I am building an app in SharePoint online using PowerApp, I have a dropdown which its data source is from a SharePoint list, it has duplicate data, so I need to get distinct values for the dropdown.

I check PowerApps documentation it has a formula like bellow

Distinct(Employees, Department)

It works if your data connection is from Excel, but if your data connection is from a SharePoint list, I could not figure it out, any help is appreciated

  • In my sharepoint list, I have more than 1500 records. The distinct function only pics up one entry. For Example, 1st 900 records are A 2nd 200 Records are B 3rd 100 Records are C It only shows "A" in my dropdown list and no other option Oct 8 '20 at 6:33

I tried it here and the Distinct function did the job.

Distinct(ListName,ColumnName)

If your list is too large it could take some time to remove the duplicates

No Distinct

With Distinct
