Having looked at different extensibility and integration scenarios for SAP Build Work Zone already, one aspect is shared across most, or even all scenarios: How can the user authentication with the integrated business application be handled securely? As outlined in the previous lessons, the SAP BTP connectivity service plays a critically important role in ensuring such a secure connection can be established. While the default choice (for example, when creating a UI Integration card) will likely have a direct connection from SAP Build Work Zone <> SAP BTP <> (SAP) business application, there are cases where more complex, enterprise grade integration patterns, are required.
Understanding Different Backend Integration Scenarios
Instead of leveraging a direct connection, there can also be integration setups that leverage principal propagation with SAP BTP to forward the principal (identity of a user) across several connections in a complex system landscape. This helps to avoid using technical users in each of the systems involved.
This lesson will cover several integration use cases where principal propagation can be applied.
