Become operational in SAP MM by doing, not watching.
A simulation where you configure a real system end to end: from the first piece of master data to the complete purchasing process. You don't follow a course, you run missions inside a simulated company where every decision has consequences.
Know, do, prove.
A complete training, in three parts.
Understand the module
Every concept is explained before you put it into practice, with 45 reference sheets to consult whenever you want.
Do the job
66 hands-on tasks inside a simulated company, where a wrong configuration blocks the next step. Exactly like a real project.
Prove your skill
You cover the scope of the SAP Sourcing & Procurement certification (C_TS452), in the hands-on format of the new generation of exams.
You recognize the SAP MM screens. You wouldn't know how to configure them yourself.
That's normal. You may have taken courses, watched demos, read the documentation. But faced with a real need, setting up a purchase approval, creating a vendor's data, wiring up accounting, you wouldn't know where to start.
Watching is not knowing how
You recognize the transactions, you follow a demo just fine. But when it is your turn, with consequences when you get it wrong, that is another story.
The basics are everywhere, the thread nowhere
Master data, release strategy, OBYC, number ranges. Each topic exists somewhere, but no one shows you how they connect in a real project.
Using SAP is not configuring it
You may know how to create an order as a user. But designing the release strategy behind it, deciding the characteristics and the levels, that is the consultant's job. No one lets you do it.
You are never allowed to test for real
In a real company you do not touch production to practice. So you never get the chance to configure, get it wrong, and fix it on a system that reacts.
An empty instance teaches nothing
Even with a sandbox, it is an empty shell: no business context, no stakes, no data that answers back. You click without ever deciding anything.
In an interview, you have nothing to show
You are asked what you have already configured. Without a concrete case run end to end, you answer in theory. A real file changes the conversation.
This specialization exists for exactly that.
You don't watch someone configure. You take the role, you run the case from need to handover, and you come out able to hold the assignment.
We don't explain MM to you. We have you do it.
Here, a company hires you and hands you its procurement project. You get real tickets, the system reacts to what you configure, and you walk away with a file to show.
€12,000 orders are going out with no control whatsoever. Before the Valencia go-live, I need a purchase approval in place. Can you configure that for me?
You are dropped into real tickets
No quiz, no abstract exercise. Marta, your procurement manager, sends you a real business problem. It is on you to frame it, design it, configure it.
The system reacts to what you do
You set the release strategy, and the same order goes from "slipped through on its own" to "blocked, pending approval". Cause, effect, on screen. Not a video.
You walk away with a file to show
By the end, you hold a real consultant's deliverables. In an interview, you do not recite theory: you show what you actually configured.
Six consultant moves, not slides.
By the end you will not have watched MM. You will have done it: a complete procurement case, from business need to delivered file.
Configure a release strategy
You will know how to design and configure a purchase approval end to end, including characteristics, class, groups and release codes.
Create procurement master data
You will know how to create a clean material master, a vendor as a Business Partner, an info record and a source list.
Frame documents and numbering
You will know how to set up the purchasing document types and number ranges suited to a site.
Wire procurement to accounting
You will know how to link purchasing movements to the right accounts through automatic determination (OBYC).
Test and fix like in a project
You will know how to test your configuration on a real case, see the error on screen, fix it and re-test.
Produce consultant deliverables
You will know how to write a functional spec, a configuration spec, a test plan and a user guide.
Who it is for, and who it is not.
The specialization is self-paced, guided step by step by the simulation. Accessible if you are starting out, more comfortable if you already have some notions.
This specialization is for you if…
- You want to actually know how to do SAP MM, not just talk about it.
- You are retraining toward SAP consulting and want real practice, not yet another video.
- You are a junior on MM and want to consolidate your configuration on a complete case.
- You have taken courses or watched demos, but never run a case from end to end.
- You want to come out with a concrete file to show in interviews.
This specialization is not for you if…
- You are already an experienced MM consultant, the level is too junior.
- You are looking for a full retraining path with human coaching, look instead at Beyond the Horizon (which includes this specialization).
- You are looking for a course to watch passively: here you spend your time working hands-on in the system and producing deliverables.
- You want another SAP module such as FI, SD or PP, look instead at the Expert Training Center.
Twelve missions, from the basics to the full job.
One single thread, the company Glass+: from its first piece of master data to its complete purchasing process. Twelve missions grouped into four stages, where you quickly build a consultant's reflexes.
The basics
You create procurement master data, then set up document types and number ranges. The foundations everything else rests on.
The complete purchasing cycle
You run the whole cycle, from the requisition to the purchase order, to goods receipt and invoice verification. You run the three-way match, the heart of the purchasing job.
Approval and accounting
You build a release strategy, both classic and flexible workflow Fiori. You configure account determination (OBYC) and you understand the MM-FI bridge.
Advanced processes
Subcontracting, outline agreements, material requirements planning (MRP). The level an employer really tests for a consultant role.
The final mission
A dress rehearsal that chains everything together, from configuration to the P2P close, like an end-to-end project.
You just read what you'll do. Now watch it.
Animated product tour of Key User Training's SAP MM Glass+ simulation: a character hands you a mission, you configure and test a release strategy, produce your consultant deliverables, and the path covers twelve missions.
A preview. In the simulation, you run every mission yourself.
Three choices you will not find in a video.
You do it, you do not watch
You are not following a course. You take a junior MM consultant role at Glass+, and Marta sends you real problems. Each time, it is up to you to understand, design, configure and test.
Your data stays
A badly set release strategy lets a 12,000 € order through, and you see it on screen. You fix it, you re-test. You remember a transaction when you have lived its consequences.
You deliver a file
At the end of each mission you produce a real consultant's deliverables. You do not leave with a watch-time certificate, you leave with documents you can show.

SAP consultant and trainer · co-founder of Key User Training
Michael has spent several years supporting career changers, students and junior consultants who want to build real SAP skills. Co-founder of Key User Training with Pierre Balbinot, he built the Glass+ simulation on a simple principle: you only teach a topic well once you have lived it, failed at it, or fixed it on an assignment.
Verifiable feedback, not slogans.
The reviews below are about the Key User Training way of doing things: simulations based on virtual companies, like the MM specialization.
The simulation is what unlocked it for me
I tried courses on Udemy, explored the SAP Learning modules, and something was always missing to become a junior SAP consultant. The simulations and module configurations based on virtual companies are really what sets Key User Training apart. Every euro spent is truly worth it.
It is like you are on SAP
I already worked as a SAP user, so I did this course to refresh my knowledge. The interactive way of the course is the best, it is like you are on SAP. It is dynamic, with a base of an enterprise case, so it helps you understand and think in those terms. I will always recommend this course.
Structured, progressive, concrete
Key User trainings take you by the hand. They are structured, progressive and combine theory with practice through demonstrations based on concrete situations encountered every day in companies.
Tailor-made and a perfect fit
Key User Training is to SAP training what a good tailor is to the textile industry: hand-stitched, elegant, and for me it was tailor-made and fit like a glove.
A leap forward in my SAP practice
Already a SAP user across several modules for a few years, the Key User Training team really helped me take a leap forward and genuinely moved my SAP practice ahead. The professionalism and availability of the trainers are their main strengths.
Five trainings, same clear structure
Five trainings already with Key User Training. It is really the same structure whatever the course: theory and practice through concrete situations. The big plus is the responsiveness, the trainers getting back to you on questions or difficulties.
A course that covers the entire scope of the SAP Sourcing & Procurement certification
In 2026, SAP changed its certifications. No more multiple-choice: the Sourcing & Procurement certification (reference C_TS452, S/4HANA Cloud Private Edition) is now a performance-based exam, built on practical, interdependent scenarios (open book). You face concrete cases where a wrong decision makes the rest fail.
That is exactly what this course trains you for. You don't watch, you do. And you don't just do one piece: you cover the seven areas of the exam scope, inside a coherent simulated company, from the first configuration all the way to a final mission that chains everything end to end:
- Master data and configuration (material, vendor, info record, source list, document types, number ranges)
- The complete purchasing cycle, from purchase requisition to goods receipt (MIGO) and invoice verification (MIRO), with the three-way match
- Release strategy, both classic AND flexible workflow Fiori (the new generation)
- Account determination (OBYC) and the MM-FI bridge
- Subcontracting, from providing the components to receiving the finished product
- Outline agreements and call-off orders
- Material requirements planning (MRP), from the reorder point to automatic replenishment
And you don't just leave competent: you leave with a portfolio of consultant deliverables (specifications, test plan, handover file) that the exam does not even test, but that the field demands. The day you sit at the SAP system for the exam, you have already run every process, and you know why.
You don't leave with a watch-only certificate. You leave with proof.
In every mission, you produce the deliverables a client pays a consultant for: functional specifications, configuration specifications, test plans, configuration notes, a handover file. 12 deliverables in total, the kind you can show a recruiter on interview day. Free content never produces that.
12 missions, lifetime access, updates included.
One-time payment, immediate access, 14-day guarantee. You progress mission by mission, at your pace, and come back whenever you want.
SAP MM Specialization
The work of an SAP procurement consultant, inside a simulated company, from configuration to deliverables.
You progress through missions at Glass+, from master data to the complete purchasing cycle, from the release strategy to advanced processes, all the way to the deliverables file. Everything happens inside the simulation, with no SAP to install.
14-day satisfied-or-refunded guarantee
If the specialization is not right for you, a simple email within 14 days is enough. Full refund, no justification required.
The questions we get before people start.
What is Glass+?
Glass+ is the company we built for you: a glass factory opening a new site in Valencia that hands you the configuration of its procurement. It is the setting for the whole specialization. You need nothing else, no other course and no prior knowledge of it, everything is inside the simulation.
Do I need SAP access to follow this?
No. Everything happens inside the simulation, from your browser. No installation, no SAP system to set up on your side.
I am a beginner. Is it doable?
Yes. The simulation explains each notion when it is needed and guides you step by step. A few SAP notions make the progression more comfortable, but they are not required.
How long does it take?
Plan for around 20 hours to do everything properly: read, configure and produce the deliverables. It is real practice, not a two-hour video. You go at your own pace, access is for life.
And if I get stuck, with no coaching?
The simulation guides you step by step, with hints at each stage. If you want human support and a complete path, that is what Beyond the Horizon offers, and the MM specialization is included in it.
How long do I have access?
Lifetime access to the specialization content, updates included. You come back to it as much as you need. Access covers the learning content and the simulation, not an SAP system.
What will I actually do?
You run 12 missions inside a simulated company. You perform 66 hands-on tasks in the system, you lean on 45 reference sheets, and you produce 12 consultant deliverables. By the end, you have done the job, not just watched someone do it.
What if it is not right for me?
You have a 14-day satisfied-or-refunded guarantee. A simple email is enough, no justification required, and we refund you in full.
Can I get an invoice for my company?
Yes. Key User Training is a Luxembourg training organization, we issue an invoice in your company's name after payment. For any specific mention, contact us before purchasing.
Which SAP version is this on?
The simulation reflects MM configuration on SAP S/4HANA. The notions you work on, release strategy, OBYC, master data, are structural and stay valid from one version to the next.
How is this different from a regular online course?
A course shows you someone clicking. Here you take the role and configure it yourself inside a simulated company, with data that persists and deliverables to produce. That is the difference between watching and knowing how.
Does this course prepare me for the SAP certification?
It has you carry out, in an interactive simulation, the seven areas of the Sourcing & Procurement certification scope (C_TS452): master data, the complete purchasing cycle up to MIGO and MIRO, classic and flexible-workflow release, OBYC, subcontracting, contracts, MRP, up to a final integrative mission. You build the real skill the exam tests.
Is the certification included?
No, the exam is taken directly with SAP. The course makes you competent to approach it on familiar ground.
Which certification is targeted?
SAP Certified Associate: SAP S/4HANA Cloud Private Edition, Sourcing & Procurement (reference C_TS452).
Has the exam format changed?
Yes. SAP moved from multiple-choice to a performance-based assessment: practical, interdependent scenarios in open-book conditions. A simulation-based course is the best training for that format.
I am aiming for freelance or a salaried role, does it help either way?
Yes. The case you run and the deliverables you produce are exactly what an MM consultant is expected to do on an assignment, whether you are after a salaried role or freelance missions.
You will not watch SAP MM. You will do it.
Take the role at Glass+, run the case from need to handover, and come out with deliverables to show.
