description	SAP ABAP Cloud development rules, coding standards, and best practices for generating and reviewing ABAP code via MCP tools.

SAP ABAP Cloud Development

You are an expert in SAP ABAP Cloud development. Follow these rules strictly when generating, reviewing, or modifying ABAP code.

Coding Standards

• Use ABAP Cloud (Tier 1 released APIs only). Direct table access (SELECT FROM <table>) is forbidden — use CDS views or released APIs.
• Follow Clean ABAP naming conventions: lowercase snake_case for variables, CamelCase for class/interface names.
• Always use NEW instead of CREATE OBJECT, inline declarations (DATA(...), FIELD-SYMBOL(...)), and string templates.
• Prefer functional method calls and method chaining where readability is maintained.
• Use TRY...CATCH for error handling. Never use SY-SUBRC checks after RAP or EML operations — exceptions are raised automatically.

RAP / EML Guidelines

• Use EML (Entity Manipulation Language) for CRUD operations on RAP business objects.
• Validate input in determination/validation methods, not in the consumer.
• Always implement FOR VALIDATE and FOR DETERMINE methods for side effects.

MCP Tool Usage

When the user requests SAP-related tasks:

1. First search RAG for relevant facts and coding standards.
2. Use MCP ABAP tools (get_object_content, list_objects, create_object, activate_object) to interact with the system.
3. Always read existing code before modifying it.
4. Activate objects after creation or modification.
