Step-by-Step Fabric Data Agent Setup

Prerequisites for Data Agent Creation

  • Required Fabric Capacity: F2 or higher (or Premium P1+)
  • Required Fabric Workspace: Admin or Member role
  • Required At least one data source: Lakehouse, Warehouse, KQL, or Power BI Model
  • Recommended Data Documentation: Column descriptions, business glossary terms
  • Recommended Example Q&A: Sample questions and expected answers for Data Agent fine-tuning

Data Agent Creation Steps

1

Open Your Workspace

Navigate to your Fabric workspace (minimum F2 capacity). Ensure you have Admin or Member permissions for Data Agent creation.

2

Create New Fabric Data Agent

Click + New Item → Select Fabric Data Agent. Give your Data Agent a meaningful name (e.g., “Sales Analytics Agent”).

3

Configure Data Agent Sources

Select up to 5 sources for your Data Agent. For each source, choose specific tables or entire databases. Provide detailed descriptions for each table and important columns—this significantly improves Data Agent accuracy.

4

Define Data Agent Instructions

Write clear instructions for how your Data Agent should interpret user prompts:

Example Data Agent Instructions: • “For revenue questions, prioritize the Warehouse Sales table over Lakehouse raw data.” • “Always include regional breakdowns when available.” • “Convert fiscal months to calendar dates for user clarity.” • “Flag any results with null values for investigation.”
5

Add Example Q&A Pairs for Data Agent

Seed your Data Agent with 5-10 realistic business questions and correct answers. For example:

  • “Show total revenue by product category for Q4 2024”
  • “Which regions had negative YoY growth?”
  • “List top 10 customers by lifetime value”
6

Test & Validate Your Data Agent

Use the chat interface to test real prompts. Moreover, try synonyms, complex queries, and edge cases. Refine Data Agent instructions based on results.

7

Configure Data Agent Permissions

Set role-based access for your Data Agent. Decide who can use the Data Agent and what data sources they can access.

8

Publish & Deploy Data Agent

Publish your Data Agent. Share it in your workspace, Teams, Copilot Studio, or embed in custom apps.

9

Monitor & Iterate Data Agent

Check usage in Capacity Metrics. Additionally, review user feedback, add new data sources or refine Data Agent instructions quarterly.

Common Data Agent Pitfall: Skipping data descriptions. Column metadata (“Sales” = total revenue after discounts) dramatically improves Data Agent accuracy. Invest time here upfront.

Fabric Data Agent Prompt Engineering & Instructions

The quality of Data Agent instructions directly impacts answer accuracy. Specifically, here’s how to craft powerful, unambiguous instructions.

Best Practices for Data Agent Instructions

Define Data Logic Explicitly

Your Data Agent needs clarity: “Revenue = Qty × Price – Discounts. Exclude canceled orders.”

List Synonyms & Abbreviations

Help your Data Agent understand: “SKU = Stock Keeping Unit. Product ID = internal identifier.”

Prioritize Data Agent Sources

Guide Data Agent decisions: “For real-time metrics, use KQL database. For historical trends, use Warehouse.”

Enforce Data Agent Compliance

Protect sensitive data: “Never expose PII. Flag results with sensitive customer data.”

Example: Financial Fabric Data Agent Instructions

# Sales & Revenue Data Agent Instructions## Data Definitions – GROSS_REVENUE: Sum of all customer invoices – NET_REVENUE: Gross revenue minus returns, cancellations – MARGIN: (Net Revenue – COGS) / Net Revenue * 100 – REGION: Geographic area (North, South, East, West)## Data Agent Prioritization Rules 1. For current month data: Use Lakehouse (real-time) 2. For historical trends (>3 months): Use Warehouse (optimized) 3. For customer metrics: Use Power BI Model (pre-aggregated)## Synonyms for Data Agent – “Revenue” = Net Revenue – “Profit” = Gross Margin – “Orders” = Transactions – “Customers” = Unique Accounts## Data Agent Constraints – Always include confidence level (high/medium/low) – Flag results where sample size < 100 - Never expose customer PII (names, emails, phones) - Round percentages to 1 decimal place

Example: Data Agent Q&A Training Data

Q: “How did Q4 revenue compare to Q3?” A: Q4 Net Revenue: $2.3M | Q3 Net Revenue: $1.8M | Growth: +27.8%Q: “Which regions are underperforming?” A: East region (87% of target), South region (92% of target) Recommendation: Review pricing and promotion strategy.Q: “Top 5 products by margin” A: [Product names and margin percentages] Note: Excludes products with <50 units sold.
Pro Tip: Advanced prompt engineering techniques enhance Data Agent performance. Apply those concepts to Data Agent instructions for maximum accuracy.

Fabric Data Agent Deployment & Rollout Strategy

Phased Data Agent Rollout Approach

1

Pilot Phase

Deploy your Data Agent to 5-10 power users. Gather feedback on accuracy and usability. Refine Data Agent instructions.

2

Department Scale

Expand your Data Agent to a single department (Sales, Finance, Ops). Monitor capacity and cost carefully.

3

Organization-Wide

Roll out your Data Agent to all teams. Establish governance policies and support processes.

Data Agent Transition Guidelines

  • Announce Early: Let teams know about the Data Agent 2-3 weeks before launch. Show demo videos.
  • Provide Data Agent Training: Host 30-minute sessions on “How to Ask Data Agent Questions” and common use cases.
  • Create FAQ Document: Capture most-asked Data Agent questions and their correct format.

  • Triggered Data Agent Actions: Data Agent detects anomaly → Copilot automatically creates support ticket and notifies manager.
  • Multi-step Data Agent Flows: User requests “Show revenue trend” → Data Agent answers → User asks “Generate forecast” → Another Data Agent or model handles it.
  • Data Agent Context Passing: Conversation history flows between Data Agent and copilot, maintaining context across interactions.
Official Guide: See Microsoft Learn documentation for step-by-step Fabric Data Agent integration instructions and code examples.

Fabric Data Agent Security & Governance

Fabric Data Agents enforce security at every layer. Understanding these mechanisms ensures compliance and protects sensitive data.

Security Layers in Data Agents

Row-Level Security (RLS)

Data Agents enforce RLS filters defined in source tables. Users see only data they’re authorized to access.

Object-Level Security

Users can only query tables that they have permission to access. Hidden tables are invisible to Data Agents.

Workspace Isolation

Data Agents operate within workspace boundaries. Cross-workspace queries require explicit shortcuts and permissions.

Audit Logging

Every query, Data Agent answer, and permission check is logged. Full traceability for compliance audits.

Fabric Data Agent Governance Best Practices

  • Data Classification: Tag sensitive tables as “Confidential” or “Internal Only.” Restrict Data Agent access accordingly.
  • Role-Based Data Agent Access: Only Analysts can create Data Agents; Managers can view shared agents; Executives get read-only.
  • Quarterly Data Agent Reviews: Audit Data Agent usage, validate RLS effectiveness, review access changes.
  • Data Masking Strategy: For PII (SSN, email, phone), apply masking in source tables or Data Agent instructions.
  • Conversation Retention Policy: Define how long Data Agent conversation history is retained (default 90 days).
Critical: Test RLS thoroughly before deploying Data Agents to production. Misconfigured row filters can expose sensitive data. Cloud Security Tips provide hardening strategies.

Fabric Data Agent Performance & Capacity Management

Data Agent Token Consumption Model

Notably, Data Agent costs are based on token consumption (language model input/output). Understanding this model optimizes costs:

Token TypeCost per 1000 TokensTypical Data Agent Usage
Input Tokens~$0.005 (100 CU)User question, Data Agent instructions, context
Output Tokens~$0.015 (400 CU)Data Agent response, data results

Data Agent Cost Optimization Strategies

  • Pre-aggregate data: Use Power BI Models with pre-calculated measures. Data Agents reduce data retrieval size and output tokens.
  • Limit Data Agent source scope: Connect only relevant tables to each Data Agent, not entire databases.
  • Caching with Data Agents: Fabric caches repeated queries, reducing Data Agent token reuse cost by up to 90%.
  • Monitor Data Agent per-user: Track Data Agent usage by department and user. Identify and optimize heavy users.
Capacity Planning: Use Fabric Pricing Calculator to estimate monthly Data Agent costs based on expected query volume and token consumption.
