Introduction

• Speaker: Andre Fisher, Product Manager in the ABAP Development Group
• Main focus: Latest features in the RAP framework introduced in release 2308.

SAP Fiori Elements Feature Showcase

  • Enhanced search functionality (Ctrl + F) to navigate documentation.

SAP Logical Unit of Work (LUW)

• Logical Unit of Work: Important for managing transactional phases during data modifications.
• Phases:
  1. Injection Phase: User interaction for data changes.
  2. Early Save Phase: Prepares data for saving.
  3. Late Save Phase: Finalizes the save operation; a point of no return.
• Improvements in error handling and stability for developers:
  • New methods introduced: modify and save.
  • Clearer orchestration of transaction phases.

Background Processing Framework (BGPF)

• Purpose: Allows asynchronous processing for long-running operations.
• Configuration: Simplified setup, especially in cloud-based environments.
• How it works:
  • Uses a factory class to start execution after a commit work.
  • Supports both RAP apps and traditional background processing.
• Demo: Sending emails asynchronously based on data changes using the BGPF.

Local Events and Event Extension

• Introduction of Local Events: Ability to raise events locally, enhancing event handling.
• Event Handler Class: Implement a class to consume local events.
• Extending Events:
  • Create a managed event to add custom payloads to existing SAP events.
  • Example: Extend events to include additional data such as order item prices.

Conclusion

• New features in RAP provide enhanced stability, asynchronous processing capabilities, and improved event handling.
• Encouragement to explore these features in trial systems or SAP environments.
• Open to questions and feedback.
