Delegable Queries in PowerApps Canvas Apps

Let the Data Source Do the Heavy Lifting: Delegable Queries in PowerApps Canvas Apps

As a PowerApps developer, I’ve come across many performance and functionality issues that stem not from bad intentions, but from a lack of understanding of how data queries work under the hood. One of the most critical – and often misunderstood – aspects of building performant and scalable apps is delegation.

In this post, I want to deep dive into:

• Why I’m writing about delegable queries
• The issues non-delegable queries cause
• Why these issues exist
• How to fix or work around them
• Best practices to keep your apps fast, efficient, and robust

Why I’m Writing About Delegable Queries

When building Canvas Apps that connect to large data sources like SharePoint, Dataverse, or SQL Server, I’ve noticed apps slowing down or failing to return expected results. After some investigation, the root cause is often the same: non-delegable queries.

Too many makers overlook this constraint or don't fully understand its impact. I’m writing this to help other makers avoid the pitfalls I encountered and to promote sustainable development practices within the Power Platform community.

What is Delegation?

In PowerApps, delegation refers to the ability of the app to pass the query to the data source for processing. When a query is delegable, only the result is returned – saving bandwidth, improving performance, and avoiding local processing limits.

Non-delegable queries, on the other hand, mean the app pulls the data into memory (default: first 500 records, max: 2000) and then applies filters or operations locally. This not only limits results but can dramatically reduce performance and scalability.

Are Delegable Queries Part of Power Fx?

Yes — delegable queries are written using Power Fx, the low-code formula language of Canvas Apps. But here's the catch:

Not all Power Fx functions are delegable.

Let’s break it down:

• Power Fx is used to express logic in Canvas Apps — filtering, sorting, updating, etc.
• But for a query to be delegable, PowerApps must be able to convert that Power Fx expression into a query that the backend system (like SQL or SharePoint) understands.

✅ Delegable Power Fx Example (SharePoint):

Filter(Employees, Department = "HR")

This uses delegable functions and operators — processed server-side.

❌ Non-Delegable Power Fx Example:

Filter(Employees, StartsWith(Name, "S"))

Because StartsWith isn't delegable in SharePoint, possibly missing many matching entries.

The Issue: Why Non-Delegable Queries Are a Problem

Let’s say you have a SharePoint list with 50,000 records and you write this formula:

Filter(MyList, StartsWith(Title, "S"))

This will not return all the records starting with "A". It will only apply to the first 500 or 2000 rows, depending on your app settings, because StartsWith is not delegable for SharePoint. That means records beyond the delegation limit are not evaluated – potentially causing missing data and misleading outputs.

Symptoms of Non-Delegable Queries:

• Partial results
• "Delegation warning" yellow triangle in the formula bar
• Slower performance
• Data inconsistencies
• Errors in large data sets

Why Does This Happen?

PowerApps is a low-code platform that connects to a variety of data sources, each with its own capabilities. Microsoft must abstract the query language (like OData, T-SQL) to Power Fx.

But not all Power Fx functions can be translated into native data source queries. If PowerApps can’t delegate a function, it falls back on retrieving data locally – up to the configured delegation limit.

Each connector has a documented set of delegable functions and operators, which you can refer to on Microsoft Learn.

Fixes and Workarounds

While not all functions are delegable, there are techniques to work around these limitations.

1. Use Delegable Functions When Possible

Learn which functions are delegable for your data source. Common ones:

• Filter
• Search
• LookUp
• SortByColumns

Avoid:

• StartsWith, Mid, Len, Left (for SharePoint)
• Complex nested logic

Instead of:

Filter(MyList, StartsWith(Title, "A"))

Use:

Filter(MyList, Title >= "A" && Title < "B")

2. Index Your Columns

Especially for SharePoint, indexing columns used in filtering significantly improves performance and helps delegation succeed.

3. Use Views or Stored Procedures

If using SQL Server or Dataverse, offload complex queries into views or stored procedures and call them from your app.

4. Combine Client-Side and Server-Side Filtering

When full delegation isn’t possible, use delegable filtering first, then a local filter:

Filter(
    Filter(MyList, Title >= "A" && Title < "B"), 
    AnotherClientSideFilter
)

5. Paginate or Virtualize Large Datasets

Use techniques like pagination, galleries with lazy loading, or loading records in chunks via Concurrent or With constructs.

Best Practices for Delegable Queries in PowerApps

• Always check for delegation warnings. Don't ignore the yellow triangle – it's there for a reason.
• Keep delegation in mind during design. Plan app logic around what your data source supports.
• Set realistic delegation limits. Increase the limit from 500 to 2000 only if necessary – but don’t rely on it.
• Minimize on-the-fly filtering on non-indexed columns.
• Test with production-sized data.
• Educate your team. Make delegation part of your code review or governance checklist.
• Refer to the Delegation Cheat Sheet. Microsoft maintains updated lists for each connector’s delegable functions.

Conclusion

Delegation is not just a PowerApps quirk – it’s a fundamental performance principle. Think of it as letting the database do what it’s good at: filtering, sorting, searching. Your app should only worry about displaying the final results.

By mastering delegation, you’ll:

• Improve app speed
• Prevent missing data
• Reduce support tickets
• Build scalable enterprise-grade apps

Learn what’s delegable:

• Watch for the yellow warning triangle in the formula bar
• Reference Microsoft’s docs:

Power Apps and Dynamics 365 Licensing

🔹 Dynamics 365 and Power Platform Licensing – Detailed Breakdown

I will be honest — Microsoft licensing wasn’t always my favorite topic. Like many Power Apps developers, I focused on building solutions, not figuring out who’s allowed to use what.

A few months ago, I was leading a Power Apps project, during a project review meeting, questions started piling up:

• “Can’t we just give everyone Power Apps licenses instead of Dynamics licenses to save cost?”
• “Can a Team Member run this flow?”
• “Is this Dataverse table covered by our license?”
• “Do we need a Sales license just to store contact data?”

That’s why I’m writing this post. I’m writing this post because I’ve seen firsthand how confusing licensing can be. I’ve seen organizations spend weeks in building apps, and realize later that users aren’t even licensed to run them. Others overspend on licenses just to be safe, or under-license out of ignorance. In this blog i tried to break down the licensing into plain English — grounded in real project experience — so you can make decisions right from the start.

🔹 1. Power Apps Per User License: What Can You Do?

If a user has a Power Apps per user license, they can:

• Build and run unlimited custom apps using Dataverse.
• Use premium connectors (like SQL Server, Dataverse, HTTP, etc.).
• Create workflows using Power Automate.

Important note: If you're building apps that use data from the same tables used by D365 Sales, that's fine — as long as you don’t use the full Sales app experience.

Dynamics 365 Sales is a packaged solution. So while Power Apps lets you read/write Sales data through your own custom apps, it does not give access to the full Sales interface or built-in processes.

✅ OK: Custom canvas or model-driven apps using Dataverse.
❌ Not OK: Using the full D365 Sales app UI or mimicking its full functionality.

🔹 2. Dynamics 365 Sales Enterprise License: What’s Included?

The D365 Sales Enterprise license gives users:

• Full use of the packaged Sales app.
• Rights to build and use custom Power Apps.
• Access to Power Automate and premium connectors.

This means users can build apps, automate flows, and extend the Sales module — all without needing a separate Power Apps license.

🔹 3. D365 Customer Service Enterprise: Same Rules Apply

The Customer Service Enterprise license works the same way as Sales Enterprise.

Users can:

• Use the full Customer Service app.
• Build custom apps and flows for service-related tasks.
• Access Dataverse and premium connectors.

No additional licensing needed for building extended solutions here either.

🔹 4. Dynamics 365 Team Member License: What Can’t You Do?

This is a lightweight license meant for basic tasks like:

• Viewing data
• Entering notes or time entries
• Reading dashboards

However, users with this license cannot:

• ❌ Build or run custom apps that access restricted tables (like Opportunity or Case).
• ❌ Use Power Automate flows with premium connectors.
• ❌ Run apps that replicate full D365 Sales/Service features.

Bottom line: This is for occasional users only — not for app builders or power users.

✅ Quick Summary Table

User License	Can Use Custom Apps?	Can Use D365 Apps?	Use Premium Connectors?	Custom Flows Allowed?
Power Apps Per User	✅ Yes, for custom data	❌ No, for full D365 apps	✅ Yes	✅ Yes
D365 Sales Enterprise	✅ Yes	✅ Yes	✅ Yes	✅ Yes
D365 Customer Service	✅ Yes	✅ Yes	✅ Yes	✅ Yes
D365 Team Member	⚠️ Limited	⚠️ Limited	❌ No	⚠️ Very Limited

Fixing the “No Name” Issue When Setting RegardingObjectId in Dataverse Plugins

When building plugins for Microsoft Dataverse, setting lookup fields like regardingobjectid can be tricky—especially with polymorphic lookups. A common issue developers face is seeing “No Name” in the UI even after setting the lookup value. This blog post explores why this happens and how to handle it properly in your plugin code.

The Problem

Suppose you’re assigning a broker to an Appointment record using a plugin. Your code might look like this:

EntityReference brokerRef = (EntityReference)appointmentEntity["crm_broker"];
appointmentEntity["regardingobjectid"] = new EntityReference(brokerRef.LogicalName, brokerRef.Id);

This sets the lookup correctly in terms of entity and ID, but the regardingobjectid shows up as “No Name” in the UI. Why?

The Cause

The EntityReference object also has a Name property, which is what the UI uses to display the label. In a Pre-Operation plugin, the record isn’t fully committed to the database yet, so Dataverse doesn’t resolve or populate this display name automatically for polymorphic lookups like regardingobjectid.

The Fix

To resolve this, explicitly retrieve the name, and all dependent attributes of the target record and assign it when setting the EntityReference:

EntityReference brokerRef = (EntityReference)appointmentEntity["crm_broker"];
Entity broker = service.Retrieve(brokerRef.LogicalName, brokerRef.Id, new ColumnSet("name"));
string brokerName = broker.GetAttributeValue<string>("name");

appointmentEntity["regardingobjectid"] = new EntityReference(brokerRef.LogicalName, brokerRef.Id)
{
    Name = brokerName
};

Why This Works

• UI rendering depends on the Name property of the lookup reference. If it's missing, the form defaults to displaying "No Name".
• In the Pre-Operation stage, the record and its references haven’t been persisted yet—so polymorphic lookups can't be resolved unless you provide the metadata yourself.
• By manually setting the Name, you ensure the UI has what it needs to render the label correctly.

Additional Tips

• ✅ Stage Awareness: Consider setting the regardingobjectid in a Post-Operation plugin if possible. This guarantees the record is committed and lookups are more reliably resolved.
• ✅ Check Permissions: Ensure your plugin has adequate permissions to retrieve the broker entity’s name field.
• ✅ Avoid UI Confusion: Even after correcting the plugin, browser caching or form loading issues might delay UI updates. Refresh the form or clear the cache to see changes.

Final Thoughts

Handling lookup fields—especially polymorphic ones like regardingobjectid—requires attention to detail. By explicitly setting the Name in your EntityReference, you ensure smoother user experiences and cleaner data presentation.

Power Apps’ Ungroup(): Combining Tables for Dynamic Dropdowns

In Power Apps, building dynamic, user-friendly dropdowns often involves fetching distinct values from a data source and then prepending or appending custom options. A common challenge arises when you want to merge literal records (like an “All” choice) with a result set returned by functions such as Distinct(). In this post, we’ll deep-dive into the Ungroup() function and show you how it elegantly solves this problem—using the real-world example of a visitor check-in app where we need to list hosts in a dropdown.

📋 The Scenario: Visitor Management App

Imagine you’ve built a Canvas App called Visitor Check-In. Your SharePoint list, Visitor Records, tracks each visitor’s details, including a Person or Group column named Host.

On your front-desk interface, you want a dropdown that lets staff:

1. Select “All” (to see every visitor for all hosts) or
2. Pick a specific host’s name (to filter the gallery by that host).

Fetching the distinct host names is simple:

Sort(
    Distinct('Visitor Records', Host.DisplayName),
    Value,
    SortOrder.Ascending
)

But how do you add an “All” option at the top of those results?

❌ Why Common Approaches Fail

Many developers try:

[ {Value: "All"} ] & Sort(
    Distinct('Visitor Records', Host.DisplayName),
    Value,
    SortOrder.Ascending
)

Table({Value: "All"}) & Sort(
    Distinct('Visitor Records', Host.DisplayName),
    Value,
    SortOrder.Ascending
)

Both produce schema mismatches or invalid-argument errors. Power Apps expects each side of the & operator to be a table with the same structure (same column names and types). Distinct() returns a one-column table (Value), but Table({Value:"All"}) is a distinct construct that doesn’t line up neatly.

✅ The Ungroup() Solution

The trick is to use Table() to create a nested table that contains both the literal record and the result of Distinct(), then flatten that nested table back into a single column using Ungroup(). Here’s the magic formula:

Ungroup(
    Table(
      { Value: "All" },
      Sort(
        Distinct('Visitor Records', Host.DisplayName),
        Value,
        SortOrder.Ascending
      )
    ),
    Value
)

Let’s break down each component of this code:

1. Distinct('Visitor Records', Host.DisplayName)
   • Purpose: Extract unique host names from the Visitor Records list.
   • Benefit: Ensures duplicate host entries don't clutter the dropdown.
2. Sort(..., Value, SortOrder.Ascending)
   • Purpose: Sorts the distinct host names in alphabetical order.
   • Benefit: Enhances user experience by providing an intuitive, well-ordered list.
3. Table({ Value: "All" }, ...)
   • Purpose: Manually creates a table with a single record for the option "All" and concatenates it with the sorted distinct host names.
   • Benefit: Provides a universal option that allows users to bypass filtering by a specific host.
4. Ungroup(..., Value)
   • Purpose: Flattens the combined table into a single-column table by merging all records.
   • Benefit: Ensures the final output is simple and can be easily bound to dropdown controls without any nesting issues.

🛠 Step-by-Step Implementation

1. Insert a Dropdown on your Canvas screen and set its Items property to the Ungroup() formula above.

2. Set the dropdown’s Default property to "All".

3. Reference Dropdown1.Selected.Value when filtering your gallery:

Filter(
    'Visitor Records',
    Dropdown1.Selected.Value = "All"
      || Host.DisplayName = Dropdown1.Selected.Value
)

Why and When Should You Use Ungroup?

• Flattening Complex Data Structures: When data sources are combined or grouped, columns may end up containing nested tables. Ungroup removes that extra layer, delivering a simplified, single‐level table.
• Enhancing Control Binding: Many PowerApps controls expect a flat table. By using Ungroup, you ensure that these controls receive data in the proper format, avoiding errors or unexpected behaviors.
• Improved Data Manipulation: Once flattened, the data is much easier to filter, sort, and manipulate. This leads to cleaner and more maintainable formulas in your app.

Benefits of Using Ungroup in Our Scenario

• Clean Data Presentation: The final output is a neatly flattened, single-column table containing both the manual "All" record and the dynamically sourced host names—ideal for use in dropdowns.
• Ease of Use: Flattening the nested table avoids the need for additional parsing or custom functions.
• Flexibility: This method allows you to easily include more custom records without reengineering the data structure.

Conclusion

The Ungroup function is invaluable when developing in PowerApps, particularly in scenarios like our Visitor Pre-Registration and Check-In System where merging static and dynamic data is essential. By using Ungroup to flatten a nested table, we can ensure that our enhancements—such as dropdown controls for filtering—are robust, user-friendly, and maintainable.

Whether you’re building a visitor management solution or any other application that deals with composite data sources, mastering Ungroup can significantly streamline your development process. Happy PowerApping!
