Dataverse - Formula Type Column

📌 Dataverse - Formula Type Column

A Formula Type Column in Dataverse allows makers to write Power Fx formulas to compute values automatically. Once saved, Dataverse recalculates the result whenever referenced fields change.

✔️ Supported Power Fx Functions (from official docs)

Formula columns support a subset of Power Fx functions:

  • Math Operators: +, -, *, /, %, ^
  • Logical Operators: And(), Or(), Not(), !, =, >, <, >=, <=
  • String Operators: & (concatenate), in, exactin
  • Text Functions: Upper(), Lower(), Trim(), Left(), Right(), Mid(), Concatenate()
  • Date & Time: Today(), Now(), Year(), Month(), Day(), Hour(), Minute()
  • Logic & Conditions: If(), Switch(), Coalesce(), IsBlank()
  • Conversion: Value(), Text() (with limitations)
  • Record references: LookupColumn.Field (simple parent lookups only)

❗ Not Supported: Filter(), LookUp() on tables, Patch(), Remove(), Collect(), table iteration, and aggregation.

🌟 Advantages

  • ✔️ Uses familiar Power Fx instead of old calculated field designer
  • ✔️ Real-time calculation when dependent fields update
  • ✔️ Cleaner and more powerful than classic calculated columns
  • ✔️ Can reference fields from related lookup (parent) records
  • ✔️ Available in forms, views, Power Apps, Power Automate
  • ✔️ Easy to maintain and version using solutions

⚠️ Limitations / Disadvantages

  • ❌ Cannot query related tables (no Filter(), no LookUp() over tables)
  • ❌ Cannot use functions that change data (Patch, Update, Remove, Collect)
  • ❌ Cannot calculate rollups or aggregate values from child tables
  • ❌ No circular dependencies between formula columns
  • ❌ Sorting disabled in views if formula references lookup fields
  • ❌ Currency type cannot be returned by formula columns
  • ❌ Some Text() conversions are not supported

Calling Microsoft Graph API from Power Automate Using Azure App Services – Step-by-Step Guide

Image
Step 1: You should have an Azure subscription, or if you have access to the Microsoft Entra Admin Center, you can create an app from there. This app can then be used in Power Automate to connect to Microsoft Graph API. Step 2: Click on "New registration" , provide a name for your app, assign the required API permissions (such as Microsoft Graph permissions), and then click "Register" to complete the app registration process. Step 3: After registration, you'll be redirected to the app's overview page. From there, navigate to the API permissions tab and click "Add a permission" to assign the necessary Microsoft Graph API permissions. Step 4: Select Microsoft Graph as the API, and based on your requirements, choose the appropriate permissions. In my case, I selected Application permissions , which do not require user sign-in and are suitable for background services or automation. Step 5: Select the required Microsoft Graph API permissions.

For example, if your API URL is https://graph.microsoft.com/v1.0/users/{email} , the host name will be the highlighted part — graph.microsoft.com . Step 3: Go to the Security tab. Here, you need to select the authentication method. Choose OAuth 2.0 as the authentication type, as shown in the image below. Step 4: Select the Identity Provider as Azure Active Directory . Check the box Enable Service Principal Support . This option allows you to create a connection using a Client ID and Client Secret instead of using the user's own authentication. Next, provide the Client ID , Client Secret , Tenant ID , and other required details as shown in t...
