"You don't have permission to use this lookup" on a Sharepoint List Person column

[gavinleung]

Hi all, 

I'm building an app (let's call it App A) on Sharepoint List, in which there is a column with Person type. In my app, I added a Connection with Sharepoint, and a data source of the List. All columns are ok, except the Person column. Supposingly I shall be able to search another use of the site in my app, but I have got the captioned error "You don't have persmissions to use this lookup". 

Then I created an app (let's call it App B) directly from the Sharepoint site, I can do what I want to do, ie I can seach another user of the site and input the value into the list thru the app. 

Both apps are leveraging the same list with same set of users. Why is the behaviour different ? And how to fix the issue on App A? 

Many thanks!

Gavin

Hi @gavinleung ,

Could you please share a bit more about your issue?

Do you mean that you could not the LookUp field in your Edit form of your app?

Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned. Please consider remove the SP list data source from your App A, then re-add a new connection to your SP List from your App A, then check if the issue is solved.

If the issue still exists, please consider re-create a new app based on the SP list, check if the issue is fixed.

Best regards,

Thanks. But the issue solved without any reasons or modification on the List...
