Capstone Scenarios

• QuestionWhat is "Capstone A — From 0 to ATC-green"?Tap to revealAnswerScope with SCMON, escalate ATC variants DEFAULT to READINESS to CLOUD behind baselines with named owners, decide wrap-versus-rewrite per API, and govern decommissioning and business comms — fix code last, not first.
• QuestionIn "Capstone A — From 0 to ATC-green", explain:Tap to revealAnswerScope first with SCMON over a 1-3 month window to find the code that is actually executed.
• QuestionIn "Capstone A — From 0 to ATC-green", explain:Tap to revealAnswerEscalate ATC variants deliberately: DEFAULT, then S4HANA_READINESS_2023, then ABAP_CLOUD_DEVELOPMENT_DEFAULT.
• QuestionIn "Capstone A — From 0 to ATC-green", explain:Tap to revealAnswerGate each stage with a baseline plus an exemption process owned by named people.
• QuestionIn "Capstone A — From 0 to ATC-green", explain:Tap to revealAnswerUse a decoupling-cockpit matrix to decide wrap-versus-rewrite per standard API.
• QuestionAnalogy for "Capstone A — From 0 to ATC-green":Tap to revealAnswerIt is triage before surgery: survey what is alive, decide what to operate on versus splint, and brief the family before you cut.
• QuestionWhat is "Capstone B — Released-API-first new development"?Tap to revealAnswerBuild the full on-stack ABAP Cloud stack greenfield — CDS root entity over a Z table, a managed RAP BO with one validation and one determination, projection plus service plus OData V4, a DCL role, and tests — all ATC-clean against ABAP_CLOUD_DEVELOPMENT_DEFAULT.
• QuestionIn "Capstone B — Released-API-first new development", explain:Tap to revealAnswerModel one CDS root view entity over a Z table as the foundation.
• QuestionIn "Capstone B — Released-API-first new development", explain:Tap to revealAnswerBuild a managed RAP BO with exactly one validation and one determination.
• QuestionIn "Capstone B — Released-API-first new development", explain:Tap to revealAnswerExpose it via a consumption projection, a service definition, and an OData V4 binding.
• QuestionIn "Capstone B — Released-API-first new development", explain:Tap to revealAnswerMove authorisation into a DCL role tied to a PFCG authorization object.
• QuestionAnalogy for "Capstone B — Released-API-first new development":Tap to revealAnswerIt is building a house to code from the foundation up, so the inspection (ATC) passes without any retrofits.
• QuestionWhat is "Capstone C — Performance forensics"?Tap to revealAnswerMeasure top-down — SAT for the hot blocks, ST05 for the bad statements, PLANVIZ for each plan — then choose index, hint, CDS rewrite, or AMDP rewrite, and prove it with an acceptance test against the old runtime.
• QuestionIn "Capstone C — Performance forensics", explain:Tap to revealAnswerStart with SAT to find the time-dominant blocks (ABAP versus database).
• QuestionIn "Capstone C — Performance forensics", explain:Tap to revealAnswerUse ST05 to trace the SQL and surface the offending statements.
• QuestionIn "Capstone C — Performance forensics", explain:Tap to revealAnswerRun PLANVIZ per offender to read the actual per-statement execution plan.
• QuestionIn "Capstone C — Performance forensics", explain:Tap to revealAnswerApply the decision tree in rising order: index, hint, CDS rewrite, AMDP rewrite.
• QuestionAnalogy for "Capstone C — Performance forensics":Tap to revealAnswerIt is medical diagnosis: vitals (SAT), then targeted tests (ST05), then imaging (PLANVIZ) — you prescribe only once you can see the problem.

1. 1Map the core idea

   Analyse~10 min

   In your own words, map the central idea of "Capstone A — From 0 to ATC-green". Aim for one paragraph, no jargon you haven't earned.

   Done when: A non-expert could read your paragraph and explain it back to you.

   Re-read the source concept

2. 2Solve it to a real situation

   Apply~15 min

   Find a real situation from your own work / life where "Capstone C — Performance forensics" applies. Solve the idea — describe the situation, the move you'd make, and the alternative you considered first.

   Done when: You can name a specific situation (not a hypothetical), state your move, and explain the trade-off in one paragraph.

   Re-read the source concept

3. 3Teach it back

   Evaluate~5 min

   Pick someone (a colleague, a peer, a rubber duck) and explain the section to them in under 5 minutes. Use your own example, not the one from the lesson.

   Done when: Your listener can repeat the core idea + the trade-off back to you without prompting.

Why this matters. Reading + quizzing prove recall; applying it in a real situation is the only evidence of transfer. Treat at least one of these as non-negotiable before you move on.
