How did your system receive data from SAP? Describe the integration architecture and your personal contribution to its design.

Standard interfaces such as IDoc, BAPI, OData, or SOAP API are typically used for integration with SAP. The architecture is often built on a middleware layer that processes requests and data between SAP and external systems.

Example architecture:

• SAP ERP as the data source
• Middleware (e.g., SAP PI/PO, MuleSoft, Apache Camel) for data transformation and routing
• External system consuming the data

My contribution involved designing the data exchange schema, selecting message formats and protocols, as well as configuring and testing integration scenarios. I developed data mappings, ensured error handling, and participated in optimizing exchange performance.
