Document Overview

This comprehensive troubleshooting guide is a systematic diagnostic framework for IBP consultants.

What This Guide Covers

This guide provides end-to-end troubleshooting coverage across the full SAP planning landscape:

1. SAP IBP: Planning runs, optimizer, forecasting, capacity, data/key figures, security, performance, Excel add-in
2. S/4HANA Sourcing & Procurement: MRP/PR/PO creation, vendor determination, master data traps
3. S/4HANA ePPDS: Production scheduling, component shortages, order release, capacity/master data
4. Integration: CIF/CI-DS replication, data quality, transformation failures, mapping

The 80/20 Rule of SAP IBP Troubleshooting

CRITICAL: 80% of IBP planning failures trace to S/4HANA master data or execution blocks—NOT IBP configuration

This fundamental insight drives our troubleshooting approach:

1. 50% Master data issues (production versions, work centers, MRP settings)
2. 30% Integration gaps (CIF delays, transformation errors, mapping)
3. 20% IBP configuration (optimizer, forecast models, key figures)

Guiding Principles (High Leverage)

1. Start from the symptom: Accurately describe what’s broken before diving into diagnostics
2. Trust execution systems: When IBP and S/4HANA disagree, trust ePPDS for execution feasibility
3. Verify integration health first: CIF/CI-DS failures cause silent data sync issues
4. Validate assumptions: Never assume master data is correct—verify it systematically
5. Document patterns: Keep resolution notes for pattern recognition and prevention
6. Backup before changes: Always export/backup configuration before making changes
