% calculation per row

[TomerIwanir1]

Hello

I'm trying to create a calculate column of cost % out of total cost with filters, attaching the pic below for example 

I have two column that filtering my calc, the right column (cost %) is what im trying to create, please note that I have a lot of month and products so creating a measure oer each one is not relevent.

thx again !

I'm getting all 100 %

Product_Share = 'Sales'[Total Cost (Calc)] / CALCULATE(SUM('Sales'[Total Cost (Calc)]),'Sales'[Month] = EARLIER('Sales'[Month]),'Sales'[Product_Group (Calc)] = EARLIER('Sales'[Product_Group (Calc)]))

where cost is a decimal number,month is a date and product is text

@TomerIwanir1 

Are you sure that you have written a column , and not measure??

I think so, pls see below :

I think you forgot to write "Filter". so write it as follows:

Product_Share = 'Sales'[Total Cost (Calc)] / CALCULATE(SUM('Sales'[Total Cost (Calc)]),Filter ('Sales','Sales'[Month] = EARLIER('Sales'[Month]) && 'Sales'[Product_Group (Calc)] = EARLIER('Sales'[Product_Group (Calc)]))

* I highlight updated part*

Yes ! I changed the "," into "&&" at the filter:

product_Share = 'Sales'[Total Cost (Calc)] / CALCULATE(SUM('Sales'[Total Cost (Calc)]),FILTER(Sales,Sales[Month] = EARLIER(Sales[Month])&& Sales[Product_Group (Calc)] = EARLIER(Sales[Product_Group (Calc)])))

thank you !

Hi @TomerIwanir1 

You can write a column as follows and change the format as percentage:

Product_Share := Cost / calculate(sum(cost) , filter (your_table , period= earlier (period) && product= earlier (product))
