Scenario 18 — QM Integration (GR into Inspection Stock + Usage Decision)
📊 Business Case
With QM active in procurement, a goods receipt does not drop straight into usable stock. It lands in quality inspection stock, an inspection lot is created, and the material is locked until QC records results and makes a usage decision. That decision is the quality gate that stops out-of-spec material — bad iron ore, expired chemicals, off-grade steel — from ever reaching production.
🕐 When to use it
Whenever incoming material must pass inspection before use — raw materials with spec limits (sulfur %, purity), regulated goods, or any supplier whose quality you must verify on receipt.
❓ Why it matters
It's a quality gate in the P2P flow. Inspection stock is not freely usable, so defective material can't be issued to production by mistake. A failed lot is rejected back to the vendor instead of becoming a costly production failure.
👤 Who triggers it
Stores post the GR (which auto-creates the inspection lot); QC records results (QE51N) and makes the usage decision (QA11); the buyer handles rejected lots returning to the vendor.
🔁 The key distinction
Without QM, GR mvt 101 goes straight to unrestricted stock. With QM, the same 101 goes to quality inspection stock — usable only after a usage decision releases it (321) or rejects it (122).
💰 Financial Impact — The Easy-Money Example
PakSteel receives 50 TO of iron ore on a PO. With QM the stock is held in quality inspection until QC tests the sulfur content — it is not available for production and is not part of usable inventory until released:
The big idea: blocked / inspection stock is not available for use until the usage decision releases it. That gap between "received" and "released" is the quality gate — defective material is caught and rejected before it can be issued, instead of being discovered mid-production at far greater cost.
🇵🇰 The Business Story
🎯 What you'll learn
- Activate QM view in material (MM02 → QM view → Inspection Setup: Type 01 GR Inspection)
- GR with QM auto-creates Inspection Lot + stock moves to "Quality Inspection" status
- Inspector enters results in QE51N / QA32
- Usage Decision (QA11) — Accept → mvt 321 (Q→unrestricted); Reject → mvt 122 (return)
- Material can't be used until usage decision made
- QM activation is typically done by QM consultant — basic activation in SPRO → QM → Basic Settings → Activate QM in MM
- Material master must have QM view with Inspection Type 01 (GR Inspection) active
- 🪂 Alternative: Skip this scenario if QM not available; works without QM via standard GR mvt 101 to unrestricted stock

🔧 Step-by-Step
⚙️ Setup (high level)
18.1 — Activate QM Inspection on Material
- MM02 · RM-IRON-01 · Inspection Setup view
- Inspection Type:
01(Goods Receipt for Purchase Order) - Active ✓ · 100% inspection · Save
🔄 Test
18.2 — GR creates Inspection Lot · MIGO
- MIGO · GR · mvt 101 · post
- Material shows in "Quality Inspection" stock (not Unrestricted)
- Inspection Lot # auto-created
18.3 — Record Results · QE51N
Enter measurement values (sulfur %, density, etc.) against the inspection lot.
18.4 — Usage Decision · QA11
- QA11 · Inspection Lot #
- Usage Decision: Accept → Qty to Unrestricted = 50 TO · save → mvt 321
- OR: Reject → Qty to Blocked/Return = 50 TO → mvt 122 auto-posted
✅ Verification
- MMBE → see "Quality Inspection" + "Unrestricted" + "Blocked" columns change as you decide
- QA32 → list of open inspection lots
🎓 Interview-Ready Answers
Q: With QM active, where does GR movement 101 post the stock?
Into quality inspection stock, not unrestricted. The 101 still posts the FI document (Inventory Dr / GR-IR Cr) and creates an inspection lot, but the quantity sits in inspection status and is not freely available for issue until a usage decision is made.
Q: What is a usage decision and which movement types does it trigger?
The usage decision (QA11) is QC's verdict on an inspection lot. Accept moves stock from quality inspection to unrestricted via mvt 321; Reject posts to blocked/return — mvt 122 sends it back to the vendor. Until the decision is made, the stock can't be used.
Q: How is the GR routed into inspection in the first place?
Through the material's QM view / Inspection Setup: activating Inspection Type 01 (Goods Receipt for Purchase Order) tells SAP that a GR against a PO must create an inspection lot and place the stock in quality inspection. No QM view, no inspection — the GR goes straight to unrestricted.
Q: If QM isn't available in the system, can you still run a procurement GR?
Yes. QM in MM is optional. Without it, a standard GR mvt 101 posts directly to unrestricted stock and no inspection lot is created. You only get the quality gate (inspection stock + usage decision) once QM is activated and the material carries an active inspection type.
