Purpose
- Secure materials at the right time, cost and quality
- Keep procurement auditable through linked documents
Key documents
- PR (ME51N) — internal demand
- PO (ME21N) — legal commitment to vendor
- GR (MIGO) — goods receipt, posts inventory
Common issues
- Price or quantity mismatch blocks invoice
- GR/IR clearing account not balanced
- Missing source of supply on the requisition
Key takeaway
Every step in MM is a document that references the one before it — the three-way match is what makes the cycle auditable.
