Training and Deploying Custom AI Models In SAP

AI is playing a bigger role in enterprise technology, and SAP consultants are increasingly working with AI models to automate tasks, improve decision-making, and boost efficiency.?

SAP Business Technology Platform (BTP) provides tools for developing, training, and deploying AI models, integrating them directly with SAP applications to meet enterprise-scale demands.

Within SAP BTP, there are several AI-focused services, each designed for a specific stage of implementation.

SAP AI Core is where model training and deployment happen, while SAP AI Foundation helps with governance and monitoring. SAP HANA ML enables in-database machine learning for structured data tasks, reducing data transfers, while deep learning models require SAP AI Core. SAP Datasphere takes care of data integration across different sources.

A lot of organizations are already using AI-powered solutions, but when consultants train custom AI models within SAP BTP, they can shape AI to fit a company’s exact workflows, data, and compliance requirements.

Rolling out AI in SAP is a multi-stage process: preparing and structuring data, training and fine-tuning models, deploying them, embedding them into SAP applications, and continuously monitoring performance. Each step comes with its own technical and strategic challenges, and the responsibility of SAP consultants to make sure the implemented AI is not just functional, but scalable, cost-effective, and truly valuable to the business.

This article from IgniteSAP covers the main considerations of SAP consultants when implementing AI in SAP systems.

Preparing Data for AI Model Training

AI models are only as good as the data they’re trained on. In SAP environments, relevant data is often spread across SAP HANA, SAP BW/4HANA, SAP Data Warehouse Cloud, SAP S/4HANA, and external sources. Before training can begin, data must be consolidated, cleansed, and structured for machine learning.

SAP Datasphere is now used in data preparation, providing integration, transformation, and governance tools to ensure data quality. It allows SAP consultants to extract structured and unstructured data, apply preprocessing techniques, and deliver the right input for models. This includes handling missing values, normalizing numerical data, encoding categorical variables, and filtering out irrelevant features.

Governance and security must be addressed early. SAP systems handle sensitive business data, making compliance with the EU’s GDPR and industry regulations a priority. Data masking, anonymization, and access controls should be applied to maintain compliance.

Another key factor is data freshness. Some AI models rely on real-time feeds, while others perform well with historical datasets. SAP consultants must decide whether streaming pipelines (SAP Integration Suite) or batch processing (SAP Datasphere, SAP HANA ML) is the right approach.

Training AI Models in SAP BTP

With data prepared, the next step is model training. SAP BTP offers multiple options depending on model complexity and data type.

SAP AI Core supports frameworks like TensorFlow, PyTorch, and Scikit-learn, enabling consultants to build or fine-tune models. Training runs in containerized Kubernetes environments, making it scalable. Since AI Core primarily uses CPU-based infrastructure, deep learning models may require external GPU training before deployment.

For structured business data, SAP HANA ML offers an integrated approach. Rather than training models in a separate environment, HANA ML runs machine learning directly within SAP HANA Cloud, reducing latency and eliminating data transfers. This makes it ideal for predictive analytics, customer segmentation, fraud detection, and financial forecasting, while SAP AI Core remains the choice for deep learning use cases.

During training, hyperparameter tuning and performance monitoring are essential. SAP AI Core allows consultants to adjust learning rates, optimize feature selection, and compare model iterations. Performance is measured using accuracy, precision, recall, and F1-score, ensuring business requirements are met before deployment.

SAP AI Core also provides version control and a model repository, making it easy to track changes and compare iterations. As business needs evolve, models require regular retraining with updated data to stay accurate. Past versions can be referenced or restored if needed.

For high-performance AI applications, SAP consultants may train them externally on AWS SageMaker, Google Vertex AI, or Azure ML and then deploy them in SAP AI Core for inference. This significantly reduces training time and costs while keeping AI models tightly integrated with SAP workflows.

Deploying AI Models in SAP BTP

Once a model is trained and validated, it must be deployed in production to generate real-time or batch predictions. SAP AI Core enables deployment via containerized applications, allowing models to be registered, managed, and accessed through REST APIs by SAP applications.

The choice between real-time and batch inference depends on the use case:

Real-time inference is best for fraud detection, dynamic pricing, and AI-powered chatbots, where immediate responses are required. These deployments must be low-latency and highly available, delivering predictions in milliseconds.

Batch inference is ideal for demand forecasting, customer churn analysis, and financial risk assessments, as predictions are generated at scheduled intervals.

Efficient scaling of AI models is essential. SAP AI Core runs in Kubernetes-based environments, allowing consultants to manually configure workload scalability. However, large-scale AI workloads can be costly, so caching, model optimization, and potential integration with external AI services should be considered.

AI models require continuous monitoring and retraining as business conditions change. Automated pipelines can track inference accuracy and trigger retraining when necessary.

Finally, security and compliance must be part of deployment strategies. AI-generated decisions impact core business processes, so access must be restricted to authorized users, predictions logged for auditability, and explainability tools applied. SAP AI Foundation provides governance and transparency frameworks, helping consultants implement AI compliance, monitoring, and explainability best practices, though bias detection requires additional measures.

Integrating AI Models into SAP Applications

Once an AI model is deployed in SAP AI Core, the next step is integrating it into SAP applications. AI-generated predictions must be embedded into decision support, automation, and analytics workflows to be effective.

A common integration method is REST APIs, which allow SAP applications like SAP S/4HANA, SAP Fiori, and SAP Ariba to send data and receive AI-generated insights in real time. This is widely used in automated invoice processing, fraud detection, and supply chain risk management, where AI continuously informs SAP applications.

For event-driven AI execution, SAP Event Mesh triggers models based on business events. An AI model can flag a high-risk transaction for SAP S/4HANA’s finance module, or SAP Intelligent RPA can automate repetitive tasks by pairing AI with robotic process automation.

SAP Analytics Cloud (SAC) integrates AI-driven forecasts through its Smart Predictive Planning feature and external AI model connections, helping users make informed decisions. SAP Fiori applications can also integrate AI-generated recommendations, alerts, and risk scores directly into the user interface.

SAP Joule Generative AI is now embedded in SAP S/4HANA, SAP SuccessFactors, SAP Ariba, and SAP Service Cloud, providing natural language interactions, report summarization, and workflow automation. SAP Joule APIs give SAP consultants the ability to build chatbots, decision support tools, and AI-powered document workflows, making generative AI highly customizable within SAP applications.

Because AI influences core business processes, security and governance must be part of the integration strategy. Access control policies should restrict AI usage, and audit logs should track AI-driven decisions. SAP AI Foundation provides governance tools, but internal policies for bias detection, explainability, and risk assessment should also be in place before fully embedding AI into SAP systems.

Managing AI Models in Production

Deploying an AI model isn’t the final step: ongoing monitoring and maintenance are essential to keep models accurate and relevant. As business conditions change and data patterns shift, AI models can become outdated if left unattended.

SAP AI Core provides monitoring and logging tools to track key performance metrics like accuracy, precision, recall, and inference latency. If performance declines, retraining workflows should be triggered to update the model with fresh data.

Version control is also important. SAP AI Core’s model repository allows consultants to roll back to previous versions if a newer model underperforms. Testing updates in a controlled environment before full deployment helps prevent business disruptions.

For AI models in regulated industries like finance and healthcare, explainability and fairness checks must be continuous. SAP AI Foundation offers bias detection and transparency tools, but SAP consultants should also work with business stakeholders to periodically review AI-driven decisions in areas like hiring, loan approvals, and fraud detection.

Automating retraining processes improves AI lifecycle management. Scheduled retraining jobs within SAP AI Core keep models current, while active learning techniques allow models to refine themselves with real-time data.

Cost optimization is another key consideration. Running AI workloads in SAP AI Core incurs compute, storage, and API costs, so monitoring resource usage and scaling efficiently is necessary. High-frequency inference models should be optimized for low-latency execution, while batch processing workloads can be scheduled during off-peak hours to reduce costs.

Without careful planning, AI costs can escalate quickly, so SAP consultants must carefully balance performance, efficiency, and scalability when running AI workloads in SAP BTP.

Optimizing AI Inference and Performance in SAP BTP

Selecting the right inference approach is key to balancing performance and cost.

Real-time inference is essential for applications like fraud detection, dynamic pricing, and recommendation engines, but these require continuous compute resources. Batch inference, used for customer churn prediction, demand forecasting, and financial risk assessments, is more cost-effective, as models run on a scheduled basis rather than in real time.

For structured data tasks, SAP HANA ML offers a more efficient alternative to deploying a separate AI model in SAP AI Core. Running models directly inside SAP HANA eliminates unnecessary data transfers, reducing both latency and processing costs—a strong fit for predictive sales analytics and supply chain optimization.

AI models should also be optimized for performance. Techniques like quantization and pruning reduce model size without sacrificing accuracy, helping AI models run faster and use fewer resources when deployed in SAP AI Core. For enterprises running large-scale AI workloads, especially deep learning models requiring GPU acceleration or multi-cloud deployments, a hybrid AI strategy may be beneficial.

Instead of handling all model training within SAP AI Core, businesses can train models externally using AWS SageMaker, Google Vertex AI, or Azure ML for GPU/TPU acceleration, then deploy them in SAP BTP for inference. This approach leverages hyperscaler computing power while maintaining tight integration with SAP systems.

Challenges in AI Training and Deployment

While AI adoption in SAP environments brings significant benefits, there are challenges that SAP consultants must anticipate.

SAP Datasphere and SAP HANA preprocessing tools improve data quality, but bias mitigation requires feature selection strategies and regulatory compliance measures.

Deploying an AI model is only part of the process: if the model’s predictions aren’t properly integrated into SAP workflows, its impact will be minimal. SAP consultants should work closely with business process owners to ensure that AI-driven insights feed directly into SAP Fiori applications, SAP S/4HANA decision workflows, or SAP Analytics Cloud dashboards.

AI models in SAP environments must comply with industry regulations, whether for financial audits, data privacy laws, or HR decision transparency. SAP AI Foundation’s explainability and bias detection tools help with compliance, but manual audits and AI oversight committees should be in place for mission-critical AI applications.

The Future of AI in SAP BTP: What’s Next for SAP Consultants?

AI is becoming a core capability within SAP BTP, shifting the role of SAP consultants from custom AI development to AI configuration and integration. As pre-trained models and AI services expand, consultants will focus more on adapting and embedding AI into business processes rather than building models from scratch.

With AI regulations tightening, expertise in governance, compliance, and ethical AI deployment will be increasingly valuable: especially in regulated industries like finance and healthcare. Understanding bias detection, explainability, and AI auditing will be valuable consulting skills as businesses prioritize transparent and accountable AI implementations.

The demand for AI Solution Architects and AI Integration Specialists will grow, requiring consultants to bridge the gap between AI technology and SAP business applications. Additionally, multi-cloud AI strategies will become standard, making experience with AWS, Google Cloud, and Azure AI tools a key advantage.

AI-powered documentation, system diagnostics, and workflow automation tools will accelerate consulting tasks, making AI not just something to deploy, but a tool to improve SAP project efficiency.

The best-prepared consultants will cultivate SAP AI competency as a core skill, positioning themselves as indispensable advisors for customers adopting AI in their IT systems.?
