SAP BW Resource (Hands-on ABAP) — Redesign/Recreate Flow
Upgrade scenario: SAP ECC Special Ledger (FI-SL) → ECC New GL (and S/4-ready)
Role scope (owns)

• Assess current FI-SL→BW flow (DataSources, deltas, process chains, transformations, reports) and define the target New GL sourcing
• Redesign and rebuild end-to-end extraction from ECC New GL into SAP BW (Business Warehouse), replacing FI-SL dependencies where needed
• Perform extractor enhancement (ABAP) and BW-side replication, transformations, DTPs, and load orchestration
• Ensure delta correctness (init/re-init, queue/serialization, debugging) and financial reconciliation (FI-SL vs New GL during transition; New GL vs BW post cutover)
• Deliver cutover plan (backfill/historical reload approach, freeze window, rollback, runbook) and stabilize post-go-live
