Practical information
1. SAP Digital Transformation Methodology
SAP has a unique methodology of digital transformation, which mainly focuses on three questions: Why should we make digital transformation? What can digital transformation bring? How to do digital transformation? Implemented in a unified process in each project:
- Find pain points and causes from the current situation, and formulate corresponding business objectives.
- Select the appropriate information products and use the appropriate functions within the products to match the business requirements.
- Make a preliminary digital transformation structure, business structure, data structure, application structure and technical structure.
- It is necessary to prioritize the needs of enterprises and gradually realize them.
- According to the priority, specify the road map and strategic deployment of enterprise digital transformation, and gradually conquer it.
- Select the appropriate implementation path for each product in the roadmap.
02. How to choose the implementation of S/4HANA
Combining the results of analyzing why digital transformation is necessary in the methodology of digital transformation;
1. To what extent does the existing business system meet the needs of the business?
2. Do you want to protect the historical IT investment?
The implementation method also affects the formulation of the road map for digital transformation.
-Upgrade and transformation means that enterprises will quickly upgrade the digital platform through technical means so as to meet the business needs in time.
-The new implementation is to abandon the old technology platform and historical burden, and realize as many technical capabilities as possible at one time on the S/4 platform to meet business needs.
03. How to help enterprises go to the cloud?
Methods The overall implementation methods are divided into the following two types:
- Business-oriented re-implementation requires users to participate in the whole process of the project, from early demand investigation to blueprint formulation to functional specification and various tests.
- Upgrade (S/4 Conversion) is a technology-oriented technology upgrade, which directly converts the original ERP system into S/4, keeping the functions and data of the original system as much as possible.
04. Main work involved in S/4 HANA upgrade and transformation
- Preparation stage: compare the existing ERP system with S/4 system through readiness inspection and investigation, and find out the change points in time.
- Pre-conversion stage: data archiving and self-developed code management cleaning to reduce data volume and downtime, CVI adjustment and data consistency check.
- Conversion stage: system upgrade, data relocation and logistics data conversion. The downtime is related to the amount of data.
- Post-conversion stage: self-developed code adjustment, financial data conversion and post-processing of each module upgrade.
5. Self-developed code adjustment related process
In the process of migration, the self-developed code needs to be adjusted for the following reasons:
The first category: code unavailability due to database replacement.
Category II: The standard code has changed due to the system upgrade.
The third category: due to the change of S4 simplification, the original self-developed standard object has changed due to the simplification of table structure, and it needs to be adjusted properly before it can be used.
The fourth category: it belongs to the adjustment of good to have. Many original programs that are being calculated on the application server can sink into HANA database for calculation through CDS View and other technologies, thus greatly improving the performance.
For these four types of self-developed code adjustments caused by upgrading to S/4HANA, SAP provides tools to help users simplify their workload and reduce cumbersome operations.
06.Compatibility View & CDS View
- The table streamlined by S4HANA uses the Compatibility View of the same name to realize backwards compatibility.
- Reduce the workload of system conversion and upgrading.
- It is a transitional scheme, which can be optimized step by step in the long run, so that Z program can directly access the optimized bottom table.
07.SAP S/4HANA MOVEMENT partial acceleration tool
Not only for self-developed code, SAP provides rich digital tools to help customers accelerate the implementation of migration projects according to different digital transformation stages, including six stages: planning, architecture, customized code, deployment, integration and migration.
08.SAP enabling services and tools
For super-large enterprises and multinational companies, in the process of digital transformation, they will face an important topic: how to effectively empower many multinational personnel?
Before the enterprise does the S/4HANA project, IT needs to let the IT staff inside the enterprise know what capabilities S/4 can provide. After a certain understanding, the enterprise does not need to do a lot of self-development, try to use standard functions and reduce operation and maintenance costs. SAP also provides corresponding tools to help customers accelerate transformation.
09. Simplify and accelerate the SAP S/4HANA journey
By making full use of SAP's unique expertise, systematic methods and practices driven by results, enterprises can find a high-performance, sustainable solution for future innovative implementation.
SAP-led: With the help of SAP services, it is compatible with SAP best practices in the end-to-end delivery mode to speed up the implementation of SAP S/4HANA.
Customer/partner leadership: led by high-quality partners such as Decision, the project is implemented with SAP solutions, and SAP provides technical support. The original SAP factory is more inclined to this mode which is beneficial to the ecological development of SAP.
