Learn to configure SAP MM by doing, not watching.
SAP is the business software many companies use for their purchasing, stock, production and accounting. SAP MM (Materials Management) is the part that handles purchasing and stock. To configure is to set the software up so that it follows the company's rules: who approves what, which ledger account each purchase lands on. A specialization is a full training course on one area of SAP.
Here, you configure Glass+, a fictional company, end to end, from the approval of purchases to the complete purchasing chain. Most of it happens in a simulator, in your browser: this is not a real SAP. You don't follow a course: you run missions where every decision has consequences. A hands-on task is something you do on screen in the simulator: you will do 69 of them.
Know, do, prove.
The specialization comes in three parts.
Understand the purchasing module
Every notion is explained before you put it into practice, with 60 reference sheets (explanation pages) and 26 diagrams to consult whenever you want. You don't need to know SAP before you start.
Do the job
69 hands-on tasks in the simulator, where a wrong configuration blocks the next step. Like on a real project.
Prepare for the certification
The specialization covers the topics of the official exam syllabus of the SAP Sourcing & Procurement certification (C_TS452). Some topics are only explained on a sheet. A final review adds 56 practice questions we wrote ourselves. The exam itself is not included in the price: you take it separately, through SAP.
Watching SAP does not teach you to configure it.
You may have taken courses, watched demos, read the documentation, or you may not have seen SAP yet. Either way, faced with a real need (setting up an approval for purchases, creating supplier records, wiring up accounting), you wouldn't know where to start.
Watching is not knowing how
Following a demo is easy. When it is your turn, with consequences if you get it wrong, it is another story.
Each topic is taught on its own, never the thread between them
Master data (materials, suppliers, prices), purchase approval, ledger accounts, document numbering. Nobody shows you how they fit together in a project.
Using SAP is not configuring it
You may know how to create an order as a user. But designing the purchase approval behind it, deciding who approves what and above which amount, 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 the live system to practice. So you never get the chance to configure, get it wrong, and fix it in a system that reacts.
An empty SAP teaches nothing
Even with trial access (a sandbox), it is an empty shell: no business context, no stakes, no data that connects. 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 working 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 delivered file, and you come out able to explain and redo the purchasing processes from end to end.
We don't explain MM to you. We have you do it.
Here, you play a junior consultant that Glass+, a fictional company, brings in for its procurement project. You get assignments the way a client would hand them out, the simulator reacts to what you configure, and you walk away with a file to show.
Several purchases went out with no approval at all. Every purchase requisition above €10,000 must go through purchasing, then finance. Can you set that up for me?
You get assignments from a client
Not a quiz, not an abstract exercise. Marta, the purchasing key user in Valencia (she uses SAP for purchasing every day), hands you an assignment the way a client would: set up approval for purchase requisitions, the internal requests that come before an order. It is on you to work out the problem, design the solution and configure it.
The simulator reacts to what you do
You set the release strategy (the approval rule: above a threshold, the requisition must be approved), and a €13,800 purchase requisition no longer goes through on its own: it is created as "blocked, pending approval". Cause, effect, on screen. Not a video.
You walk away with a file to show
By the end, you hold the documents a consultant hands to a client. In an interview, you do not recite theory: you show what you configured in the simulation.
Six consultant skills, not theory.
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: who approves what, above which amount.
Create procurement master data
You will know how to create a material master (an item's record), a supplier, an info record (the price agreed with a supplier) and a source list (the suppliers allowed for a material), all filled in correctly.
Set up a document type and its numbering
You will know how to create a purchasing document type (for example for capital purchases) with its own number range (a reserved series of numbers), so you can tell at a glance which circuit a document comes from.
Wire procurement to accounting
You will know how to make each goods receipt land on the right ledger account, through automatic account determination (code OBYC).
Test and fix as you would on a project
You will know how to test your configuration on a concrete case, see the error on screen, fix it and check again.
Produce consultant deliverables
You will know how to write a functional specification (the need and the chosen solution), a configuration specification (the exact settings), 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. You can start from zero: you don't need to know SAP, although a few notions make it easier to get going.
This specialization is for you if…
- You want to actually know how to configure SAP MM, not just talk about it.
- You are retraining toward SAP consulting and want practice, not yet another video.
- You are a junior on MM and want to consolidate your configuration skills on a complete case.
- You have taken courses or watched demos, or you have not seen SAP yet, but you have 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 only want to learn to use SAP for your own purchasing: here you configure, which is the consultant's job.
- You want a coach beside you throughout your career change: look instead at Beyond the Horizon (our coached path, which includes this specialization).
- You are looking for a course to watch passively: here you spend your time working hands-on in the simulator and producing deliverables.
- You would rather work on accounting or sales: see our SAP FI (finance) and SAP SD (sales) specializations. For another module, such as production, see the Expert Training Center.
Twelve missions, from the basics to the full job.
One running thread, the company Glass+: from its first purchase requisition to its complete purchasing chain. Twelve missions in four stages (blocks 1 to 3 and the final), followed by a 13th episode, the review. You build a consultant's habits along the way. SAP calls each data-entry screen a "transaction": you use 24 of them.
The foundations
You set up the approval of purchases above €10,000, you create the master data for silica sand and a document type with its number range, then the accounts that link purchasing to accounting. You finish by handing over your work: a user guide, then a final audit where you replay the whole chain to check that your configuration holds.
The complete purchasing cycle
You run the cycle on the first silica sand delivery to the Valencia warehouse: order, receipt, then a €10,200 invoice (120 metric tons at €85 per metric ton). It matches the receipt, but you park it (save it without posting it): at Glass+, management accounting must approve the first invoice from a new supplier. After that approval, you post the invoice, meaning you record it in the accounts. An incident follows, on another order: an invoice comes out blocked for payment, and you trace it back to its cause, a quantity received lower than the quantity invoiced.
Advanced processes
You set up a tolerance group (the accepted margin of difference) for small invoice differences in subcontracting, a 200-metric-ton soda ash agreement delivered as you place call-off orders, and automatic replenishment, then you get purchase orders approved from an approval inbox.
The dress rehearsal
A dress rehearsal on a brand-new material, dolomite. You create the master data, the contract, the approved supplier list and the replenishment threshold. You run the planning, get the order approved, receive the goods, then verify the €17,250 invoice.
The review before the certification
After the dress rehearsal, you go back over the 11 syllabus topics one by one, with Glass+ figures: a short reminder, the classic traps, then questions. The 56 practice questions are ones we wrote ourselves: none of them comes from the exam. The review flags the subjects the simulator does not let you practice: they are explained on a sheet, and to practice them you need a real SAP system, which the training does not provide. You finish outside the simulator: a review sheet of two pages at most, and your mission file, which holds the 15 documents.
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 create a purchase requisition and test your release strategy, and produce your consultant deliverables. The path covers twelve missions and a review episode, up to the main topics of the certification program.
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 play a junior MM consultant at Glass+, and Marta hands you assignments the way a client would. Each time, it is up to you to understand, design, configure and test.
Your mistakes show on screen
A badly set release strategy lets a purchase requisition above €10,000 through, and you see it on screen. You fix it and check again.
You deliver a mission file
From your second mission on, each episode ends with one or more documents you write yourself, outside the simulator: the kind a consultant hands to a client. Each one has its own check question, so you can verify your own work.

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.
What our students say about Key User Training.
These reviews are about our training courses in general, built on the same principle as this specialization: simulations based on virtual companies.
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 specialization that covers the topics of the official exam syllabus of the SAP Sourcing & Procurement certification (exam not included)
In 2026, SAP changed its certifications. No more multiple-choice questions: the Sourcing & Procurement certification (reference C_TS452) is now a performance-based exam, with practical scenarios that depend on one another. You face concrete cases where a wrong decision makes the rest fail. The exam is taken through SAP: it is not included in the specialization.
This specialization covers the topics of the official exam syllabus: every topic has its own reference sheet, most are practiced in the simulator, and some are only explained on a sheet. You practice the main topics inside a coherent simulated company, from the first configuration to a dress rehearsal that chains everything end to end. Here is what you do in the simulator:
- Master data and configuration (material, supplier, info record, source list, document types, number ranges)
- The complete purchasing cycle, from the purchase order to goods receipt (MIGO) and invoice verification (MIRO), with the three-way match and parking the invoice
- Release strategy, in its classic version and its modern version (flexible workflow, in Fiori, SAP's newer interface)
- Automatic account determination (OBYC) and the link between purchasing and accounting
- Subcontracting, from providing the components to receiving the finished product
- Outline agreements and call-off orders
- Material requirements planning (MRP), from the item's threshold to automatic replenishment
You also leave with a portfolio of consultant deliverables (specifications, test plan, user guide, procedure sheets, mission file) that the exam does not test, but that the job demands.
A 13th review episode then goes back over every topic of the syllabus, including the ones the simulator does not let you practice: 56 practice questions we wrote ourselves (43 multiple-choice to lock in the knowledge, 13 "predict" questions where you say what the system will answer before seeing it). None of them comes from the exam.
Before the exam, you will already have run most of these processes in our simulator. The exam itself is taken in a real SAP system: our screens are our own creation, not SAP's. You will find the same screen logic and the same transactions there (ME21N, MIGO…); only the look changes.
You don't leave with a certificate for watching videos. You leave with documents you can show.
From your second mission on, every episode has you produce consultant documents: functional specification (the need and the solution), configuration specification (the exact settings), test plan, configuration notes (what you set up and fixed, incidents included), user guide, procedure sheets (step-by-step guides that let a colleague redo a process without you), up to the review sheet. All of it goes into your mission file: 15 documents in total, written outside the simulator. Each one has its own check question, so you can verify your own work. You can then show them to a recruiter.
12 missions and a review, lifetime access, updates included.
One-time payment, immediate access, 14-day guarantee. You progress mission by mission, at your own 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 the release strategy to master data, from the complete purchasing cycle to advanced processes, all the way to the review and the deliverables file. Most of it happens in the simulator, in your browser: this is not a real SAP, and there is nothing to install.
14-day money-back 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 fictional company we built for you: a glass factory that has just opened a new site in Valencia and hands you the configuration of its procurement. It is the setting for the whole specialization.
Do I need SAP access to follow this?
No. There is nothing to install: most of it happens in the simulator, from your browser. The training does not provide access to a real SAP system.
I am a beginner. Is it doable?
Yes. You don't need to know SAP: the simulation explains each notion when it is needed and guides you step by step, then lets you handle the assignments Marta gives you and the final audit on your own. A few SAP notions make it easier to get going, but they are not required.
How long does it take?
It mostly depends on how comfortable you already are with SAP, so we do not give a duration. You go mission by mission, at your own pace, you can stop and resume whenever you want, and you have lifetime access.
And if I get stuck, with no coaching?
The simulation guides you step by step, with two or three hints on each hands-on task. 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 and a review episode inside a simulated company. You carry out 69 hands-on tasks (things to do on screen) in the simulator, using 24 screens that SAP calls "transactions". You lean on 60 reference sheets and 26 diagrams, and you write 15 consultant documents outside the simulator. By the end, you have done the work, not just watched someone do it.
What if it is not right for me?
You have a 14-day money-back 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-based 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, SAP's current version. The certification, for its part, targets one specific edition, S/4HANA Cloud Private Edition. This is not a real SAP: our screens are our own creation. The notions you work on (release strategy, OBYC, master data) 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 carries over from one mission to the next and deliverables to produce. That is the difference between watching and knowing how.
Does this specialization prepare me for the SAP certification?
It covers the topics of the official exam syllabus of the Sourcing & Procurement certification (C_TS452). Some topics are only explained on a sheet, and the simulator flags the ones it does not let you practice. A final review adds 56 practice questions (43 multiple-choice, 13 "predict" questions) that do not come from the exam. The exam itself is not included: you take it separately, through SAP.
Is the certification included?
No, the exam is taken directly through SAP and its price is not part of the specialization.
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 questions to a performance-based assessment: practical scenarios that depend on one another.
I'm aiming for freelance work or a salaried role. Does it help either way?
Yes. The case you run and the documents you produce resemble what a junior MM consultant is expected to do, whether you are after a salaried role or freelance projects.
You will not watch SAP MM. You will do it.
Take the role at Glass+, run the case from need to delivered file, and come out with documents to show.
