SAP S/4 Hana Migration
SAP S/4HANA is a real-time ERP solution and the successor to SAP's previous core product, SAP ERP ECC. The S in the product name stands for Simple, the 4 for the fourth product generation, and HANA (High Performance Analytic Appliance) describes the underlying database technology.
Using the SAP HANA in-memory platform radically simplifies the data model. Companies can execute transactions in real time, analyze data, and manage their business efficiently.
With SAP Fiori, users receive a personalized, role-based user interface, as they are familiar from the consumer world – and often also expect in the business world today. Processes are supported consistently with SAP S/4HANA, eliminating media disruption. Switching to a business warehouse, for example, to create a report or performing manual steps outside of SAP are no longer necessary.
With SAP S/4HANA, customers benefit from significantly improved performance. By leveraging HANA's data compression technology, data requirements can be reduced by up to 50 percent; reports can be created many times faster; and users can analyze data in real time.
While SAP ERP was referred to as modules, SAP itself refers to SAP S/4HANA as processes that cover the entire business and are coordinated with one another. The current version of SAP S/4HANA covers the following functional areas:
Sales & Marketing
Finance
Manufacturing
Supply Chain
service
Asset Management
R&D / Engineering
Sourcing & Procurement
Upgrading to SAP S/4HANA is a complex process that requires careful planning, preparation, and execution. There are different methods and approaches, depending on the company's individual needs and current SAP environment. Here is a general description of how an upgrade to SAP S/4HANA might proceed:
Evaluation and planning: The first step is to assess the need for and benefits of an upgrade to SAP S/4HANA. This includes reviewing the functionalities and benefits of S/4HANA and identifying the company's specific requirements and goals. A detailed migration strategy is developed to plan the upgrade process.
Preparation and system analysis: Before the actual upgrade begins, a comprehensive analysis of the current SAP environment is conducted. This includes a review of existing systems, customizations, data quality, and other relevant factors. Compatibility checks are also performed to ensure that existing applications and extensions are compatible with S/4HANA.
Data migration and preparation: Data migration is a critical aspect of the upgrade. A detailed plan is created to extract, transform, and load data from the existing system into the new S/4HANA system. The data is cleaned, converted, and validated to ensure a smooth transition.
Custom code analysis and adaptations: If the existing SAP system contains custom extensions and adaptations, these must be reviewed for S/4HANA compatibility and adapted if necessary. This may include the use of new S/4HANA functionalities and the replacement of outdated functions.
Testing: To ensure the upgrade is successful and business processes function properly, extensive testing is conducted. This includes functional testing, integration testing, and performance testing.
User training and preparation: Since S/4HANA may involve some changes in the user interface and functionality, it is important to adequately train and prepare users for the new system. This will help ensure a smooth transition to S/4HANA.
Implementing the upgrade: After all preparatory steps have been completed, the actual upgrade to SAP S/4HANA begins. This process can take some time depending on the size and complexity of the SAP environment and requires careful monitoring to identify and resolve potential issues early on.
Follow-up and support: After the upgrade, the IT team continues to provide support to ensure that the S/4HANA system runs smoothly and any issues are resolved.
Upgrading to SAP S/4HANA is a significant investment, but it can deliver significant benefits in terms of efficiency, speed, and functionality to help companies meet the challenges of the digital economy.
