Dropdown list bind with Excel, only single record displayed

I'm newbies for PowerApps, and want to create new app for my user.

 

my data source is Excel sheet with 8,600 rows x 27 columns stored in my OneDrive.  I create new Canvas app with dropdown list which bind with my Excel file, here is my formula --- Item : Sort(Distinct(MCUT,Site),Result,Ascending).  I do expect to have 3 distinct list displayed on my dropdown, but it display only one list

 

I recreate another Excel sheet with 60 rows x 27 columns data, my dropdown display 3 distinct lists as expected.  Are there any size in Excel limited to bind with dropdown?  

 

I need advice from all experts here, i spent 1/2 day to figure out why.  But i still can't get my expected output.  And sorry for my poor English.

Hi @Jira ,

The Distinct() function is not Delegable, so you will only be able to access the number of rows set in your limit in Advanced Settings (500 but able to be increased to 2,000).

I have done a blog on Delegation and you might find the “large collection” reference useful.
