Hello,
I am trying to create a table in which I want to include the rent, the square feet and calculate the Rent/square foot. In the subtotal I get wrong number because the default action in Power BI table is to sum the values in Rent/Square column. In my case I want to divide the total of rent by the total of square foot and not to sum the Rent Square feet comumn. Can you please support with this?
Please see an example below.
Many thanks,
Marios

Hi
I guess you computed your Rent/Square Feet as a calculated column using the DAX language.
Because this is a ratio, you'd better use a measure rather than a calculated column. See more explanation here: https://exceleratorbi.com.au/calculated-columns-vs-measures-dax/
Ralph Kimball summarizes this concept with this sentence : "You should always to the ratios of the sum rather than the sum of the ratios"
So, in your example, go to 'Modelling' Tab, create the following measure:
Rent/Squarefeet = Divide ( Sum(YourTable[Rent]) , Sum(YourTable[Square Feet]) , 0)
And use this brand new measure in the "values" of your tables & matrix.

Many thanks Excelside, this looks to work fine.
