How to get new column with value from previous date (with additional conditions)

[gwaczoka]

Hi,

I have a table, here is the example:

I'd like to add a new column which I don't know how to get (last one called "Prev day flag"

Explanation:

I have a table with lists of products (Item ID) and suppliers for each product.

Everyday I have a different flag for this product and I want to know what was the flag previous day. Not always days are +1, sometime it is +7, so then I want to know what was the flag  7 days ago

I tried to use CALCULATE + EARLIER function, but it doesn't work. As far as I know, we use calculate with metrics, but here I need a column...

Please help!:)

Thank you for your response. It doesn't work when I apply that in my original table, I think that I'd need another condition with the supplier and itemid, because I have a lot of ITEM IDs and suppliers for one Item ID, and it should be in there I guess...
