How do I create calculated column in power bi? - powerbi

Question

I am new to Power BI and was wondering if someone can help me.
I have a table
A B Status
---------------------------
Asset1 B1 Compliant
Asset1 B2 N/A
Asset2 B1 Non- Compliant
Asset2 B2 Compliant
Asset3 B1 Compliant
Asset3 B2 Compliant
I have to find the Asset which are 100% compliant(Count of Asset where status of all the rows of Column B is Compliant and not non Compliant and we need to ignore N/A.
Out put I want
A 100%Compliant
Asset1 Y
Asset2 N
Asset3 Y
Thanks

Answer 1

You can create an extra column in your table:
100% Cpmpliant =
var asset = Compliant[A]
var allRows = CALCULATE(COUNTROWS(Compliant); FILTER(Compliant; Compliant[A] = asset && Compliant[Status] <> "N/A"))
var compliantRows = CALCULATE(COUNTROWS(Compliant); FILTER(Compliant; Compliant[A] = asset && Compliant[Status] = "Compliant"))
return if (allRows = compliantRows; "Y";"N")
This calculates the rows of the asset without the N/A and compares it against teh rowcount of the compliant. If this is equal, they are all compliant-
Next you can create a visual with two columns ass below:

Edited:
You can create a measure:
IsCompliant =
VAR NumNonCompliant = CALCULATE(COUNTAX('Table', [B]), 'Table'[Status] = "Non - Compliant")
RETURN IF(NumNonCompliant = 0, "Y", "N")
The variable NumConCompliant calculates the number of rows with status = "Non - Compliant". Then it is compared with 0 to find any non-compliance.
Then the measure returns the state of "A" in the given context. This gives you the flexibility of assigning compliance measure to a combination of assets. For example if you filter data on "A = Asset1", the result would be "Y", and (A = Asset1 || A = Asset2) results in a "N". (Since the combination of Asset1 & Asset2 are non-compliant).
Refer to this doc about measures and contexts.
