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.
