SAP ABAP Developer Challenge

4-week challenge exploring SAP Joule for Developers (J4D) — ABAP AI capabilities in Eclipse ADT.

---

Week 1 — Fusion Development with ABAP Cloud in SAP Build

• Set up SAP BTP ABAP trial and configured Eclipse ADT
• Built a ShoppingCart app using RAP (database table, CDS views, behavior definition, OData service)
• Added determinations and validations
• Deployed a Fiori Elements app via SAP Business Application Studio
• Created an IAM app for authorization in ADT

Week 2 — Movie Tracker App + Joule Explain

• Created Movie Tracker RAP app using Joule Chat in the OData UI wizard
• Added virtual Profit field (Revenue - Budget) and AudienceCategory CASE logic in CDS
• Used Joule Explain to understand the CASE statement

Week 3 — Validation + Joule RAP Predict Business Logic

• Made Title field mandatory and defined a validation in the behavior definition
• Used Joule RAP Predict Business Logic to generate validation logic — throws error if Title is empty

Week 4 — Determination + Joule Predictive Code Completion

• Added YearsSinceRelease field and defined a determination triggered on ReleaseDate change
• Used Joule Predictive Code Completion to implement the calculation logic
• Key fix: used on modify { field ReleaseDate; } instead of on modify { create; update; } to avoid infinite loop short dump
