Create a 3rd Collection (i.e., JOIN) From Two Collections

[bolin-stratus]

I am creating two collections from their respective SharePoint lists.  Both SP lists have a lot of columns but I only require 2 columns from each list.  This is working as expected. 

ClearCollect(colDashboardOne, ShowColumns('Deal-Intake-App', "Title", "Close_x002d_Date" ));
ClearCollect(colDashboardTwo, ShowColumns('Deal-Updates', "Deal_x002d_Ref_x002d_ID", "Pursuit_x002d_Closedown_x002d_Da" ));

However, when I create a third collection from the these two, I am missing a column.  What is the easiest method to create a 3rd collection that includes all four columns? The JOIN is where the Title = Deal_x002d_Ref_x002d_ID.  Any recommendations are greatly appreciated.

Hi @bolin-stratus ,

ClearCollect(thirdCollection, AddColumns(colDashboardOne,"Pursuit_x002d_Closedown_x002d_Da",LookUp(colDashboardTwo, Title = Deal_x002d_Ref_x002d_ID, "Pursuit_x002d_Closedown_x002d_Da"))

Actually I think that you'll have 3 columns, right ?

Hope it helps !

@gabibalaban - Thanks for the quick response.   The code you provided almost solves the issue but the Pursuit Closedown Date is blank for some reason.  From the image below you can see there is data in the Pursuit Closedown Date in the colDashboardTwo collection.  However, although the thirdCollection has a Pursuit Closedown Date column, there is no data.

Oups ... I mistype my formula, there is no need of double-quotes: 

ClearCollect(thirdCollection, AddColumns(colDashboardOne,"Pursuit_x002d_Closedown_x002d_Da",LookUp(colDashboardTwo, Title = Deal_x002d_Ref_x002d_ID, Pursuit_x002d_Closedown_x002d_Da))
