PL-300 Visualize and analyze the data Practice Question
Exhibit
Refer to the exhibit.
```dax
Total Sales =
VAR SelectedDate = MAX('Date'[Date])
VAR SalesToDate =
CALCULATE(
SUM('Sales'[Amount]),
'Date'[Date] <= SelectedDate,
ALL('Date')
)
RETURN
SalesToDate
```You have a measure as shown in the exhibit. The sales amount is not accumulating correctly; instead, it shows the total sales for all dates, regardless of the selected date filter. What is the problem?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The ALL('Date') function removes the filter context, so the calculation returns total sales for all dates.
Using ALL('Date') within CALCULATE removes the filter context on the Date table, causing the measure to return the total sales across all dates, not the current date context. Option A is incorrect; ALLEXCEPT would keep certain filters, but the problem here is specifically the removal of all date filters by ALL. Option C is incorrect; using MIN versus MAX in VAR SelectedDate does not cause the described behavior; the issue is the ALL function. Option D is incorrect; an inactive relationship would prevent proper filtering but would not result in the measure returning the total for all dates; the symptom would be different.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The measure should use ALLEXCEPT instead of ALL.
Why it's wrong here
ALLEXCEPT removes filters except on listed columns, so it would still clear the Date filter and return total sales. It is tempting because ALLEXCEPT is correct when you must preserve filters on specific columns such as Product while clearing others, which is not this requirement.
- ✓
The ALL('Date') function removes the filter context, so the calculation returns total sales for all dates.
Why this is correct
ALL('Date') strips the date filter context from the Date table, so the measure aggregates every row regardless of slicer or axis selection. Removing that filter is precisely what makes the result show total sales for all dates instead of accumulating.
- ✗
The VAR SelectedDate should be MIN instead of MAX.
Why it's wrong here
MIN vs MAX does not change the issue; both return a single date.
- ✗
The relationship between Sales and Date is inactive.
Why it's wrong here
An inactive relationship is not automatically applied in filter context, so it would not by itself return total sales across all dates. It is tempting because activating a relationship with USERELATIONSHIP is correct when a role-playing dimension requires an alternative join path.
