Hello @v-siky-msft,
My apologies for missing out on that.
I used the formula below to restrict a logged-in user to view their data only.
Filter(dataSource,'Submitted By: '=_myProfile.DisplayName)
I am using a SharePoint list as the data source.
My scenario is, a user submits a request from the app, the request details are sent to the SharePoint list, an automated approval flow is triggered.
The purpose of having the screen/dashboard is to give a user a view of the requests they have made over time and their individual status.
I hope this helps. Thanks.
