data consistency.

On the other hand, Side-by-Side Extensibility on SAP BTP ABAP Environment is recommended when the extensions need to utilize additional SAP BTP services such as advanced analytics, machine learning, IoT services, or when creating new user experiences with SAPUI5. This decouples the extensions from the S/4HANA core, which can be beneficial in terms of flexibility, agility, and reducing the impact on the core system during upgrades.

References= These practices are supported by SAP's extensibility guide for S/4HANA, which explains the two extensibility models and their appropriate use cases. SAP documentation on ABAP Platform extensibility options provides further insights into when to choose each extensibility approach. SAP Best Practices for Extensibility in SAP S/4HANA guide provides a comprehensive view on how to extend the digital core effectively while maintaining system integrity and upgradeability.

B. I use the SAP Discovery Center to check which of the selected SAP BTP services are offered by which hyperscaler. With help from the SAP Trust Center, I check in which data center the involved SAP SaaS solutions are available.

Answer DescriptionExplanation:

According to the SAP Discovery Center 1 and the SAP Trust Center 2, the steps involved in this validation are:

Use the SAP Discovery Center to check which of the selected SAP BTP services are offered by which hyperscaler. The SAP Discovery Center is a platform that provides access to SAP BTP services, events, and related resources, and helps you to implement your use cases on SAP BTP with step-by-step guidance and support from topic experts and SAP Community. In the Service Catalog section of the SAP Discovery Center, you can browse and filter the available SAP BTP services by category, region, or hyperscaler. You can also compare the features and pricing of different services, and learn how to use them in your projects.

Use the SAP Trust Center to check in which data center the involved SAP SaaS solutions are available. The SAP Trust Center is a platform that provides information on cloud performance, security, privacy, and compliance. In the Certification and Compliance section of the SAP Trust Center, you can find certificates, reports, and attestations that show how SAP meets various industry standards and regulatory requirements. You can also filter the documents by solution, region, or hyperscaler, and download them for your reference.

The other options (A and C) are not correct for how to validate the availability of SAP BTP services and SAP SaaS solutions in the desired hyperscaler’s data center, because they either do not exist or do not provide the required information. For example:

Option A is not correct because there is no such platform as SAP Business Accelerator Hub (api.sap.com) that provides all the required information regarding SAP BTP service and SAP SaaS solution availability for each hyperscaler. The correct name of the platform is SAP API Business Hub (api.sap.com), which is a platform that provides access to SAP APIs, events, and related resources, but it does not provide any information on the availability of SAP BTP services or SAP SaaS solutions for each hyperscaler or data center.

Option C is not correct because the SAP Discovery Center does not provide any information on the availability of SAP SaaS solutions for each hyperscaler or data center. The SAP Discovery Center only provides information on the availability of SAP BTP services for each hyperscaler or region, but not for specific data centers. To check the availability of SAP SaaS solutions for each data center, you need to use the SAP Trust Center instead.

A. To follow the clean-core strategy, the so-called "Developer Extensibility" of S/4HANA isn't allowed. Extensions must use "Side-by-Side Extensibility" on the SAP Business Technology Platform. These extensions use corresponding public remote APIs of the S/4HANA backend system.

C. 1. Assess and define the value propositions for the small size farms customer segment. /2. Detail the customer relationships and channels. /3. Identify relevant key activities, key resources, and partners. /4. Define the revenue streams and cost structure. /5. Define the eco-social benefits and costs.

Answer DescriptionExplanation: According to the Sustainable Business Model Canvas, which is a tool that helps entrepreneurs to design and communicate their business models in a sustainable way, the recommended sequence of steps is:
Assess and define the value propositions for the small size farms customer segment. This step involves defining and describing the products or services that Green Elk & Company offers to its target customers, and how they create value for them. The value propositions should address the needs, problems, or desires of the customers, and highlight the benefits or advantages of Green Elk & Company’s solutions over the alternatives.
Detail the customer relationships and channels. This step involves defining and describing how Green Elk & Company interacts with its customers, and how it reaches and delivers its products or services to them. The customer relationships should reflect the type and level of engagement that Green Elk & Company wants to establish and maintain with its customers, such as self-service, personal assistance, or community. The channels should reflect the most effective and efficient ways to communicate and distribute Green Elk & Company’s value propositions to its customers, such as online platforms, physical stores, or partners.
Identify relevant key activities, key resources, and partners. This step involves identifying and describing the main activities, resources, and partners that Green Elk & Company needs to perform and leverage to create and deliver its value propositions to its customers. The key activities should reflect the most important tasks or processes that Green Elk & Company undertakes to execute its business model, such as production, marketing, or sales. The key resources should reflect the most essential assets or inputs that Green Elk & Company requires to execute its business model, such as human, physical, financial, or intellectual resources. The key partners should reflect the most strategic relationships or collaborations that Green Elk & Company establishes with other entities to execute its business model, such as suppliers, distributors, or competitors.
Define the revenue streams and cost structure. This step involves defining and describing how Green Elk & Company generates income from its customers, and how much it spends to execute its business model. The revenue streams should reflect the sources and mechanisms of income that Green Elk & Company obtains from selling its products or services to its customers, such as sales, subscriptions, or fees. The cost structure should reflect the types and amounts of expenses that Green Elk & Company incurs to execute its business model, such as fixed costs, variable costs, or economies of scale.
Define the eco-social benefits and costs. This step involves defining and describing how Green Elk & Company contributes to or affects the environment and society through its business model. The eco-social benefits should reflect the positive impacts or externalities that Green Elk & Company creates for the environment and society through its products or services, such as reducing emissions, improving health, or enhancing education. The eco-social costs should reflect the negative impacts or externalities that Green Elk & Company causes for the environment and society through its products or services, such as increasing waste, depleting resources, or harming biodiversity.
The other options (A and B) are not correct for the sequence of steps to apply the Sustainable Business Model Canvas, because they either skip or misrepresent some of the steps in this tool. For example:
Option A is not correct because it does not include assessing and defining the value propositions for the small size farms customer segment, which is a crucial step to understand and communicate how Green Elk & Company creates value for its customers. It also suggests defining the cost structure and revenue streams before defining the customer segments and value propositions, which is not a logical order since the latter determine the former.
Option B is not correct because it does not include identifying relevant key activities, key resources, and partners, which are important aspects of executing a business model. It also suggests retrieving the documentation for the solutions that need to be integrated instead of assessing and defining the value propositions for the small size farms customer segment, which is not relevant for designing a new business model.
