Efficient SAP Integrations: Key Strategies for Streamlined Operations

Unlocking Best Practices to Simplify SAP Integration and Boost Productivity

In today’s rapidly evolving business landscape, the integration of third-party systems with SAP has become crucial for organizations aiming to streamline their processes, optimize data flow, and enhance operational efficiency. By seamlessly connecting external applications with SAP, companies can achieve a unified and coherent IT ecosystem, which facilitates real-time data exchange, reduces manual intervention, and minimizes errors. This integrated approach not only enhances data accuracy and consistency but also empowers organizations to make informed decisions swiftly, ultimately driving productivity and fostering a competitive edge in the market.

Options for Integrating with SAP

There are several different methods and technologies for integrating SAP with third party solutions or other SAP products. These are some of the most common technical options for integration with SAP:

SAP Business Application Programming Interfaces (BAPI)

SAP Business Application Programming Interfaces is a standardized method for integrating with SAP systems. SAP BAPI allows for standardized integrations specifically for standard SAP processes and SAP internal integration scenarios. However, the method shows limited capabilities when it comes to complex integration scenarios, cloud based integration scenarios or integrations that require high level of customization.

Intermediate Document (IDoc)

Intermediate Document (Idoc) is a standard data structure used in SAP to facilitate data exchange between SAP and non SAP systems as well as SAP to SAP. It is particularly useful when handing asynchronous communication and batch processing. Moreover, the method is beneficial for large volumes of data and standard data exchange. IDoc integrations are not advantageous with real-time data exchange or when the target non-SAP system does not support for IDoc processing. Moreover, IDoc integrations show limitations in scenarios where extensive customization is needed.

SAP Cloud Platform Integration (SAP CPI)

Cloud Platform Integration (CPI) is a SAP cloud product that focuses on delivering a middleware for integration scenarios. While it is more tailored and straightforward to use for SAP related integrations, the middleware assists also for non-SAP to non-SAP scenarios. SAP CPI offers a variety of different other methods such as APIs, IDocs or oData. All these can be leveraged through SAP CPI, making it a central hub for all SAP related integrations. The benefits of CPI come with the fact that it allows for simple as well as complex integration scenarios, for both on-premise as well as cloud solutions. Moreover, it possesses a low cost of ownership due to leveraging a cloud product and scenarios are effective for real-time data exchange. One of the challenges that comes with SAP CPI are the fact that the solution is cloud dependent, meaning heavier restrictions are required with regards to security and control. Moreover, due to the nature of the product network latency might impact performance in some scenarios, especially in regions with limited cloud infrastructure. Additionally, SAP CPI requires training and familiarity for the users that have worked previously on for example PI/PO or other integration scenarios. Within Deloitte, we have the capability to help our customer to not only in building the integration scenarios in SAP CPI but also in ensuring that our customers gain the relevant know-how to implement these scenarios fully autonomous in the future.

Common Integration Scenarios

We recognize that in the current landscape, SAP tries to push more for clients to start utilizing SAP Cloud Platform Integration, especially regarding their mission to move many of the legacy systems towards cloud products. We can support with making the right choice for your integration scenario.

What are some of the most common integration scenarios that we have implemented for our clients?

1. Cloud-to-On-Premise Integration: One common scenario involves integrating cloud-based applications with on-premise SAP systems. For instance, integrating SAP SuccessFactors, a cloud-based human capital management solution, with an on-premise SAP ERP system. This integration enables seamless data flow between HR processes and financial operations, ensuring real-time access to employee data and streamlined payroll processing.

2. Third-Party Application Integration: Organizations often use a variety of third-party applications, such as CRM or e-commerce platforms, that need to communicate with SAP systems. Using SAP CPI, we integrated Salesforce, a leading CRM platform, with SAP ERP for one of our clients. This integration allowed for automatic synchronization of customer data, sales orders, and financial information, enhancing customer relationship management and reducing manual data entry.

3. Custom Application Development: When developing custom applications that need to interact with SAP systems, BAPIs provide a standardized interface. For a logistics client, we developed a custom mobile application for warehouse management that utilized BAPIs to access and update inventory data in real time. This solution improved inventory accuracy and streamlined warehouse operations.

4. SAP Module Integration: BAPIs are also effective for integrating different SAP modules. For a financial services client, we integrated SAP CRM with SAP ERP using BAPIs to unify customer data and streamline processes. This integration allowed for coordinated customer service and financial management, enhancing customer satisfaction and operational efficiency.

These are just some of the real-life examples that we have supported with our expertise in SAP related integration scenarios. We have covered integrations across all industries, whether with legacy on-premise systems or modern cloud solutions.

Challenges faced when Integrating (with SAP)

Integrating diverse systems within an organization is essential for streamlined operations and effective decision-making. However, it brings several challenges that need careful management.

1. Data inconsistency: Systems often store data in varying formats, leading to discrepancies that can disrupt business processes. To tackle this, organizations can implement data standardization processes and utilize data transformation tools to harmonize data formats. Establishing a centralized data repository as a single source of truth also helps maintain consistency across systems.
2. Complexity of system landscapes: Many organizations operate with a mix of legacy and modern systems, making integration both complex and costly. To address this, middleware platforms like SAP CPI can bridge diverse systems by supporting multiple protocols. Additionally, a gradual modernization approach, ensuring compatibility between old and new technologies, can simplify integration over time.
3. Security concerns: Integrating multiple systems can increase the risk of data breaches and unauthorized access. To mitigate these risks, organizations should implement robust security measures, including encryption and access controls, and conduct regular security audits. Ensuring compliance with data protection regulations is crucial for safeguarding sensitive information.
4. Change management is essential: Integration projects, often involve significant process and system changes that can lead to resistance. Engaging stakeholders early, clearly communicating the benefits of integration, and providing training and support can facilitate a smoother transition and encourage user adoption.

Best Practices when Integrating (with SAP)

When building integration pipelines, we have identified several best practice steps:

1. Design for scalability: It is important to start with rather a small data load and incrementally make the integration scenario more complex. Utilizing modular design principles enables components to be reused and scaled, facilitating easier updates and expansions.
2. Leverage pre-built content: This can significantly reduce development time. Many platforms, including SAP CPI, offer pre-packaged integration templates that can be customized to meet specific business needs. This approach accelerates deployment and minimizes manual coding efforts.
3. Maintain security: Implement robust security measures such as encryption and strict access controls. Regularly updating security protocols ensures compliance with evolving regulations and mitigates risks.
