Fiori elements and annotations

Fiori elements consumes service metadata and annotations to build supported floorplans. Diagnose an absent column by comparing metadata, annotation targeting and visibility before adding custom controller code. Keep UI annotations separate from business authorization and service validation.
Visual overview
Explanation
Tutorial outcome
Fiori elements consumes service metadata and annotations to build supported floorplans. Diagnose an absent column by comparing metadata, annotation targeting and visibility before adding custom controller code. Keep UI annotations separate from business authorization and service validation.
Prerequisites
Complete chapters 1–6 in this module. Use synthetic fixtures or an authorized sandbox.
Worked case — fictional
A fictional list report omits a delivery date even though the service returns that property.
Step-by-step investigation
1. Metadata
Confirm the property exists with the expected type and entity target in the service metadata.
Expected evidence: DeliveryDate is present on the order entity.
2. Annotation
Check that the line-item annotation targets the correct entity and property.
Expected evidence: The annotation points to DeliveryDate, not ShipDate.
3. Render
Reload using the supported cache and metadata refresh process for the test runtime.
Expected evidence: DeliveryDate is available in the list configuration.
4. Validate
Test small screens, personalization and a role that cannot read the record.
Expected evidence: UI visibility changes do not grant backend access.
Try it yourself
Reproduce the synthetic input from the example below in a local fixture or authorized sandbox. Follow each step, record the observed result, and explain any mismatch before continuing. Do not treat the expected evidence as a result observed in your SAP tenant.
Acceptance check
The intended field is exposed through the supported floorplan without bypassing backend rules.
Common failure to avoid
A UI annotation does not grant data access or make an unsupported extension API stable.
Self-check
When should you add custom UI code for a missing field?
Expected reasoning: After checking the service and annotation contract and the supported floorplan behavior.
Edition and release scope
Check the linked SAP documentation for your product, runtime, region and enabled service plan. The worked case is a simulation; these steps were not executed in a customer SAP tenant.
SAP references
References checked 2026-10-30. SAP material supports the named concepts; the case, fixture and acceptance checks are original ERPClimb teaching material. No SAP tenant execution or certification is claimed.

Common mistakes
A UI annotation does not grant data access or make an unsupported extension API stable.

Interview questions
1. How do you build a list report and object page with Fiori elements?
Answer it in your own words first, then compare.
2. A field shows a technical code instead of its description. How do you fix it in Fiori elements?
Answer it in your own words first, then compare.
