With SAP’s planned reduction in SAP ECC support levels for 2027, it’s becoming increasingly important for integrated energy companies to start planning for their response. These are important systems, after all. Invoicing, supply chain operations, and maintenance are performed using SAP.
Energy companies cannot just hope that deadlines are extended and problems postponed because the risks are too great. Without regular ERP updates, service and support, it’s not a starting point after all. they must act now.
Upfront planning is important to decide whether to choose a greenfield implementation of a new ERP system, a brownfield migration to SAP S/4HANA, or a hybrid.
start with a blank slate
A greenfield project starting from scratch can have a wide range of benefits depending on your organization’s specific needs. Without having to deal with legacy systems, companies have complete freedom to redesign and orient their processes.
If your organization’s existing solution no longer meets your current business needs, data quality is poor, or you need to redesign your organizational structure, a new implementation may be your best option.
It may take more effort, but the end result is a solution designed to meet your organization’s operational requirements and easily adaptable as your business evolves. Companies also benefit from well-defined business processes and a clear and complete set of documentation that makes it easier to support their solutions.
On the flip side of the coin, businesses can lose historical data. Maintaining access to this data and ensuring legal compliance requires some up-front consideration, but it’s usually not a big deal or a big detractor.
Brownfield Alternatives – Same Structure, Enhanced Benefits
In contrast to the greenfield option, a brownfield implementation of SAP S/4HANA starts with the existing system with only a few key changes.
This approach can be less costly to the company than deploying an entirely new project because it does not require rebuilding a function that works well for the company. Moreover, it can be done without disturbing his existing ERP implementation.
However, this kind of approach has to be done all at once, which can be difficult if the migrating company has limited tolerance for downtime. Likewise, the final setup can be cumbersome and rigid. While this organization is focused on executing transformations, it typically takes away virtually all the baggage of data, processes, code, and so on. At some level, this can reduce long-term agility, and is mostly unacceptable if your business changes significantly over time and your platform contains customizations to fit outdated business models. It makes no sense.
Additionally, today’s popular ERP implementation model keeps the core “clean” and development is done on a specific platform instead of the core. It’s important to note that applying this approach to migration would require a significant amount of rework, which could potentially be done in a second implementation phase. However, please also consider that making such changes to a new production system may increase operational risk. Often mitigated by extra testing that slows the pace. Some believe that this approach lacks agility and may take time to achieve feature parity and simplification across the board.
A hybrid approach may be the best way forward
Each approach has its strengths and weaknesses, but there is another way to separate the system from the data to simplify the migration process and unlock the potential for structural change.
In this method, data is transferred by SAP or its partners from the ERP system to the new SAP S4/HANA implementation. This approach provides flexibility by allowing the company to reuse parts of his existing ERP system he likes while redefining other parts. Typically, this is done by an application, allowing companies to redesign things like procurement and logistics while retaining the finance, sales, and marketing modules.
This is a great way for companies looking to scale, bring new business units online or expand into new countries and get them up and running in phases. They get the option to leave a lot of old data that they don’t need. This approach also helps reduce the risks associated with the Big Bang “going live.” It also reuses some application areas, reducing the time and expense of reimplementation.
Regardless of the final choice, migrating companies should assess their existing processes and be ripe and ready to take action that will bring immediate benefits and simplify their migration to S/4 HANA. Requires the assistance of an expert who can identify opportunities for process improvement. .
We offer a variety of options. Every business is different, and for each business, whether greenfield, brownfield, or a hybrid of the two, choosing the right migration path depends on the nature of the organization and its unique circumstances. One thing is for sure, with the 2027 SAP deadline fast approaching, companies have no choice but to do nothing. However, there are many considerations in choosing the right migration path. The good news is that if an organization makes the right decisions and follows the right implementation processes, it can lay the foundation for future success.
