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
