Week 1 — Enterprise structure and master data
Set up your own slice of the org structure so nothing you do collides with other learners, then create the master data every later step depends on.
- Define plant, storage location and purchasing organisation
- Assign the org units and understand each assignment
- Create material masters across views (MM01)
- Create vendor master as a Business Partner on S/4HANA (BP)
- Maintain purchasing info records (ME11)

Week 2 — Procure to pay, end to end
Run the full cycle at least three times with different scenarios until the document flow is second nature.
- Purchase requisition (ME51N) and release strategy
- Purchase order (ME21N) with and without a requisition
- Goods receipt (MIGO) and the accounting document behind it
- Invoice verification (MIRO) and the three-way match
- Payment run visibility in FI

Week 3 — Inventory and special processes
This is the week that separates candidates who have read about MM from candidates who have used it.
- Movement types: 101, 122, 261, 311, 561 — and why each exists
- Stock transfer orders between plants
- Subcontracting and consignment cycles
- Physical inventory count and difference posting

Week 4 — Integration and configuration
MM interviews are really integration interviews. Spend the last week where MM meets FI, SD and PP.
- Automatic account determination (OBYC) — the topic most asked
- Split valuation and valuation classes
- MM–SD intercompany stock transfer
- MRP basics and how PP consumes your material master
Key takeaways
- Finish the P2P cycle three times before moving on
- OBYC is the single most-asked MM configuration topic
- Practise on your own plant so your data stays clean
- One hour a day for four weeks beats one weekend of cramming
