Why is SAP integration complex?

Integration with SAP is complex for several reasons:

• Complexity of the SAP system itself: SAP is a comprehensive ERP system with many modules and business processes, requiring a deep understanding of its internal logic.
• Variety of interfaces: SAP supports different protocols and integration technologies (IDoc, BAPI, RFC, OData), which necessitates choosing the appropriate method and configuration.
• Non-standard customizations: Each company may heavily customize SAP, complicating integration and requiring adaptation of solutions.
• Security and authorization: SAP has complex access control mechanisms, requiring proper configuration of rights for integration users.
• Performance and load: Integration must consider the load on the SAP system to avoid disrupting its operation.

All these factors make SAP integration a technically and organizationally challenging task.
