Complex Data Migration
Transitioning from SAP ECC to S/4HANA requires meticulous planning for data migration. Over 50% of projects face delays due to unforeseen data complexities. It's crucial to cleanse and prepare data beforehand to avoid bottlenecks and ensure seamless migration.
Custom Code Adaptation
Custom code developed for SAP ECC often doesn't automatically work with S/4HANA's architecture. Approximately 30% of custom codes need rework or optimization. Understanding the Simplification List in S/4HANA is critical to identify obsolete or redundant codes.
Integration Challenges
S/4HANA brings enhanced functionalities but also new integration challenges. Systems reliant on ECC may require significant interface updates. Surprisingly, up to 25% of integrations may need complete redesign to align with S/4HANA’s digital core capabilities.
User Training and Adoption
Switching to S/4HANA isn't just a technical upgrade; user adoption is vital. Studies show that projects with comprehensive training experience 40% higher success rates. Investing in user education can bridge the gap between new functionalities and practical usage.
Cost and Time Management
The upgrade involves significant investment in both time and resources. On average, a midsize company may invest 12-18 months and substantial financial resources. Efficient project management and realistic timelines are crucial to avoid budget overruns and project delays.Unexpected Data Volume
A single S/4HANA migration generated 100 TB of data logs in one week, overwhelming storage systems. Proper monitoring is essential.
