SAP S/4HANA best practices: what it takes to get real value from your SAP upgrade

The Introduction

SAP S/4HANA is no simple update - it's a game-changer. The chance to shake up how your business really operates, and puts real power in your hands.

But sadly, lots of organisations look at S/4HANA through one lens only. Get up and running. As fast and as safely as possible.

That approach is understandable. But it often means missing the bigger picture.

This blog takes a look at what best practice SAP S/4HANA really means in the real world. Where businesses go wrong, and how to get some real value out of S/4HANA, especially when it comes to supply chain operations. We'll be looking at how PreBilt helps bridge the gap between a modern SAP core and the people who use it every day.

What does "best practice SAP S/4HANA" actually mean?

Best practices in S/4HANA aren't about just following some sort of formula or switching on every standard process without thinking.

It's all about finding that balance.

True best practice SAP S/4HANA means:

• Using SAP standard where that makes sense for you

• Sorting out your processes before automating them

• Designing the system around users, not just the technology

• Making decisions that'll still make sense in five years' time

Best practice in S/4HANA isn't about following SAP Best Practices to the letter, it's about finding a practical way to get things done that fits your business.

In other words, best practice is all about what works in practice, not just what you're told is the way to do it, and SAP Best Practices are a good starting point for central business areas like finance and sales, because they've been proven in loads of different industries.

Start with business processes, not the tech

One of the most common mistakes in S/4HANA programmes is starting with the system design.

True best practice SAP S/4HANA starts earlier than that, with some proper strategic planning, clear business objectives, and the expertise to assess what you're doing with your business processes before you migrate.

It starts by asking a few key questions:

• Which processes are working well for you today?

• Which ones are still around because of old limitations?

• Where is complexity holding people back?

You need to evaluate the main deployment paths early, such as Greenfield, Brownfield or a hybrid approach if that works for you.

S/4HANA works best when it supports simple, well-defined standard processes. Migrating broken or overly complex workflows from legacy systems or tightly coupled existing systems into a faster system just gives you a faster route to more problems.

Simplify first. Then move, following a structured approach with the critical things that need doing in the right order, and using an agile delivery discipline to keep things on track.

Don't customise just for the sake of it

SAP S/4HANA Cloud and SAP Best Practices in SAP S/4HANA Cloud Public Edition give you a rich set of standard capabilities and predefined templates as a starting point before you start customising. Not using them would be a bit of a mistake.

True best practice SAP S/4HANA means:

• Questioning any custom developments

• Understanding why something was built in the first place

• Asking whether that need still exists

Those standard templates often reduce the need for custom ABAP programming and make it easier to adopt new features.

Customisation isn't inherently bad. But unnecessary customisation increases cost, complexity and future upgrade effort.

Design for users, not for transactions

SAP S/4HANA comes with a Fiori-based interface, but the user experience still makes or breaks adoption.

True best practice means designing the system around:

• Roles, not transactions

• Tasks, not menu paths

• Real working conditions

Personalised dashboards can help end users stay on top of role-based work, but only when the design matches real tasks.

That matters most in execution-heavy areas like supply chain, warehousing and manufacturing, where users are time-poor and processes are moving fast.

If people have to fight the system, workarounds will appear and value will disappear.

That's where many S/4HANA programmes go wrong. The core may be modern, but the experience still feels like hard work, which slows user adoption.

How PreBilt supports best practice SAP S/4HANA

This is where PreBilt comes in.

PreBilt is designed to sit within the broader SAP solutions, EWM for example, and make everyday supply chain processes easier to do. It doesn't replace SAP, it just makes it work better for the people using it.

As part of a best practice SAP S/4HANA approach, PreBilt helps by:

• Turning complex SAP processes into guided, task-based workflows

• Reducing the need for users to understand SAP transactions

• Supporting mobile and shop-floor users who don't sit at desks

• Improving adoption without adding customisation to the SAP core

Those guided workflows and intelligent automation can reduce manual efforts by 40% in execution-heavy processes.

In simple terms, PreBilt helps businesses keep their S/4HANA core clean, while still delivering a user experience that works in the real world.

Best practice SAP S/4HANA in the supply chain

Supply chains are where SAP S/4HANA can really bring its A game. But only if you do it right.

Best practice SAP S/4HANA supply chain projects focus on:

• Getting a clear view of the whole process, not just bits and pieces

• Catching exceptions before they become problems, rather than constantly checking in on things

• Using real time data to make informed decisions, with some predictive analytics thrown in - not just reporting for the sake of it

SAP S/4HANA's in memory architecture lets you get insights into your supply chain business processes a lot faster and makes your operations a lot more efficient. PreBilt makes sure that those insights actually make it to the warehouse floor and not just to the dashboard.

By guiding users through the whole receiving, picking, packing and moving process, PreBilt helps SAP S/4HANA deliver value where it actually counts.

Data counts more than ever

SAP S/4HANA is unforgiving when it comes to bad data, so migrating requires better data deduplication, cleansing and overall quality, not just some general data quality work.

Best practice SAP S/4HANA puts data quality right at the top of the agenda:

• Get your master data spot on

• Make sure everyone knows who's responsible for it

• Agree data standards across the whole business

And it's even more important when SAP S/4HANA connects to other systems and apps.

Bad data doesn't just cause headaches with reporting, it also chews up trust in the system and slows adoption down.

PreBilt helps out with data quality by checking what's being done at the point it's happening. The right scan. The right item. The right location. Every time.

Which means you've got good data flowing back into SAP S/4HANA, without having to rely on people double checking it.

Don't just stop at go live with SAP Activate methodology

One of the biggest shifts in best practice SAP S/4HANA thinking is realising that go live isn't the finish line, it's just the start.

Good organisations plan for long term success by:

• Making continuous improvements

• Regularly reviewing and refining processes

• Adopting new features and SAP capabilities over time, rather than all at once

Continuous performance testing helps keep your system running smoothly after go live, and performance tuning improves user productivity, reduces downtime and supports system performance.

Because PreBilt is configurable rather than hard coded, it helps you with that mindset. Processes can evolve without having to re-engineer the SAP core, which makes S/4HANA flexible and adaptable as the business changes, without sacrificing stability.

The role of partners in best practice S/4HANA

SAP provides the platform. Partners make sure it gets used effectively and good partners typically work within the SAP Activate methodology, getting business leaders, key stakeholders and the project team involved from the get go.

Best practice SAP S/4HANA projects rely on partners who:

• Know SAP inside out

• Know supply chain operations just as well

• Know when to follow standard procedures and when to put up a fight

• Focus on outcomes, not just getting the project done on time

Tools like PreBilt work best when combined with experienced SAP supply chain specialists who understand how things really work on the ground.

The S/4HANA best practice mistakes to avoid

Even with well run programmes, teams can still trip up if they don't do things the right way.

Common pitfalls include:

• Thinking S/4HANA is just a technical migration

• Over customising too early ‘just in case'

• Designing for perfect processes rather than real ones

• Ignoring what happens on the ground and what users actually need

• Underestimating the importance of change management

Best practice SAP S/4HANA is as much about people as it is about technology, and business objectives should drive decisions throughout the programme.

Frequently asked questions

Is SAP best practice always right for every business? Not always. SAP best practices are a great place to start, but they're often based on generalised standard processes that may not fit how your business operates.

Does best practice mean no customisation? No, that's a common misconception. It's about using customisation thoughtfully and only where you really need to. Being careful not to mess with the S/4HANA core in ways that'll cause you more hassle than they're worth.

How does PreBilt fit with SAP S/4HANA? PreBilt runs alongside S/4HANA, helping with the day-to-day stuff and user adoption while keeping your core system tidy and upgradable.

Where does S/4HANA deliver the fastest value? In areas like supply chain, warehousing and logistics, you can often see benefits pretty quickly if you focus on making the user experience better alongside the core functionality, which in turn makes a big difference to operational efficiency.

The bottom line

SAP S/4HANA best practice isn't about copying someone else's template & putting it in your business, that's just going to lead to problems.

It's about thinking things through with a bit of strategy and taking a sensible approach.

First of all, simplify things before you try and build on them. Then, design with your people in mind. Don't let the core system get all cluttered up. And finally, make sure you've got the tools you need to make execution happen properly.

If you do it right, with the right tools like PreBilt, S/4HANA can be so much more than just a new system. It's a platform that'll actually help your business grow and achieve your longer term goals.
