Summary of “Part 1: SAP RAP Transaction App - Managed Scenario: Introduction”

This tutorial video introduces a step-by-step guide to developing an SAP RAP (RESTful ABAP Programming) transactional OData application using the managed scenario. The focus is on creating a fully functional transactional app for managing contact details with capabilities such as create, update, delete, validations, determinations, and actions.

Key Technological Concepts and Product Features Covered

SAP RAP Managed Scenario
- Development of OData services with transactional capabilities.
- Use of behavior definitions to enable create, update, delete, validations, actions, and determinations.
- Introduction to Behavior Definition Language (BDL) for defining entity behavior.
- Behavior implementation via a behavior pool (local handler class).
Data Modeling Artifacts
- Creation of a database table (ZMS_CONTACT) to hold contact details.
- Use of UUID as the key field for automatic key generation by RAP framework.
- Fields include contact ID, first name, middle name, last name, gender, date of birth, age, telephone, email, and active status.
- Addition of administrative fields for locking and concurrency control.
Domain and Data Element Creation
- Custom domain and data element for the gender field.
- Domain includes allowed values such as Male, Female, LGBTQ+, Unspecified, and Not willing to specify.
Core CDS Views
- Interface view (root entity) created on top of the database table.
- Projection view created on the interface view, defined as a transactional query.
- Use of provider contract to define the root entity and transactional behavior.
Metadata Extensions for UI Annotations
- Separation of UI annotations from CDS entity definitions using metadata extension artifacts.
- Metadata extensions allow defining UI-specific annotations like line item display, labels, and field positions.
- Annotation @Metadata.allowExtensions: true enables creation of separate metadata extension files.
Service Definition and Binding
- Plan to expose the contact entity via a service definition.
- Service binding to be created with OData V2 protocol for consumption.
- Preview function used for testing the service without creating a Fiori app.
Additional Features Planned
- Adding associated entities (e.g., addresses linked to contacts).
- Optionally creating Fiori apps in future tutorials using SAP Business Application Studio.
