Develop extensions with CAP following the SAP BTP Developers Guide — Lesson 1: SAP BTP Extension Strategy, Clean Core, CAP Architecture, and Project Setup

Learning Objectives

• Interpret the SAP structures, master data, settings, roles, and dependencies relevant to this lesson.
• Perform the lesson workflow and create a reviewable CAP extension architecture blueprint.
• Evaluate the situation where the extension duplicates functionality already available in the core and choose proportionate corrective action.

Detailed Topics

• SAP BTP Extension Strategy applied to the course scenario, system behavior, and expected evidence.
• Clean Core applied to the course scenario, system behavior, and expected evidence.
• CAP Architecture applied to the course scenario, system behavior, and expected evidence.
• and Project Setup applied to the course scenario, system behavior, and expected evidence.

Instructor Demonstration

The instructor traces an end-to-end case involving a development team extending an SAP application without modifying the digital core. The demonstration explains system navigation, configuration dependencies, transaction results, and the evidence recorded in CAP extension architecture blueprint. It also tests the exception where the extension duplicates functionality already available in the core.

Hands-On Exercise

Complete a controlled exercise for SAP BTP Extension Strategy, Clean Core, CAP Architecture, and Project Setup. Confirm the business or technical objective, perform the required SAP steps, capture results, investigate the stated exception, and preserve the final outcome in CAP extension architecture blueprint.

1. Confirm scope, prerequisites, master data, roles, configuration dependencies, and expected results.
2. Execute the process while recording transactions, settings, observations, and system messages.
3. Test normal behavior, the stated exception, and one integration or authorization dependency.
4. Document corrections, owners, verification steps, review triggers, and operational handover notes.

Scenario Analysis

• Identify the SAP object, rule, setting, or process step with the strongest influence on the result.
• Compare two defensible responses and explain their business, technical, control, and evidence trade-offs.
• Determine how the CAP extension architecture blueprint should be approved, retained, retested, and updated.

Troubleshooting Guidance

Begin where expected SAP behavior first differs from the observed result. Check organizational assignments, master data, configuration sequence, authorization, integration, and transaction evidence separately. Treat “the extension duplicates functionality already available in the core” as a hypothesis until the relevant settings, logs, documents, and process outcomes confirm the cause.

Validation Checklist

• Required SAP structures, master data, roles, settings, and dependencies are present.
• The CAP extension architecture blueprint connects the final conclusion to reviewable system evidence.
• Normal processing, the stated exception, integration behavior, and follow-up were tested.
• Corrections, ownership, retest criteria, documentation, and operational handover are complete.

Lesson Outcome

Learners can perform SAP BTP Extension Strategy, Clean Core, CAP Architecture, and Project Setup, explain the system behavior, and defend the result through CAP extension architecture blueprint.
