Salesforce–MuleSoft Integration with SAP: Building a Scalable IT Architecture for Modern Enterprises
MuleSoft introduction: Why Integration Requires More Than Simple Connectivity
In today’s fast-paced business environment, enterprises need more than just connected systems. Complex business and customer processes demand adaptive, reusable, and secure integration strategies. Leveraging Salesforce alongside MuleSoft API platform empowers SAP-based systems to seamlessly join modern digital ecosystems.
Understanding the Three-Layer API Architecture with MuleSoft
MuleSoft’s API-led approach divides integration into three layers, enabling modular and maintainable IT architecture:
1. System APIs: Direct Access to Source Systems
System APIs provide abstracted, secure access to backend systems such as SAP ECC, SAP S/4HANA, Salesforce, and Oracle without embedding business logic. Key functions include:
- Authenticated data retrieval (e.g., SAP Business Partner info)
- Transaction initiation (e.g., contract creation in SAP)
- Validation following source system rules
This separation ensures backend changes don’t impact business logic layers, improving system stability.
2. Process APIs: Centralized Business Logic and Data Aggregation
Process APIs implement business rules by combining data from multiple System APIs. They handle:
- Automated creation of SAP partners when new CRM clients are added
- Data merging from diverse sources into unified contract objects
- Status and decision logic enforcement (e.g., filtering archived SAP entries from CRM)
This layer maximizes business agility and reduces IT overhead for adapting evolving processes.
3. Experience APIs: Tailored Delivery to Applications and Channels
Experience APIs present data customized for user-facing platforms like:
- Salesforce UI
- Customer and partner portals
- Mobile apps, chatbots, dashboards
By reusing business logic across channels, Experience APIs enable consistent yet flexible user experiences.
MOHU Case Study: Real-Time Salesforce and SAP Integration Using MuleSoft
MOHU (Mol Hulladékgazdálkodási Zrt.) is a leading Hungarian waste management company specializing in sustainable environmental services and waste processing solutions, with an annual revenue exceeding €100 million. The MOHU project demonstrates how MuleSoft’s Anypoint Platform enables real-time, consistent data synchronization between Salesforce and SAP:
- System APIs connect SAP ECC via IDoc and REST interfaces
- DataWeave performs data transformations between SAP and Salesforce formats
- Process APIs govern contract statuses, partner IDs, and duplication
- Experience APIs serve Salesforce and admin portals
Process example:
A new contract in Salesforce triggers verification of the customer in SAP, creating a new Business Partner if needed, followed by synchronized contract recording and user confirmation in Salesforce.
