Study Notes

Application Development in SAP HANA Cloud

Mandatory steps for CRUD application development include defining services, adding SAP Fiori UI, and defining the data model.
SAP Fiori elements generate UIs using annotations in the OData service and the entity definition of the service.

Tools and Technologies

To build Spring Boot applications with SAP Cloud SDK, required tools are Java SE Development Kit 8 and Apache Maven version 3.5 or above.
YAML files serve as configuration files and rely on correct indentation, and are valid JSON files.

CAP SDK and Error Handling

The CAP SDK for Node.js throws a FOREIGN_KEY_VIOLATION error for foreign key constraint violations.
Custom error handlers must be registered for the "on" phase of the error handling.

SAP Business Application Studio and Git

The proper sequence for local file management in Git involves checking out, creating, modifying, saving, staging, and committing changes.

SAP Build Process Automation

Decision tables consist of tabular input/output rule expressions and are used to define process conditions.
Policies in SAP Build Process Automation are collections of business rules.

CI/CD and Application Deployment

To implement a CI/CD job, the project must be shared with a remote Git repository.
A manual CI/CD build can be triggered without Git changes by selecting "Trigger a Build" in the job's context menu.

Kubernetes and API Rules

Kubernetes features include immutability, self-healing, service discovery, and load balancing.
Creating an API Rule generates an Istio VirtualService automatically.

Authentication and Authorization

Maintain routes during design time in the xs-app.json file to secure applications in Cloud Foundry.
User access in SAP BTP subaccounts requires the assignment of role collections.

SAP Fiori Elements and User Interface

SAP Fiori elements are preferable when standard floorplans suffice or when speed is prioritized over flexibility.
Recommended floorplan for tasks with multiple item views and single data visualization is the Worklist.

Event Handling and CAP

Events in CAP can be specified to trigger actions after or before certain processing occurs.
For side-by-side extensions, both SAP-delivered business objects and custom CDS views can have OData services enabled.

Best Practices in Development

Avoid catching programming errors and unexpected errors according to best practices.
Application errors should be logged; try/catch blocks should be used judiciously.

Container Management

Pulling container images from private registries requires creating a secret with type "kubernetes.io/dockerconfigjson" and providing credentials via imagePullSecrets.

SAP Business Technology Platform Use Cases

The platform supports integrating apps, data, and processes, building innovative digital apps, and extending cloud and on-premise apps.
Key elements of reactive systems in extensions are asynchronous communication and loose coupling between systems.### Access Restriction Steps
Set Scopes element to the required scope name in xs-app.json file.
Specify role-name attribute in web.xml for required role template.
Define role template in xs-security.json file to manage access.
Configure Scopes element in xs-security.json for access control.

OData Supported Formats

JSON is a supported data format for OData.
XML-based AtomPub is also a valid format for OData.
Other formats like YAML and XHTML are not supported by OData.

Twelve-Factor Application Guidelines

Traceability and reproducibility of changes is essential.
Stateless and self-contained application processes enhance reliability.
Separation of application code and runtime configuration is a fundamental principle.
Cache management and security management are not primary twelve-factor guidelines.

Logic Flows Characteristics

Logic flows consist of a sequence of events, actions, and functions.
They can customize various behaviors within an application.
Logic flows can be simple or branching, allowing for complex logic without mandatory decision loops.

SAP Cloud SDK Scenarios

The SDK offers advanced features like resilience and caching for applications.
It allows the addition of new features to existing Java applications but does not cater to .NET applications.

SAP S/4HANA Cloud Extensions

Extensions are unaffected by SAP S/4HANA Cloud's quarterly updates due to stable public interfaces.
The extension application operates on SAP Business Technology Platform, ensuring consistency across updates.

Kyma Eventing Prerequisites

A Subscription CR is required for functions to receive events.
Functions must comply with CloudEvents specification to handle events effectively.

SAP Build Process Automation Features

Templated automations streamline the development process.
Plug-and-play availability of components enhances speed in development, while other features may not contribute as significantly.
