Integrating external systems with SAP can be a significant challenge, but with the right approach, it can transform your business operation.
The most common mistake we see is trying to do synchronous integrations for everything. SAP is designed for certain usage patterns, and forcing others can cause performance issues.
Our recommendation: use message queues for operations that do not require an immediate response, and reserve synchronous calls only for critical validations.
Another crucial point is error handling. Integrations fail, and your system must be prepared to handle those failures gracefully.
