How to convert Tableau calculation to Power BI?

[Ashley1]

Hello, 

I am very new to Power BI. My company is looking into option of transitioning to Power BI from Tableau.

My question is how do I convert Tableau Calculation to Power BI?

For eg:

DATE({FIXED [Order Number]: MIN(IF [Customer ID]='0510'
THEN [Order Date Time]
END )})

Thank you @vicky_ for the solution and for the links. They seem to be very good source. Really appreciate it 🙂

Try something like:
Measure = CALCULATE(MIN(Table[Order Date Time]), Table[Customer ID]="0510", ALLEXCEPT(Table[Order Number]))

If you've already got the table grouped by Order Number, then you should be able to skip the last CALCULATE argument. 

Here's the docs for the above functions:

and I also recommend giving this a read - https://www.sqlbi.com/articles/introducing-calculate-in-dax/ as it helped me a lot when I transitioned from Tableau to PowerBI.
