The error message you're encountering indicates that there's an issue with how you're using the True/False expression within your DAX calculation. In DAX, when you're using expressions like [TL Refusal (QLI)]=0 or 'Facts'[Status]="Return", they need to evaluate to a True or False value, but they should be related to specific columns.
In your calculation, it seems like you're trying to calculate the percentage of customers where TL Refusal (QLI) is equal to 0, and the status is "Return". However, the structure of your calculation might be causing the issue.
Here's how you can revise your DAX expression:
% TL Refusal =
DIVIDE(
CALCULATE(
DISTINCTCOUNT('Facts'[Customer]),
'Facts'[TL Refusal (QLI)] = 0,
'Facts'[Status] = "Return"
),
CALCULATE(
DISTINCTCOUNT('Facts'[Customer]),
'Facts'[Status] = "Return"
)
)
In this revision, I've modified the CALCULATE function to include the conditions 'Facts'[TL Refusal (QLI)] = 0 and 'Facts'[Status] = "Return" within it. This ensures that each condition is associated with the appropriate column from the 'Facts' table.
Please replace 'Facts'[TL Refusal (QLI)] and 'Facts'[Status] with the correct column names if they are different. Make sure the column names and table names are correct, as DAX is case-sensitive. This revision should resolve the error you're encountering.
