An SAP code review is a detailed analysis of custom-developed code within your SAP environment. It focuses on identifying security vulnerabilities, insecure logic, and poor development practices that could expose your systems to risk.
Unlike infrastructure-focused assessments, a code review goes directly into the application layer. It examines how business logic is implemented and whether that logic can be abused.
At Vicxer, SAP code reviews target both ABAP and Java developments, providing deep insight into how custom code impacts your overall security posture.
Why SAP Code Reviews Are Critical
Custom code is one of the most common sources of security vulnerabilities in SAP systems. Even well-configured environments can be compromised through insecure development practices.
Common challenges include:
- Lack of secure coding standards
- Insufficient validation of user input
- Over-reliance on standard authorizations without context checks
- Legacy code that was never reviewed for security
Since custom developments often support critical business processes, vulnerabilities at this level can have direct operational and financial impact.
Our Approach to SAP Code Review
We combine automated analysis with expert manual validation to ensure accurate and meaningful results.
Code Discovery and Scope Definition
The process begins by identifying which developments should be analyzed. This includes:
- Custom ABAP programs, reports, and function modules
- Enhancements, user exits, and BAdIs
- Custom Java applications in SAP environments
- High-risk or business-critical code paths
This ensures the review focuses on areas with the highest potential impact.
Automated Code Analysis
We use specialized tools to scan the codebase and detect patterns associated with known vulnerabilities.
This includes:
- Missing authorization checks
- Hardcoded credentials or sensitive data
- Insecure data handling
- Use of unsafe functions or APIs
Automation enables broad coverage and fast detection of common issues.
Manual Expert Review
Automated tools alone are not enough. Our security experts manually analyze the code to identify complex or context-specific vulnerabilities.
This step focuses on:
- Business logic flaws that could be exploited
- Improper use of authorization objects
- Data exposure risks across transactions or interfaces
- Privilege escalation scenarios
Manual validation reduces false positives and ensures that findings are relevant and actionable.
Actionable Remediation Guidance
We provide clear, developer-friendly recommendations to fix identified issues.
These include:
- Secure coding alternatives and patterns
- Input validation and output handling improvements
- Proper authorization checks and controls
- Refactoring guidance for insecure logic
The goal is not only to fix vulnerabilities, but also to improve long-term development practices.
Key Benefits of Vicxer’s SAP Code Review
A structured SAP code review delivers measurable security improvements:

When Should You Perform an SAP Code Review?
Code reviews are especially important in scenarios such as:
- Before deploying new custom developments
- During SAP S/4HANA migrations or transformations
- After major changes in business processes
- When onboarding new development teams
- As part of ongoing secure development practices
