description	AL Copilot capability development for Business Central. Use when implementing PromptDialog pages, AI generation features, or integrating with the Copilot toolkit.

Skill: AL Copilot Development (Full Lifecycle)

Purpose

Build AI-powered Copilot experiences in Business Central end-to-end: capability registration, PromptDialog page design, Azure OpenAI generation codeunit, and testing with AI Test Toolkit.

When to Load

This skill should be loaded when:

• A new Copilot/AI feature is being designed or implemented
• A PromptDialog page needs to be created or modified
• Azure OpenAI integration is required (chat completions, JSON mode)
• AI Test Toolkit tests need to be created for a Copilot feature
• Prompt engineering guidance is needed (system/user prompt design)
• A capability needs to be registered in BC's Copilot admin page

Phase 1: Capability Registration

Objects Required

1. Enum Extension — extend "Copilot Capability" to register your feature
2. Install Codeunit — register the capability on app install
3. Isolated Storage Wrapper — manage Azure OpenAI secrets securely

Pattern: Enum Extension

namespace Contoso.CopilotFeatures;

using System.AI;

enumextension 50100 "Contoso Copilot Capabilities" extends "Copilot Capability"
{
    value(50100; "Sales Forecasting")
    {
        Caption = 'Sales Forecasting with Copilot';
    }
}

Pattern: Install Codeunit

namespace Contoso.CopilotFeatures;

using System.AI;

codeunit 50100 "Contoso Copilot Setup"
{
    Subtype = Install;
    InherentEntitlements = X;
    InherentPermissions = X;
    Access = Internal;

    trigger OnInstallAppPerDatabase()
    begin
        RegisterCapability();
    end;

    local procedure RegisterCapability()
    var
        CopilotCapability: Codeunit "Copilot Capability";
        LearnMoreUrlTxt: Label 'https://learn.microsoft.com/dynamics365/business-central/', Locked = true;
    begin
        if not CopilotCapability.IsCapabilityRegistered(
            Enum::"Copilot Capability"::"Sales Forecasting") then
            CopilotCapability.RegisterCapability(
                Enum::"Copilot Capability"::"Sales Forecasting",
                Enum::"Copilot Availability"::Preview,
                LearnMoreUrlTxt);
    end;
}

Availability options: Preview (opt-in), GA (general availability).

After publishing, verify the capability appears in BC: search "Copilot & AI Capabilities" page.

Pattern: Isolated Storage Wrapper (Secrets)

codeunit 50101 "Contoso Isolated Storage"
{
    Access = Internal;

    procedure GetSecretKey(): SecretText
    var
        Secret: Text;
    begin
        if IsolatedStorage.Get('AzureOpenAIKey', DataScope::Module, Secret) then
            exit(Secret);
        Error('Azure OpenAI key not configured.');
    end;

    procedure SetSecretKey(NewKey: SecretText)
    begin
        IsolatedStorage.Set('AzureOpenAIKey', NewKey, DataScope::Module);
    end;

    procedure GetEndpoint(): Text
    var
        Endpoint: Text;
    begin
        if IsolatedStorage.Get('AzureOpenAIEndpoint', DataScope::Module, Endpoint) then
            exit(Endpoint);
        Error('Azure OpenAI endpoint not configured.');
    end;

    procedure SetEndpoint(NewEndpoint: Text)
    begin
        IsolatedStorage.Set('AzureOpenAIEndpoint', NewEndpoint, DataScope::Module);
    end;

    procedure GetDeployment(): Text
    var
        Deployment: Text;
    begin
        if IsolatedStorage.Get('AzureOpenAIDeployment', DataScope::Module, Deployment) then
            exit(Deployment);
        exit('gpt-4o');   // default model
    end;

    procedure SetDeployment(NewDeployment: Text)
    begin
        IsolatedStorage.Set('AzureOpenAIDeployment', NewDeployment, DataScope::Module);
    end;
}

Production vs Development:

• Development: configure own Azure OpenAI credentials via SetSecretKey/SetEndpoint/SetDeployment
• Production: use SetManagedResourceAuthorization (Microsoft-managed, no secrets needed)

Phase 2: PromptDialog Page

Page Areas

Area	Purpose	Contains
PromptOptions	User settings/filters	Option/Enum fields only
Prompt	User text input	Free-text field with InstructionalText
Content	AI output display	Text field or part subpage with results
PromptGuide (actions)	Example prompts	Actions that pre-fill the Prompt field
SystemActions (actions)	Generate / OK / Cancel	systemaction(Generate), systemaction(OK), etc.

PromptMode Options

Mode	Behavior	Use when
Prompt	Shows input first, user clicks Generate	User needs to provide context
Generate	Auto-runs generation when page opens	Context is pre-filled from calling page
Content	Shows content only, no generation	Displaying previously generated results

Pattern: Complete PromptDialog Page

namespace Contoso.CopilotFeatures;

using System.AI;

page 50110 "Contoso Sales Forecast Copilot"
{
    PageType = PromptDialog;
    Extensible = false;

                ApplicationArea = All;
                Caption = 'Forecast Period';

            }
        }

        area(Prompt)

                ApplicationArea = All;
                InstructionalText = 'Describe what you want to forecast (e.g., "top 10 items for next quarter")';

                trigger OnValidate()
                begin
                    CurrPage.Update();
                end;
            }
        }

                MultiLine = true;

            }

        area(PromptGuide)
        {
            action(ExampleTopItems)
            {

    }

    trigger OnQueryClosePage(CloseAction: Action): Boolean
    begin
        if CloseAction = CloseAction::OK then
            ApplySuggestions();
    end;

    local procedure RunGeneration()
    var
        GenerationCU: Codeunit "Contoso Forecast Generation";
    begin
        AIResponseText := '';
        GenerationCU.SetUserPrompt(UserPromptText);
        GenerationCU.SetPeriod(SelectedPeriod);

        if GenerationCU.Run() then
            AIResponseText := GenerationCU.GetCompletionResult()
        else
            Error('Generation failed: %1', GetLastErrorText());

        CurrPage.Update(false);

        AIResponseText: Text;
        SelectedPeriod: Option "Next Month","Next Quarter","Next Year";
        ContextItemCategory: Code[20];
}

Pattern: Temporary Table for Structured Output

When AI returns a list of proposals (not just text), use a temporary table:

table 50110 "Contoso Forecast Proposal"
{
    TableType = Temporary;
    Caption = 'Forecast Proposal';

    fields
    {
        field(1; "Entry No."; Integer) { AutoIncrement = true; }
        field(10; "Item No."; Code[20]) { Caption = 'Item No.'; }
        field(20; Description; Text[100]) { Caption = 'Description'; }
        field(30; "Forecast Qty"; Decimal) { Caption = 'Forecast Quantity'; }
        field(40; Explanation; Text[250]) { Caption = 'AI Explanation'; }
        field(50; "Confidence Score"; Decimal) { Caption = 'Confidence'; MinValue = 0; MaxValue = 1; }
    }

    keys
    {
        key(PK; "Entry No.") { Clustered = true; }
    }
}

Display via a ListPart subpage linked by part() in the Content area.

Prompt Engineering Guidelines

System prompt structure:

1. Role — who the AI is ("sales forecasting expert")
2. Task — what it must do ("analyze data, predict demand")
3. Rules — constraints ("only use provided data", "no hallucinated IDs")
4. Output format — exact JSON schema with field descriptions

User prompt structure:

1. Context data — BC records formatted as text (items, customers, history)
2. Parameters — user-selected options (period, filters)
3. Request — the user's free-text input

Key parameters:

Parameter	Value	Effect
Temperature	0	Deterministic, consistent results
Temperature	0.7	Creative, varied results
MaxTokens	2500	Limits response length
SetJsonMode(true)	—	Forces valid JSON output

Phase 4: Testing with AI Test Toolkit

Dependency Setup

Add to Test app app.json:

{
    "dependencies": [
        {
            "id": "2156302a-872f-4568-be0b-60968696f0d5",
            "publisher": "Microsoft",
            "name": "AI Test Toolkit",
            "version": "26.0.0.0"
        }
    ]
}

Pattern: Copilot Test Codeunit

namespace Contoso.CopilotFeatures.Tests;

using System.TestLibraries.AI;

codeunit 50200 "Contoso Forecast Copilot Tests"
{
    Subtype = Test;
    TestPermissions = Disabled;

    var
        Assert: Codeunit Assert;

    // --- Happy Path ---

    [Test]
    procedure Generate_ValidInput_ReturnsStructuredJSON()

        // [SCENARIO] Valid prompt returns non-empty structured proposals
        Initialize();
        CreateTestSalesData();

        GenCU.SetUserPrompt('Top 5 selling items next quarter');
        Assert.IsTrue(GenCU.Run(), 'Generation should succeed');
        GenCU.GetResult(TmpResult);

        // [THEN] Results are not empty and fields are populated

        Assert.IsTrue(
            (TmpResult."Confidence Score" >= 0) and (TmpResult."Confidence Score" <= 1),
            'Confidence must be 0..1');
    end;

    // --- AI Test Toolkit Dataset Test ---

    [Test]
    procedure Generate_AITDataset_OutputMatchesSchema()

AI Test Toolkit Workflow

1. Open BC → search "AI Test Suite"
2. Create a new test suite for your Copilot feature
3. Define input datasets — each row is a test prompt + expected behavior description
4. Run the suite — each input is passed via AITTestContext.GetInput()
5. Validate output structure (JSON schema), NOT exact text (AI varies)
6. Use AITTestContext.SetTestOutput() to log results for manual review

Key testing principles for AI features:

• Assert structure and constraints, not exact wording
• Use Temperature = 0 for consistency tests
• Test edge cases: empty input, long input, special characters, no data
• Test error codes: 402 (quota), 429 (rate limit), 503 (unavailable)
• Test that suggested IDs actually exist in BC data (no hallucinations)

Workflow

Step 1: Design Copilot Experience

Define before coding:

1. User problem — what task does this Copilot help with?
2. PromptMode — Prompt (user types) vs Generate (auto-run)?
3. Input — free text, options, context from calling page?
4. Output — simple text or structured proposals (temp table + subpage)?
5. AI model — Temperature (deterministic vs creative), MaxTokens

Step 2: Implement (Phase 1 → Phase 3)

1. Register capability (Phase 1: enum + install codeunit)
2. Create PromptDialog page (Phase 2: areas, system actions, prompt guide)
3. Create generation codeunit (Phase 3: Azure OpenAI + JSON parsing)
4. Build: Bash: al compile (al workspace compile for a multi-project workspace)

Step 3: Test (Phase 4)

1. Add AI Test Toolkit dependency to Test app
2. Create test codeunit with happy path, edge cases, consistency, performance
3. Create AI Test Suite dataset in BC for systematic prompt evaluation
4. Run tests and iterate on prompts

Step 4: Responsible AI Review

Before shipping:

• User transparency — users know they're interacting with AI
• Content filtering — no raw AI output without validation
• Data privacy — no sensitive data in prompts without sanitization
• Feedback — users can accept/reject AI suggestions (OK/Cancel)
• Error handling — graceful handling of all Azure OpenAI error codes

Constraints

• Do NOT expose raw AI responses without validation — always parse and verify structure
• Do NOT include sensitive customer data in prompts without sanitization
• Do NOT deploy Copilot features without Responsible AI compliance review
• Do NOT skip AI Test Toolkit testing — every Copilot feature MUST have test coverage
• Do NOT use deprecated SetAuthorization in production — use SetManagedResourceAuthorization
• Do NOT hardcode Azure OpenAI credentials — always use IsolatedStorage
