Help Needed with Power BI Measure to Count Unique Key Controls
I am working on a Power BI report where I need to count the number of unique key controls. I have two tables: ControlRelations and DimControl.
The ControlRelations table contains multiple instances of controls (since it also lists out relations with other dimensions), there is a column called IsKeyControl and it's either True or False. I would like to create a measure that is similar to this:
TotalKeyControls =
CALCULATE(
COUNTROWS('Historical Controls'),
'Historical Controls'[IsKeyControl] = TRUE()
)
However, since there are multiple instances of the same control (denoted by the same Guid), it counts 1 key control as 1,2,3,4.....etc. Each control will have the same value for IsKeyControl. So for any Guid = Guid, IsKeyControl = IsKeyControl.
What I am looking for is a measure that will count the number of keycontrols and only count 1 key control per unique Guid.
Can someone help me out please? Copilot has been of no use to me.
Kind regards
