Supporting Alliander’s journey to SAP S/4HANA

There are risks in undertaking any big treasury transformation project, but the risks of not adjusting to the changing world around you can be far bigger. Recognizing the potential pitfalls of relying on an outdated (and soon to be unsupported) SAP ECC system, Alliander embarked on a large-scale, business-wide transition to SAP S/4HANA. Zanders advised on the Central Payments and Treasury phase of this project, which completed in May 2024.

A future-focused perspective

Network company, Alliander, is the Netherlands’ biggest decentralized grid operator, responsible for transporting energy to households and businesses, 24 hours a day, 7 days a week. As a driving force behind the energy transition, the business is committed to investing in innovation - and this extends to how they are future-proofing their business operations as well as their contribution to shaping the sustainable energy agenda.

With their SAP ECC system approaching end of life, Alliander embarked on a company-wide switch to SAP S/4HANA. However, transitioning to SAP’s newest ERP platform is not just another simple upgrade, it’s a completely new system built on top of the software company’s own in-memory database HANA. For a business of Alliander’s size and complexity, this is a huge undertaking and a lengthy process. In order to minimize the disruption and potential risks to mission-critical business systems, Alliander has started the transition early, breaking down the implementation into a series of logically ordered phases. This means individual business areas are migrated to S/4HANA as separate projects.

“In finance, this transition started about four years ago with the transition of Central Finance to S/4—that was the first stepping stone,” says Thijs Lender, Financial Controller and Alliander’s Project Owner for SAP S/4HANA in Finance. “The second major project was Central Payments and Treasury. From a business point of view, this was the first real business finance process that we implemented on S/4.”

Central Payments and Treasury was selected as a critical gateway to moving other business areas to the new target infrastructure, for example, purchasing. It was also an ideal test ground for the migration process from ECC to S/4HANA as Alliander’s cash management processes operate in relative isolation, therefore presenting a lower risk of collateral damage across other business operations when the department moved to the new system. ''Treasury and Central Payments is at end of the of the source-to-pay and order-to-cash process—it’s paying our invoices and collecting money,” explains Guido Tabor, Digital Lead Finance at Alliander. “This means it could be moved to the target architecture without impacting other areas.”

Greenfield or brownfield?

The two most common pathways to SAP S/4HANA are a greenfield approach and a brownfield approach. For a brownfield migration a company’s existing processes are converted into the new architecture. In contrast, the greenfield alternative involves abandoning all existing architecture and starting from scratch. The second is a far more extensive process, requiring a business to often make wide-ranging changes to work practices, reengineering processes in order to optimally standardize their workflows. As Alliander’s business had changed significantly over the period of running SAP ECC, they recognized the benefit of starting from a clean slate, building their new ERP system from scratch to meet their future business needs rather than trying to retro fit their existing system into a new environment.

“We really wanted to bring it back to best practices, challenging them and standardizing our processes in the new system,” adds Thijs. “In the old way, we had some ways of working that were not standard. So, there were sometimes tough discussions, and we had to make choices in order to achieve standard processes.”

A collaborative approach

While the potential benefits of greenfield migrations are substantial, untangling legacy processes and building a new S/4HANA system from scratch is a complex undertaking. Success hinges on the collaboration of various stakeholders, including experts with understanding of the inner workings of the SAP architecture.

“From the very beginning, we didn't see this as an IT project,” Guido says. “IT was involved but also the business - in this case, finance from a functional perspective, and also Zanders and the Alliander technical team. It was really a joint collaboration.”

Zanders worked alongside Alliander right from the early stages of the Central Payments and Treasury project. ­From helping them to strategically assess their treasury processes through to planning and implementing the transition to SAP S/4HANA. Having worked with the business previously on the ECC implementation for Central Payments and Treasury, Zanders’ knowledge of Alliander’s current environments combined with their specialist knowledge of both treasury and SAP S/4HANA meant the team were well placed to guide the team through the migration process. The strength of the partnership was particularly important when the timing of the deployment was brought forward.  

“Initially we wanted to go live shortly before quarter close” Guido recalls “Then at the beginning of January, we had a discussion with our CFO about the deployment. With June 1 being very close to June 30 half year close, we decided we didn't want to take the risk of going live on this date, and he challenged us to move it back to the middle of May.”

What became really important was having a partner [Zanders] who helps you think out of the box. What's the possibility? How can you deal with it? While also being agile in supporting on fast changes and even faster solutions.

Adopting a 'Fix It' mindset

With the new deadline set, the team were encouraged by the CFO to adopt a ‘fix it’ mindset. This empowered them to take a bold, no compromises approach to implementation. For example, they were resolute in insisting on a week-long payment freeze ahead of the transition, despite pleas for leniency from some areas of the business. This confident, no exceptions approach (driven by the ‘fix it’ mentality) ensured the transition was concluded on time leading to a seamless transition of Central Payments and Treasury to the new S/4HANA system.

“This was a totally new perspective for us,” says Guido. “With go live processes or transitions like this, there will be some issues. But it didn't matter what, it didn't matter how, we just had to fix it. What became really important was having a partner [Zanders] who helps you think out of the box. What's the possibility? How can you deal with it? While also being agile in supporting on fast changes and even faster solutions.”

Central Payments and Treasury project went live on S/4HANA in May 2024, on time and with a smooth transition to the new system.

“I was really happy on the first Monday after go-live and in that early week that there weren't big issues,” Guido says. “We had some hiccups, that's normal, but it was manageable and that's what is important.”

This project represented an important milestone in Alliander’s transition to SAP S/4HANA. Successfully and smoothly shifting a core business process into the new architecture clearly progressed the company past the point of turning back. This reinforced momentum for the wider project, laying robust foundations for future phases.
