Filter a galley based on a column from other list

[Miguel_MESP]

Hello all,

I have a screen on a app where I present vehicle requests presented on a sharepoint list called "Vehicles". Then I have another list called "CheckIns" where I place the date time of check In.

I'm creating a screen where people will do check in and check out of the vehicle and what I want to do is to filter that gallery only for the requests who are blank on the checkOut column on CheckIns list.

I'm trying with look up but doesn't work:

Filter(Request, LookUp(CheckIns, IsBlank(CheckOut)) or Filter(Request, LookUp(CheckIns, CheckOut = "")

Some more hints to help visualize:

This is my Request list:

This is my CheckIns List: Request ID is a lookup column to ID from Request list

This is my gallery example:

Thanks in advance!

Hi @Miguel_MESP ,

Something like this should work - assuming these are the matching columns

Filter(
   AddColumns(
      Request, 
      "Check_Out",
      LookUp(
         CheckIns, 
         RequestID=ID
      ).Checkout
   ),	  
   Check_Out=Blank()
)

Hey, not working. 

I need to do the addcolumns command? It's not possible directly through a lookup?

@Miguel_MESP ,

If you want to filter by the field - yes you need to add the column. What is not working?
