Take previous cell value to build a column

[nicolasvc]

I have in table "Products" a simple column with one cell:

Products

1250

And other table "dates"

demand	offer	stock
1321	1200	1250+1321-1200
2132	2023	1371+2132-2023

And I need to fill the column stock with the value 1250 from table Products and then add 1321 - 1200 for the first cell, then with this value 1250+1321-1200= 1371 I need to do the same procedure, but for the next rows down, how can I take the value of the previous cell in the same column and work from it?

Hi @nicolasvc ,

Add an index column. Transform data>> Add column>>From 1

Create a column.

stock = calculate(sum('dates table'[demand])-sum('dates table'[offer])+MAX(products[Products]),FILTER('dates table',[index]<=EARLIER('dates table'[Index])))

Hi @nicolasvc ,

Does the "dates" table provide a product_id and a date to sort by?

How are the products and dates tables related?
