[operez901028]

Hi, can you help with one issue in PowerBi i create a report and i this report i see the scrap, and total cost of production, i use the next dax for calculate the cost of production

= SUMX(lizventas,lizventas[Quantity Invoiced] * RELATED(COSTO[Cost] ))

but when Bi make the operation the result is worng for example.

in all rows the result is worng, for example

first row 

360 * 36.27 = 13,056.83

and the correct result is

13,057.2

 and this is with all multiply in this dax.

Thank you

Hi,

The "error" seems a rounding problem.

I suggest you use the same precision in your all numbers to see the exact value.

Hi @operez901028 

its better to create topics like this in another part of community: https://community.powerbi.com/t5/Desktop/bd-p/power-bi-designer

So, anyway. everything is saying that you have a round-problem

13056.83/360 = 36.269

so, try to click left mouse on your field Cost then go to Modelling pane or Column tools pane (in the new version of pbi desktop) and set number of decimal as 3
