Model-specific APIs, batching, update groups, errors, CSRF and ETag concurrency.
Overview
Model-specific APIs, batching, update groups, errors, CSRF and ETag concurrency.
Lessons in this topic
- OData V2 and V4 consumptionOData V2 and V4 models expose different APIs and request lifecycles. For V4, group configuration controls when queued work is submitted. A successful outer batch response does not establish success of every enclosed business operation; inspect operation-level failures and pending state.
Interview questions covered
- What are key differences when consuming OData V4 instead of V2 in UI5?
- How do you handle errors from OData calls in a Fiori app?
