Learn SAP S/4HANA from scratch — a ten-station path in order

Every other path on this site opens on “where do I start?”. This one opens on a harder question: what do I start with inside the system at all?

Because the sentence that belongs in the first line rather than the last is this: nobody is an “SAP consultant.” People are FI consultants, or MM, or SD, or PP. A learner who decides “I will learn SAP” without naming a module spends a year moving between screens that produce no single output, then discovers that every job advert in front of them names a module explicitly.

What this path is, and what it is not

This is not a substitute for official SAP training, and it does not pretend to hand you access to a system you do not have. The product has no downloadable copy you run on your own machine the way you do with other systems on this site, and any path that ignores that fact is selling you a fiction by its second station.

This path does three things: it settles the module decision before you lose months to it, it builds the conceptual understanding that makes your first day in front of a real system — at an employer or an implementation partner — a productive day rather than a lost one, and it tells you plainly where what you can do alone runs out.

If your question is instead “should I choose S/4HANA for my company?”, that is an entirely different question, answered in the SAP S/4HANA guide — where the price is unpublished, the licence is the smaller half of the invoice, and seven points are named where the project stumbles.

The ten stations

#	Station	What you walk away holding
1	Where to start	A written decision naming one module, and why
2	The training environment	A named route to access, with its cost — not a wish
3	Company and master data	The organisational structure, the business partner, and the material master
4	The purchase cycle	Three-way matching from requisition to payment, and its entry
5	The sales cycle	Order to collection, and where documents generate themselves
6	Inventory and costing	Standard cost against moving average, with the difference measured
7	Accounting and the close	The universal journal, and why FI-to-CO reconciliation ended
8	Localisation and e-invoicing	The vendor’s own product, separately licensed — and the difference that makes
9	Customisation and extension	Configuration, then extension, then code — and each deployment shape’s ceiling
10	Certification and a first job	An exam with a name and a number, and a portfolio you present in an interview

Three structural facts that govern the whole path

Before station one, three things. Miss them and the learning stays a memorisation of screen names.

One: a single universal journal. In earlier generations financial accounting (FI) and management accounting (CO) wrote into separate tables, so part of every month-end close was reconciling the two. In S/4HANA they merged into one line-item table. The effect on a learner is not technical: it means the question “why does the management report differ from the statutory statements?” — the commonest question in a closing room — lost its subject matter. Understand that and you understand why the product was built at all.

Two: one business partner, not two records. A customer used to be one record and a vendor another, so a company that buys from its own customer carried it twice under two numbers. Now a single record carries the roles. That difference shows up in master data at station three, and again at station eight when e-invoicing asks for one tax number rather than two.

Three: one database, by name. S/4HANA runs on SAP HANA alone — not Oracle, not SQL Server. So anyone migrating from an earlier generation is not merely changing a system; they are changing the database underneath it in the same project. That is one of the clearest reasons the project is heavier than the presentation suggests.

The honest time, and why it is longer here

The realistic estimate is longer than its equivalent on every other path on this site, for one explicit reason: part of your time will not pass in front of the system, because you most likely do not have one.

• 25 hours to settle your module and read the system map without drowning in acronyms.
• 70 hours to explain a full cycle in your module, with its documents and its accounting effect.
• 120 to 180 hours to reach the standard where you pass the module exam.

And something matters more than the number: this is the only path on the site that may require a financial decision at its second station. Access to a real training system has a limited set of routes, some paid, some running through an employer, and all of them are discussed there without decoration.

Three rules that govern this path

One: one module first, then breadth. A consultant who knows FI deeply and MM shallowly is more useful than one who knows six equally and shallowly. Breadth comes from projects, not from courses.

Two: learn the concept before the screen. Because the screen may not be available to you today, and because Fiori changed the shape of the interface from what most older videos on the internet show. Memorise an old transaction code and you have memorised something that moves; understand what a document does to the ledgers and you carry knowledge that holds.

Three: assume the deployment shape decides what you can do. There are three shapes, and they are not three grades of one thing: on premise, private cloud, and public cloud. The last is upgraded on a mandatory twice-yearly cycle, and that alone decides what may be customised. The detail is at station nine, and anyone who conflates the three makes promises they cannot keep.

What waits at the end

The certification here is not one certification for the system but one per module. The example read from the official certification page on 5 September 2026 shows its shape: the financial accounting certification carries the code C_TS4FI, runs 180 minutes, passes at 60 per cent, and is available in English only. A recertification programme with periodic assessments attaches to it.

Three things in that paragraph deserve a second reading. That the exam is English only makes reading English an entry condition rather than an extra skill. That certification is per module means the station-one decision is also the certification decision. That accreditation is renewed means this is not a paper hung once but a continuing commitment.

Above all, this market has a property no other shares: mainstream maintenance for the previous generation ends on 31 December 2027, with paid extension to 31 December 2030. The meaning for a learner is direct: a migration wave with a known date, and demand for people who know both generations.

Start here

Station one opens no screen at all. It settles one question — which module — against six written criteria, because everything after it changes when that answer changes.
