LookUp Function for Data Table in CDS?

To give the community a background, I am currently working on customizing the Leave Request template app. Instead of using the OneDrive Excel file for leave banks, I am trying to utilize our SQL Server database which has this information. I pulled that data into the CDS, which I used to populate a Data table in PowerApps.


How can I use the LookUp function so that when users use this application, it will only show their own unique leave banks? I do not want users to be able to see other employee leave banks at all.


So far, the formula I have is: LookUp(BALANCES1S_3, Office365Users.userid(_myProfile.Id));


This seems totally incorrect... where do I plug the correct formula? Is it on the OnVisible for LoginScreen?


Thank you in advance!

Hi @akim91 ,


Please use Filter function instead of Lookup function.

I assume that you will display all the info on a gallery.

Here I have made a test based on SharePoint list, please check it for a reference.

First, create a connection to SharePoint list. There is a column for employee email address.

Then add a gallery control, set its Items property with the following function:


Then it will only display the items related to the current user.

Re: LookUp Function for Data Table in CDS?

hi @v-yamao-msft 


I was wondering if you are familiar with the Leave Request template provided by Microsoft? In the LeaveBalanceScreen, the GalleryLeaveBalance uses the RequesterBalanceCollection with what the template provided. I'm trying to add my own different types of balances (9 different kinds). I was successful in changing the LeaveTypeCollection.


How can I change the RequesterBalanceCollection so that it'll reflect a unique individual's balance? I have a SQL Server table that currently lists every employee we have along with their own balances.
