SAP S/4HANA: the modern ERP platform that's changing the game for real-time, connected business operations

A new way of thinking with SAP S/4HANA

SAP S/4HANA is more than just a new ERP system - it's a game-changer for organisations that want to do business in real time. It's a major shift away from the complex, clunky ERP environments of the past and towards a sleek, simplified platform that's built for speed and agility.

What we're after with SAP S/4HANA

SAP S/4HANA is designed to:

• Simplify business processes so you can get on with the day job

• Give you real-time data and insights that help you make better decisions

• Make it easy to integrate all your systems, so they work together seamlessly

• Keep up with the latest technologies, like cloud and automation

If you're involved in reviewing SAP strategy or shaping transformation messaging, your goal should be to get a handle on what S/4HANA is all about, how it works, and how you can use it to boost business performance.

What SAP S/4HANA actually means

SAP S/4HANA stands for: SAP Business Suite 4 SAP HANA. It's the next big thing in ERP software, built on the SAP HANA in-memory database. SAP launched S/4HANA in 2015 - it's the fourth generation of the software.

The key differences between S/4HANA and older systems are:

• It processes data in real time, so you can respond to changes as they happen

• It simplifies data structures, so you can focus on the stuff that matters

• It integrates all your business processes, so everything works together like clockwork

In short, S/4HANA is the digital core of modern SAP environments - the heartbeat of your business.

How SAP S/4HANA works

S/4HANA is built on a super-simplified architecture that makes life easy for users and developers alike.

It includes:

• The SAP HANA database, with in-memory processing that's lightning fast

• The application layer, where all the business processes happen

• A friendly user interface (SAP Fiori) that makes it easy to get things done

• An integration layer (SAP Business Technology Platform and APIs) that lets you hook up all your systems and data

This architecture means you get:

• Faster data processing, so you can respond to changes quickly

• Real-time analytics, so you can make better decisions

• A simplified system design that makes it easy to develop new apps and services

And the best part? These layers all work together to give you a broader business technology platform - and the in-memory HANA foundation takes advantage of all the latest processing power.

Deployment options for SAP S/4HANA

S/4HANA can be deployed in different ways to suit your business needs.

S/4HANA Cloud (public cloud)

• Fully managed by SAP, so you can just focus on running your business

• Standardised processes, so you can get on with the day job

• Regular updates, so you're always working with the latest features and functionality

• Uses a subscription model, so you only pay for what you use

• Available in 55+ countries and 32+ languages, so you can do business globally

S/4HANA private cloud

• A dedicated environment that gives you more control over the config

• More flexibility and customisation, including support for custom code

• Can fit a hybrid model, so you can split processes between environments

S/4HANA on-premise

• Hosted internally or in private infrastructure, like older ERP systems

• Maximum control and customisation, but with higher maintenance costs

This means you've got options - choose the model that fits your business needs.

SAP S/4HANA user interface (Fiori)

The SAP Fiori interface has transformed the way users interact with the system.

It gives you:

• Role-based dashboards, so you can see what you need to see

• Simple, intuitive applications that are a breeze to use

• Access across desktop, web, and mobile devices, so you can work anywhere

• Real-time data views, so you can stay up to date

This all adds up to:

• A better user experience

• Improved productivity, because you can get on with the day job

• Faster system adoption, so you can get up and running quickly

What you get with SAP S/4HANA

S/4HANA includes a whole range of capabilities to help you run your business.

• Finance (simple finance) - real-time financial reporting, general ledger, financial accounting, and financial planning

• Material Management (MM) - procurement and inventory management

• Sales and Distribution (SD) - order management and billing

• Production Planning (PP) - manufacturing processes that automate tasks and support complex processes

• Extended Warehouse Management (EWM) - warehouse operations with tools for transportation management and warehousing

• Asset Management - maintenance and asset lifecycle for business assets

• Supply Chain Management - planning and logistics integration across over 100 business processes in supply chain management

In finance, the platform gives you real-time insights and predictive analysis to help you make faster decisions. These modules provide end-to-end visibility across supply chain operations, and support over 100 business processes across functions.

The business partner concept in SAP S/4HANA

S/4HANA introduces the Business Partner model, which is a game-changer for how you manage customer and vendor relationships.

Instead of separate customer and vendor records:

• You use a single business partner to manage all relationships

This simplifies data management and integration across all processes.

Migrating to SAP S/4HANA

Migration to S/4HANA is a key part of SAP transformation - and it's all about succession planning, because by 2027 SAP will stop supporting SAP ECC & other old ERP systems completely.

Thing is, many IT landscapes are a right old mess, so a lot of big companies start by sorting that out first, with a landscape transformation, before moving on to the migration itself. Depending on the scope, migration can easily take up to 2 years. Of the main approaches, 44% of companies are all about the brownfield route, while 14% prefer greenfield.

It doesn't really matter which path you take at the end of the day - you'll still probably need to redesign processes, get some change management in place and retrain the team.

Common migration approaches

Greenfield

• Starting from scratch with a completely new system

Brownfield

• Doing a system conversion - updating the existing one

Hybrid

• A bit of both - selective transformation

SAP S/4HANA Migration Steps

• System assessment

• Get all the data in order, and prepare it for migration

• Decide on the best migration approach

• Do the system conversion OR build it from scratch

• Test and validate everything

• Go-live

• Optimise for the best results

Having a solid migration strategy is key to avoiding any major pitfalls - it will help you reduce risks, get better results and get the system up and running more smoothly.

SAP S/4HANA implementation

Implementing S/4HANA is no quick fix - you're going to need to put in some serious time and effort. Typically, it can take anywhere from six months to over a year, depending on how complicated it is and how many features you're trying to roll out. Sometimes, you'll need to do some custom software development as well to make sure it all fits together smoothly.

Key implementation steps

• Define what you need the system to do

• Work out the system architecture

• Configure the processes to your advantage

• Move all the data across

• Test that the system all works as it should

• Get the users up to speed with change management and retraining

• Get the system deployed and supported

A typical implementation project plan would include a timeline, resources, risks and mitigation - as well as all the key milestones.

SAP Activate methodology is often used as a guide, and some organisations use it alongside industry solutions accelerators in design & configuration.
