5 Common Mistakes to Avoid in SAP HANA Development

Starting an SAP HANA development project can revolutionize your company by enabling faster, more potent data processing and analytics. 

To avoid typical pitfalls that could cause your project to fail, careful planning and execution through SAP HANA are necessary when navigating this path. 

This post will discuss five typical blunders to avoid when developing SAP HANA applications and how to avoid them to guarantee success. 

1. Ignoring Adequate Data Modeling 

1.1 Hurrying Through Data Modeling: 

If you rush through data modeling, you can miss important details about how your data is structured. Additionally, it take time to understand your data needs and create a strong data model that helps your business goals. Also, you ensure your system can handle more data and work efficiently, saving you from costly fixes later on.

1.2 Disregarding Techniques for Data Compression: 

Disregarding data compression methods can result in slower SAP HANA performance and inefficient storage. Investigate compression choices like delta storage, run-length encoding, and dictionary encoding to maximize storage efficiency and enhance query performance. As a result, you can reduce storage costs and improve the overall performance of your SAP HANA environment by utilizing compression effectively. 

1.3 Neglecting Data Cleaning and Quality: 

When developing SAP HANA, data quality is crucial because erroneous or inconsistent data can taint your analytics and decision-making procedures. To guarantee that your data is accurate, comprehensive, and dependable, put strong data quality and cleansing procedures into place. By taking proactive measures to resolve data quality issues, you can increase the credibility of your SAP HANA applications and produce valuable business insights. 

2. Not Improving Query Performance 

2.1 Ignoring Indexing Strategies: 

In SAP HANA, Ignoring indexing strategies can lead to less-than-ideal query performance and protracted response times. Analyze your workload characteristics and query patterns to find areas where index optimization can be improved. However, useful indexes, such as bitmap, column, and full-text indexes, should be implemented to speed up query execution and enhance system performance.

2.2 Overusing Joins and Aggregations: 

Using excessive joins and aggregations in your queries can cause performance degradation and undue stress on your SAP HANA system. When possible, reduce the number of joins and aggregations in your query logic. To minimize, your computational overhead and optimize query processing, think about renormalizing your data or performing pre-calculations of aggregates. 

2.3 Ignoring Query Plan Analysis: 

Ignoring query plan analysis can result in poor SAP HANA performance and inefficient query execution. Regularly monitor and evaluate query execution plans to spot possible bottlenecks and areas for optimization. Moreover, to get insights into query behavior and optimize query performance, use tools like SQL Plan Cache and SQL Performance Monitor. 

3. Undervaluing the Upkeep and Monitoring of Systems 

3.1 Ignoring Continual System Upkeep: 

In SAP HANA, neglecting routine maintenance can lead to a decline in system stability, security flaws, and performance. Create a thorough maintenance plan that covers things like database backups, software updates, and system health checks. Proactively managing your SAP HANA environment can help you avoid problems before they start and guarantee the system’s continued dependability and efficiency.

3.2 Disregarding Metrics for Performance Monitoring: 

If you disregard performance monitoring metrics, you may not be aware of the functionality and state of your SAP HANA system. To spot patterns and abnormalities, keep an eye on key performance metrics including CPU, memory, disk I/O, and query response times. Utilize dashboards and monitoring tools to track performance metrics in real-time and take proactive measures to resolve any issues that may come up. 

3.3 Not Considering Growth and Scalability: 

Not considering growth and scalability can have an impact on your SAP HANA environment’s long-term viability. Consider future demands on workload and data growth when designing your system architecture, and keep scalability in mind. Take into account variables like hardware capacity, network bandwidth, and data distribution tactics to handle expansion in the future without compromising dependability or performance. 

4. Ignoring Security Considerations 

4.1 Ignoring Role-Based Access Control: 

If you ignore role-based access control (RBAC), you run the risk of allowing unauthorized access and security flaws in your SAP HANA system. Assign users explicit roles and permissions according to their duties and access needs. RBAC policies can be used to limit access to sensitive information and features, reducing the possibility of insider threats and data breaches.

4.2 Disregarding Data Masking and Encryption: 

Disregarding data masking and encryption methods exposes your private information to unwanted access and disclosure. Use encryption techniques like Transparent Data Encryption (TDE) for data at rest and SSL/TLS for data in transit. Protect sensitive data from unauthorized exposure by using data masking techniques to obscure sensitive information in non-production environments and ensure compliance with data privacy regulations. 

5. Ignoring Disaster Recovery and High Availability

5.1 Ignoring Redundancy and Failover Mechanisms: 

If redundancy and failover mechanisms are disregarded, your SAP HANA environment may become vulnerable to downtime and single points of failure. To guarantee the continuous availability of vital services and data, implement high availability (HA) solutions like system replication, failover clustering, and automated failover mechanisms. Enhance system architecture with redundancy and fault tolerance to minimize data loss and service interruptions.

5.2 Ignoring Backup and Restore Procedures: 

If you neglect backup and restore procedures, you run the risk of losing your SAP HANA data’s recoverability and integrity in the event of a disaster or system failure. Create strong backup and restore procedures that include regular database and log file backups in addition to thorough disaster recovery strategies. Regularly, test backup and restore procedures to swiftly recover from incidents with minimal disruption to business operations.


To maximize the value and impact of your investment in SAP HANA, it is imperative to avoid common mistakes in development. Meanwhile, by prioritizing proper data modeling, optimizing query performance, and maintaining proactive system upkeep and monitoring, you can overcome obstacles and harness the full potential of SAP HANA for your company. By taking proactive measures to avoid these pitfalls, you’ll position yourself to promote innovation, agility, and growth with SAP HANA. Additionally, consider incorporating DAS (Direct Attached Storage) solutions into your infrastructure to further optimize storage efficiency and enhance system performance.Read more on Tech
