Create measure to calculate value of attributes

[Hugo62Glu]

Hello everyone, 

I want to create a P&L waterfall, from gross sales to gross margin. For this, I have a table which comprises ,a column for gross sales, a column for net sales, margin, a column for the year, column for product type and so on.  To create the visualisation I need, I am using an intermediate table, with the first column called "attributes" including gross sales, trade terms, promotions, net sales,COGS margin etc. Then, I will need to create 3 measures: value for the base (only value for gross sales, net sales and margin), a measure for calculating negative value (so only calculating the sum of trade terms, promotions and COGS), a measure which will be showed as transparent (little trick to set up a waterfall with a bar chart). 

I was wondering how to create those 3 caculations based on the columns in my first table. For my first measure and if I were to use excel, it will be: if(attribute="gross sales", sum(gross sales), if(attribute="net sales", sum(net sales), if(attribute="gross margin", sum(gross margin),0). I want these measures to be linked to my first table in order to use slicers and the value will update. 

However, I don't know how to create these 3 measures based on my attributes displayed as rows. 

Would you have an idea on how I can do it? 

Thanks in advance for your help

Hi @Hugo62Glu ,

You can use Switch() function to achiveve this goal.

Here is a simple example:

I created three simple measures, each of them is just the name of themselves.

Then create a new measure :

Measure = 
SWITCH(SELECTEDVALUE('intermediate table'[attributes]),
"gross margin",[gross margin],
"gross sales",[gross sales],
"net sales",[net sales],0)

Final output:
