Hello Rahul, I have used the same logic on a smaller dataset and then built my historical dataset. I used three unique identifiers to make the join. Thank you very much!

Thank you very much, Rahul. I tried doing these steps and looks like the left join is taking more than 14hours of time. It definitely ran well when I individually ran the queries. I might have to tweak the dataflow a little. Let me do that first and then, will accept this as a solution once it runs. Best!
