The correct answer is that the ALL('Date') function removes the filter context, causing the running total to break and instead return the total sales for all dates. This happens because ALL('Date') acts as a filter modifier inside CALCULATE, stripping away any existing date filters from the visual or slicer, so the measure no longer accumulates row by row but computes a static grand total. On the Microsoft Power BI Data Analyst PL-300 exam, this scenario tests your understanding of how filter context and context transition interact with DAX time intelligence—a common trap is confusing ALL with ALLSELECTED, which preserves external filters. Remember, ALL is the "reset button" for filters: it clears the current context entirely, which is why your running total stops accumulating and shows the overall total instead. A useful memory tip: "ALL removes, ALLSELECTED keeps the outer sweep."
PL-300 Visualize and analyze the data Practice Question
This PL-300 practice question tests your understanding of visualize and analyze the data. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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 the selected date only. What is the problem?
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
```
A
The measure should use ALLEXCEPT instead of ALL.
Why wrong: ALLEXCEPT would keep other filters but still remove date filter; need to keep date filter.
B
The ALL('Date') function removes the filter context, so the calculation returns total sales for all dates.
ALL removes the filter on Date, so the condition 'Date'[Date] <= SelectedDate applies to all dates, but without a filter, it sums all sales.
C
The VAR SelectedDate should be MIN instead of MAX.
Why wrong: MIN vs MAX does not change the issue; both return a single date.
D
The relationship between Sales and Date is inactive.
Why wrong: Inactive relationship would cause no filtering, but measure uses Date column.
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.
Option B is correct because ALL('Date') removes all date filters, causing the CALCULATE to ignore the date filter context. Option A is wrong because VAR does not affect the result. Option C is wrong because relationship direction does not cause this specific issue. Option D is wrong because ALL does not cause circular dependency.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
