Calculate Profitability with sales and costs table with different dates

[Syndicate_Admin]

Hello! I'm a few days ago with this matter, and I do not know how to solve it!

I have a sales table with the amounts sold per month, and another of purchases with the purchases made each month. To know the profitability of the month, yes I have the sales and quantities sold belonging to each month, but not for all the products I have purchases that same month, so that it does not cost me $ 0 for that period, I need to take the cost of the last purchase, not of the whole table but before the month I am consulting.

If anyone can help me, thank you very much! 🙏

@Syndicate_Admin , Please create a new column in the sales using purchase, please change column name as as per need

New column in sales  =

var _max = maxx(filter(purchase, Purchase[Item] = sales[item]  && Purchase[date] <=sales[date]) ,Purchase[date] )

return

maxx(filter(purchase, Purchase[Item] = sales[item]  && Purchase[date] = _max ) ,Purchase[Price] )
