SAP / SAP Senior Level (10+ yrs) Interview questions
How do you build a business case for remediating existing core modifications toward a Clean Core state?
A compelling business case connects the technical remediation effort to concrete business outcomes rather than framing it as a purely technical "best practice" exercise — since remediation work competes for budget against features with more visible, immediate business value.
| Cost Argument | Value Argument |
| Rising upgrade cost/risk each cycle as modifications accumulate. | Unlocks eligibility for S/4HANA Cloud and its faster innovation cycle. |
| Growing knowledge-concentration/bus-factor risk in aging custom code. | Reduced total cost of ownership from smoother future upgrades. |
| Increasing support/troubleshooting cost near modified objects. | Positions the organization to adopt new SAP capabilities faster. |
The strongest business cases typically quantify the current trajectory (how upgrade cost/risk has grown over recent cycles) alongside the strategic option value unlocked by remediation, rather than presenting Clean Core as an abstract architectural ideal disconnected from measurable business impact.
Why is framing Clean Core remediation purely as a technical best practice often insufficient for securing budget?
What should the strongest business cases quantify alongside the cost argument?
