1. Procurement Cycle

PR (ME51N) → RFQ (ME41) → Quotation (ME47) → PO (ME21N)
→ GR (MIGO 101) → IV (MIRO) → Payment (F110)

Shortcut flows:

• Without RFQ: PR → PO (ME58 — auto-convert PR to PO)
• Consignment: PO item cat K → GR → settlement (MRKO)
• Subcontracting: PO item cat L → GI components → GR finished

2. Purchase Order Issues

Account assignment errors

• Category K (cost center): cost center must exist and be active
• Category A (asset): asset master must exist, depreciation area active
• Category F (internal order): order must be in Released status
• Category P (project/WBS): WBS element must be open for costs

Tolerance check (MIRO)

• OMR6 → tolerance keys: BD (amount) / VP (moving avg price variance) / PP (price)
• Tolerance = percentage + absolute amount — both must be within limits

GR-based invoice verification

• PO item → Invoice tab → GR-Based IV flag = X
• With flag: MIRO only possible after GR; invoice quantity = GR quantity
