How to catch the latest BOM item based on the latest effective in date

Hey there,

 

I try to create a table to highlight the latest BOM table. (see below master data) . In our master data table, it has all records of BOM with the effective in and effective out time). But i want to create a table to visualize the BOM at the production site level based on the latest effective in date (A and B are different type of components) 

 

Master Data Table

 

 

Below is the BOM list based on the latest effective in date. 

 

So my question is 

 

1: Not sure I should create a measure or column to have those info

 

2: How I should write the dax

 

Thanks a lot!
