| Challenge | Mitigation / Lesson | |-----------|---------------------| | – Consolidating decades of supplier master data caused duplication and inconsistencies. | Adopted a data‑cleansing sandbox and incremental migration with validation rules; engaged business SMEs for “golden record” approval. | | Change‑management resistance – Some regional purchasing teams were reluctant to abandon familiar spreadsheets. | Deployed a phased rollout with pilot sites, champion networks, and gamified training modules; achieved > 90 % adoption after 12 months. | | Integration latency with SAP S/4HANA – Initial API throttling led to delayed PO updates. | Implemented asynchronous event streaming (Kafka) and increased SAP CPI throughput; latency reduced from 30 min to < 5 min. | | Supplier digital readiness – Smaller suppliers lacked e‑procurement capabilities. | Launched a Supplier Enablement Programme offering free onboarding kits, webinars, and a lightweight mobile app for low‑tech users. | | Regulatory updates (e.g., EU Green Deal) – New reporting requirements emerged mid‑project. | Designed extensible data models with a “green‑layer” that can be activated without code changes; future‑proofs the platform. |

The portal is to use. REWE covers the platform cost. However, suppliers must bear their own costs for EDI setup (if chosen) or internal training. primus.rewe-groupe.com
