🧩 Interactive Tools — Play with SAP MM

Reading explains it; doing makes it stick. These hands-on tools let you click real SAP movements, watch backend tables fill, explore master-data views, map the org structure, and drill for retention — all in your browser, no SAP login needed. Each pairs with a topic page so you can read it, then try it.

💡 These are learning simulators — they mimic SAP behaviour to build intuition (which posting creates an FI document, what a movement type does, what blocks a transaction). They don't connect to a real system; for the real T-codes, follow the Setup Guide and Scenarios.
🏦 Postings & Accounting
🧮

Posting Simulator (T-accounts)

Click goods receipts, issues, invoices, payments — watch the T-accounts balance live and see which postings create an FI document and which don't (with the OBYC keys).

Plant vs Storage Location

Prove the core rule: value lives at plant level, quantity at storage-location level — and see why a 311 transfer posts no FI document while a 101/261 does.

Open tool → pairs with Storage Locations
🗄️

P2P Database Explorer

Run a full Procure-to-Pay cycle and watch all the backend tables (EKKO, MSEG, BKPF, BSIK…) fill row-by-row. Toggle centralized vs decentralized and watch master-data rows multiply.

🏗️ Org Structure & Master Data
🗺️

Org-Structure Map

A clickable map of the whole enterprise structure (Client → Company Code → Plant → Storage Location, plus Purchasing Orgs & Groups). Click any node for its dossier, or run a "follow a PO / GR / Invoice" walkthrough.

🧭

Purchasing-Org Design Advisor

Answer 5 questions and get a centralized / decentralized / hybrid purchasing recommendation, with a 6-tab side-by-side comparison (master data, reporting, approvals, books, vendor, operations).

Open tool → pairs with Purchasing Org
📑

Material Master Views Explorer

Pick a material type (ROH/HALB/FERT…) and see exactly which of the ~28 views are required vs relevant, then drill into every field's mandatory flag, example value and purpose.

Open tool → pairs with Material Master
🧱

Master-Data Extension Demo

Extend a vendor or material level-by-level (LFA1→LFB1→LFM1; MARA→MARC→MARD), watch the DB rows appear, and test which transactions stay blocked until you extend.

Open tool → pairs with Material Master / BP setup
🎯 Practice & Retention
🃏

Flashcards (spaced repetition)

Drill 50 org-structure & T-code cards with a real SM-2 spaced-repetition engine that schedules each review by how well you knew it. Add your own cards; progress saves in your browser.
