SAP Service Cloud Version 2 incorporates several AI-driven features to enhance agent productivity and streamline service processes. The Email Drafter utilizes generative AI to help agents compose contextually appropriate email responses quickly. The Similar Case Recommendation feature employs machine learning to analyze the current case and suggest similar, previously resolved cases. This helps agents find solutions faster by leveraging historical data and knowledge. Both are integral AI capabilities designed to improve resolution times and service consistency.

B. Product Proposal: This functionality is more characteristic of sales or commerce solutions, like SAP Sales Cloud, and is not a standard AI feature for case resolution within SAP Service Cloud Version 2.

D. Validation Rules: These are deterministic, administrator-configured business rules for ensuring data quality and integrity. They operate on predefined logic, not on machine learning or other AI models.

"Generative AI for Email Drafting": "With the generative AI capabilities for email drafting, you can generate new emails or refine existing ones... The AI service uses the case context to generate a relevant draft." (Accessed under the "Intelligent Service" module documentation).

2. SAP Help Portal, SAP Service Cloud Version 2, "Administrator Guide - Validation Rules": This guide describes the configuration and purpose of validation rules.

"About Validation Rules": "You can define validation rules for business objects to prevent users from entering incorrect or incomplete data... A validation rule consists of a condition and a message that is displayed if the condition is met." This description confirms it is a business logic feature, not an AI one.
