SAP Business Suite 4 HANA (more simply called SAP S/4HANA) is the latest version of SAP's ERP. Available since 2015, S/4HANA replaces SAP ECC6 and brings many functional evolutions and technical innovations to increase the productivity of companies and simplify the work of users. As a reminder, the end of maintenance for SAP ECC6 is set for December 31, 2027 (2030 in the context of extended maintenance with an increased cost) and companies using this version must include the conversion/migration to SAP S/4HANA in their roadmap before this deadline in order to guarantee continuous maintenance of their system.
The latest version of SAP S/4HANA is 2021, available since October 2021.
Companies are facing cross-functional challenges in their business functions. They must now also manage the accelerated pace of adoption of solutions and therefore of their ERP. This trend has its origins in the finance, HR, purchasing and CRM functions, which have reclaimed their information systems and wish to rely on more flexible, simpler and more user-friendly solutions.
SAP S/4HANA responds to these wishes by offering a redesigned ergonomics, decision support functions integrated into the transactional processes and better collaboration between partners and customers. Data is used more dynamically and is accessible in real time, allowing companies to respond more quickly to their needs. The user experience is significantly improved.
The integration in S/4HANA of many functionalities previously offered in complementary SAP solutions (SRM, SCM, CRM...) allows to rationalise and simplify the SAP landscapes of the customers.
Applium's SURFtoS/4 offer brings together methodology, tools and expertise to support SAP ECC6 customers in their S/4HANA migration. It relies on experts covering all the functional and technical areas required for the project, under the responsibility of project managers dedicated to S/4HANA migration projects.
It covers the following 4 major phases:
The first phase proposed in the SURFtoS4 offer is the scoping phase. It is not mandatory, but strongly recommended. Indeed, SAP customers do not always know how to move forward and prepare their migration to S/4HANA and ask themselves many questions:
You can obtain the answers to all these questions by entrusting our experts with an S/4HANA scoping exercise. The SURFtoS4 framework consists of a packaged and fixed price offer:
The SURFtoS4 scoping deliverables will give you a clear vision of your S/4HANA roadmap to present to your management and your teams. They are mainly composed of :
The POC consists of the provision of an S/4HANA instance, a copy of your SAP ECC6 instance, on Microsoft Azure or on your infrastructure. The objective of the POC is to allow your users and your IT teams to become familiar with and discover S/4HANA at their own pace before carrying out the migration. It's possible to evaluate technological innovation, new functionalities and the Fiori interface of SAP S/4HANA. The POC (Proof Of Concept) matches to a blank run on your SAP system. It runs on a copy of your SAP Production instance and allows you to:
This export can be hosted on site. If there is no infrastructure that meets the recommended requirements, Applium recommends using a Microsoft Azure virtual machine. In both cases, costs are to be expected and will be added to the cost of the POC.
The method is to perform an import on a clone machine in order to prepare the ECC6 version for its conversion.
Depending on the effort agreed to allocate to the POC, adjustments to make this environment more relevant can be made.
The completion of the POC can take place over a period of 2 to 4 months depending on the options chosen.
At the end of the conversion and technical adjustments, APPLIUM undertakes to leave free access to this environment for the duration desired by the customer.
SAP ECC6 customers will need to migrate to SAP S/4HANA in the next few years and there are several approaches to perform this migration, addressing different objectives.
The choice will essentially be made between the following two scenarios:
There is not one and only method to migrate to S/4HANA. The methodology must fit all the particularities of the organization and it priorities. You can choose to set up S/4HANA on « Greenfield », meaning without any SAP conversion tool or scale up a migraition or selectively migrate certain or specific parameters from your old SAP ECC6 system. This is the preferred approach for customers whose ECC6 system is no longer in line with the management processes and rules. However, it is an approach that will turn out to be more expensive and put more strain on your business teams. It will also require more change management for users.
The Brownfield approach (technical migration) is a faster implementation and lower cost. The new S/4HANA functionalities may be deployed gradually over time, depending on the needs and availability of the IT teams. The scoping phase is essential to determine the best approach depending on the background.
Once the migration has been completed and the first improvements adopted by users, the IT will have access to many features and innovations that couldnn't exist with SAP ECC6: Robot Process Automation, digital marketing, provision calculation proposals, predictive analysis, cash management, closing cockpit, 360° Customer, supplier evaluation, purchasing Workflow, item coverage, DDMRP, resource planning, advanced eWM functions, rescheduling of OFs...
Depending on the business priorities, Applium can help you deploy these new innovative features with peace of mind and continue to increase the efficiency and satisfaction of the users.
Applium recommend, whenever it's possible, a Brownfield migration, for several reasons :
During a Brownfield project, the conversion method is similar to the POC : An import on a clone machine is carried out in order to prepare the ECC6 version for its conversion.
Working closely with your teams, Applium can support you and take responsibility for all aspects of the project:
During the technical migration phase itself:
During the following optimization phases.
Once the migration is effective, you have an up-to-date technical base allowing you to seize the opportunity to enrich your solution with new functionalities and technologies, and to benefit from the power and intelligence of an ERP. " New generation " :
The transition to S/4HANA also requires taking into account the following
Applium is used to 6 typical S/4HANA conversion project sizes to which are associated a price and a schedule:
The determination of the size corresponding to each customer is done through a questionnaire covering several criteria:
The concept of t-shirt size is a first pricing approach, the study of the situation of each customer makes it possible to define an appropriate response for each support proposal.
|Certification 10 Steps to S4 Conversion||What are other SAP ECC6 customers planning?||Applium experience in the context of SAP migrations|
Organized by SAP and open to a few partners in each country, the 10 Steps to S4 Conversion program aims to certify SAP integrators as part of ECC6 customer conversion projects to S/4Hana. The program consists of providing partners with an ECC6 Ehp6 environment on Microsoft SQL Server for conversion and controlling each step of the conversion.
n April 2019, IDC carried out a study among 300 companies using SAP ECC6 (10 countries on 3 continents, companies with 1,000 to 25,000 employees, IT Director or business profiles).
The main reasons for switching to S/4HANA are:
The businesses highlight the capabilities of S/4HANA in terms of reporting, analysis, predictions and simulations offered by the solution and the significant reduction in working time for users (for the transactional, as well as for the reports).
Applium has carried out dozens of SAP version upgrade projects (S/4HANA, Ehp, Hana, OS/DB, infrastructure change) over the past 15 years.
