SAP provides several tools to facilitate the maintenance of SAP S/4HANA Cloud systems following a release upgrade, ensuring that customers can smoothly transition to the latest functionalities and improvements:
* What's New Viewer Tool: This tool is invaluable for understanding the changes and new features introduced with each SAP S/4HANA Cloud release. It provides detailed descriptions of new functionalities, improvements, and changes in the system, helping customers to adapt their processes and leverage new capabilities effectively. It serves as a guide to explore and understand the enhancements that come with each upgrade.
* Test Automation Tool: Post-upgrade, it's crucial to ensure that existing functionalities continue to work as expected and new features are correctly implemented. The Test Automation Tool allows customers to automate testing of business processes, significantly reducing the time and effort required for testing after a release upgrade. This tool helps in identifying any issues arising from the upgrade early in the process, ensuring a smooth transition to the new release.
These tools are designed to assist customers in navigating the complexities of system upgrades, ensuring that they can make the most out of new features while maintaining their existing system's stability and performance.

Fiscal year variant and group currency are activities that are applied to the entire system and cannot be changed after confirmation in SAP Central Business Configuration. These activities are part of the system provisioning step, which is the first step in the implementation process. Once the system provisioning is completed and confirmed, the system is locked for these activities and any changes would require a new system provisioning. Scoping and configuration activities, on the other hand, are not applied to the entire system and can be changed later on in the project experience step, which is the second step in the implementation process. Scoping and configuration activities allow the user to adapt the preconfiguration content to their company's needs and extend the configuration for areas not equipped with preconfiguration content.

In the Product-Specific Configuration Phase within SAP Central Business Configuration, several key activities can be performed to tailor the SAP S/4HANA Cloud system to meet specific business needs:
* Add new sales organizations: This activity involves setting up new sales organizations within the system, defining the structure of the sales department, and aligning it with the company's sales strategies and territories. This setup is crucial for managing sales processes, customer relationships, and sales reporting.
* Change approval thresholds: Modifying approval thresholds is an essential configuration activity that adjusts the approval limits for various transactions, ensuring that the approval process aligns with the company's internal control and governance policies. This can involve setting different thresholds for purchase orders, expense approvals, and other financial transactions.
* Add blocking reasons for billing: This configuration activity allows the company to define specific reasons for blocking billing documents, ensuring that billing does not proceed under certain conditions until the issues are resolved. This is critical for maintaining accurate and compliant billing processes.
These activities are part of the detailed configuration work that tailors the SAP S/4HANA Cloud system to the specific operational needs of the business, ensuring that the software supports the company's unique processes and policies.

The SAP Fiori Launchpad provides embedded support offerings that can help users learn and perform tasks more efficiently. These offerings include:
* Digital assistance from generative AI (SAP Joule): This is a conversational AI assistant that can answer user questions, provide guidance, and execute tasks using natural language. SAP Joule can be accessed by selecting the headphones icon in the top right corner of the SAP Fiori Launchpad and choosing the chat option.
* Recorded system simulations from the Learning Center: These are interactive tutorials that show users how to perform common tasks and scenarios in the SAP S/4HANA Cloud system. Users can access the simulations by selecting the question mark icon in the top right corner of the SAP Fiori Launchpad and choosing the graduation cap icon. The simulations are created with the SAP Enable Now tool and can be customized by customers if needed.
* Video tutorials from the SAP Help Portal: These are short videos that explain the features and functionalities of the SAP S/4HANA Cloud system and the SAP Fiori Launchpad. Users can access the videos by selecting the question mark icon in the top right corner of the SAP Fiori Launchpad and choosing the megaphone icon. The videos are also available on the SAP Help Portal website.
The other options are not embedded support offerings in the SAP Fiori Launchpad. Recorded webinars from the SAP Learning Website and assessment questions from the SAP Learning Hub are external learning resources that users can access separately from the SAP Fiori Launchpad.

* Sandbox system: This is an optional system that can be used to explore the SAP S/4HANA Cloud Public Edition capabilities and features before the implementation project starts. It is not connected to the starter system or the test system and does not have any data migration or configuration tools. It can be refreshed on demand by the customer1.
* Starter system: This is the first system that is provisioned for the customer after the contract is signed.
It is used to perform the fit-to-standard workshops, where the customer validates the standard processes and identifies the gaps and requirements. It also serves as the configuration system, where the customer configures the business processes using the SAP Central Business Configuration tool. The starter system is connected to the test system and can transfer the configuration and master data to it2.
* Test system: This is the second system that is provisioned for the customer after the starter system is configured. It is used to perform the integration testing, user acceptance testing, data migration, and cutover activities. It also serves as the production system, where the customer runs the live business processes after the go-live. The test system is connected to the starter system and can receive the configuration and master data from it3.
The systems that are not used to implement SAP S/4HANA Cloud Public Edition for a customer are:
* Trial system: This is a system that can be used to experience the SAP S/4HANA Cloud Public Edition solution for a limited time. It is not connected to any other system and does not have any data migration or configuration tools. It is not part of the implementation project and does not require a contract4.
* Development system: This is a system that can be used to develop custom applications or extensions using the SAP Business Technology Platform. It is not part of the SAP S/4HANA Cloud Public Edition landscape and does not have any data migration or configuration tools. It requires a separate contract and license.
