Adaptation, extensibility and upgrade-safe delivery
Full lesson currently free to read · AI practice limits apply separately
Distinguish configuration and key-user adaptation from developer extensions and custom applications. Choose the least invasive supported option that satisfies the requirement and document its transport and upgrade path. Availability depends on the application and edition, not just the existence of a generic adaptation tool.
Visual overview
Explanation
Tutorial outcome
Distinguish configuration and key-user adaptation from developer extensions and custom applications. Choose the least invasive supported option that satisfies the requirement and document its transport and upgrade path. Availability depends on the application and edition, not just the existence of a generic adaptation tool.
Prerequisites
Complete chapters 1–14 in this module. Use synthetic fixtures or an authorized sandbox.
Worked case — fictional
A fictional team wants a renamed field and a new authorization-sensitive business action.
Step-by-step investigation
1. Classify
Separate the label/layout request from the new business action and its service requirements.
Expected evidence: A label change and a transactional action are different requirements.
2. Choose
Confirm which adaptation or extension mechanisms the actual application supports.
Expected evidence: Only documented options enter the design.
3. Secure
Keep authorization and validation behind the business action even if UI adaptation hides the control.
Expected evidence: A direct unauthorized service call is still rejected.
4. Promote
Record the artifact, transport mechanism and upgrade regression for each customization.
Expected evidence: Both the visual adaptation and action have release evidence.
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 chosen customization follows supported boundaries and remains testable after an upgrade.
Common failure to avoid
Do not modify generated app internals or mistake a hidden control for authorization.
Self-check
What should determine the customization mechanism?
Expected reasoning: The actual application's supported extensibility contract and business requirement.

Simulated training case. These observations are authored fixtures, not screenshots or results from a customer SAP system.
A fictional team wants a renamed field and a new authorization-sensitive business action.
Before you start
- Complete chapters 1–14 in this module. Use synthetic fixtures or an authorized sandbox.
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.
Classify
Separate the label/layout request from the new business action and its service requirements.
Expected evidence · simulated
A label change and a transactional action are different requirements.
Automatic playback is disabled by your reduced-motion preference. All steps remain available.
Try it, then verify
The chosen customization follows supported boundaries and remains testable after an upgrade.
Watch for: Do not modify generated app internals or mistake a hidden control for authorization.

Real project scenario
A fictional team wants a renamed field and a new authorization-sensitive business action.
Common mistakes
Do not modify generated app internals or mistake a hidden control for authorization.
Best practices
The chosen customization follows supported boundaries and remains testable after an upgrade. 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.
Interview angle
What should determine the customization mechanism? The actual application's supported extensibility contract and business requirement.
