We low-code developers share a common goal: we want to code less but achieve more. For years, extending business logic in the Power Platform meant either diving into full C# plugins or creating complex JavaScript web resources—both requiring pro-code skills that many makers don’t have (or want to develop).

Enter Dataverse Functions. These powerful low-code capabilities let you extend your business logic without writing a single line of C# code. Instead, you use familiar Power Fx expressions to create reusable, performant, and maintainable logic that works across your entire Power Platform ecosystem.

In this blog, I’ll walk you through what Dataverse Functions are, why they matter, and how you can start using them today to level up your Power Platform solutions.

What are Dataverse Functions?

Before we dive deep, let’s clarify the landscape. When we talk about extending Dataverse, we have several options:

• Business Rules – Simple, UI-based rules
• Workflows and Cloud Flows – Process automation
• Calculated Columns – Formula-based fields
• Plugins – Advanced business logic extensions

Plugins come in two flavors:

• Full Code Plugins – Traditional C# plugins requiring Visual Studio, deployment, and maintenance
• Low Code Plugins – What we’re focusing on today

Low-code plugins have evolved into two distinct types:

Automated Plugins: Event-Driven Logic

Triggered automatically when something happens to a Dataverse table (create, update, or delete operations). Think of these as “event-driven” logic that runs whenever data changes.

Functions (formerly Instant Plugins): On-Demand Logic

Triggered on-demand, like custom APIs. These can:

• Accept input parameters
• Process data from multiple tables
• Return custom outputs

The game-changer? You can use them across:

• Canvas Apps
• Model-Driven Apps
• Power Automate flows
• Copilot agents

Why should you care?

Let me break down the benefits:

1. Readable and maintainable

As a low-code developer, I can read and understand Power Fx functions far better than C# plugins.
Refactoring? Easy.
Understanding what a function does six months later? No problem.

2. Performance boost

Functions run server-side in Dataverse, not in your browser.
This means significantly better performance in your Canvas Apps compared to doing complex calculations client-side.

3. Reusability across the platform

Create once, use everywhere:

• Canvas Apps
• Model-Driven Apps
• Power Automate flows
• Copilot agents (yes, really!)

4. No More Duplicate Logic

Stop maintaining the same business rule in five different places.
One function, one source of truth.

Automated Plugins: Event-Driven Logic

These require the Dataverse Accelerator App, which you can install from the Power Platform Admin Center.

Scenario: Date Validation

You’re building a grant management system. Users enter a start date and end date. The end date can’t be before the start date.

Creating the automated plugin:

1. Open the Dataverse Accelerator App

2. Create a new automated plugin
3. Choose your trigger: Create, Update, or Delete
4. Write your Power Fx logic:

If(
    'End Date' < 'Start Date',
    Error({Kind: ErrorKind.Validation, Message: "End date must be after start date"})
)

The magic: This validation now works automatically in both Model-Driven Apps and Canvas Apps. No duplicate code. No forgetting to add validation in one place. Just consistent, reliable business logic.

In Canvas App:

In Model Driven App:

Other ideas:

• Automatic naming conventions: Companies often have naming conventions—document IDs, project codes, etc. Instead of relying on users to follow a manual guide, create an automated plugin that renames records automatically. Example: A record titled “New Brand” is renamed to “BRAND-2025-001-Product Name” based on your company’s conventions. The user doesn’t need to remember the format—it just happens.
• Populate a log row in a separate log table

Functions: On-Demand Power

Unlike automated plugins that react to data changes, functions run when you explicitly call them.

Functions can be added to solutions, meaning you can use pipelines to deploy functions across environments.

Scenario: Shortening titles

// Input: Title (string) // Output: Shorttitle (string)

{Shortentitle: If(Len(Title)>12, Left(Title,10) & "..", Title )}

Using in Canvas Apps

Add the Environment table as a data source

Call your function in a button’s OnSelect:

Set(
    varShortTitle,
    Environment.ShortenTitle({Title: TextInput_ProductTitle.Text}).ShortTitle
)

Using in Power Automate

Add an “Unbound Action” step. Select your function name. Pass the title as input. Receive the shortened version as output

One function. Multiple platforms. Zero duplicate code.

Monitoring and Debugging

Dataverse Functions offer strong debugging features.

Monitor Sessions (Canvas Apps)

Your monitor session shows:

• Inputs sent
• Outputs received
• Execution time
• Errors

A function in a monitoring session:

Trace Logging

Use Trace() statements for in-depth debugging:

Trace("Processing started for: " & Title);
// Your logic here
Trace("Processing completed. Result: " & ShortTitle);

Without Trace()	With Trace()

View trace logs in:

• Dataverse Accelerator App’s Plugin Monitor
• Plugin Trace Viewer in XRM Toolbox
• Power Platform Environment settings app

Important limitations to know

Some things are not (yet) possible with functions:

• ❌ UI Interactions (e.g. navigating screens, showing popups)
• ❌ Limited Connectors (only Microsoft connectors supported)
• ❌ External APIs (limited support)
• ❌ Some Power Fx Functions (e.g. Set(), UpdateContext(), Patch())

Use Power Automate or app logic in these cases.

The Decision Matrix

Conclusion

Dataverse Functions represent a significant leap forward for low-code developers.

You no longer have to choose between simplicity and power, you can have both.

Start small: Pick one business rule you’re duplicating across apps. Convert it to a function. Experience the joy of editing logic once and seeing it update everywhere.

As low-code developers, we now have pro-code capabilities without writing pro-code. We can code less and achieve more.
