💡 Hint

Common Mistakes

Using USERELATIONSHIP when the active relationship is already in use.

Using ALL removes filters and breaks the calculation.

The active relationship is used by default in CALCULATE, so no need to specify USERELATIONSHIP. Using FILTER keeps the active relationship context.

💡 Hint

Common Mistakes

Using FILTER instead of USERELATIONSHIP.

Using ALL removes filters and breaks the calculation.

USERELATIONSHIP activates an inactive relationship inside CALCULATE.

💡 Hint

Common Mistakes

Trying to filter tables without activating the relationship.

Using RELATED incorrectly in this context.

To use an inactive relationship in CALCULATE, you must specify USERELATIONSHIP.

hard

Fill both blanks to calculate sales using the inactive relationship and filter only orders after 2020.

Power BI

Total Sales After 2020 = CALCULATE(SUM(Sales[Amount]), [1], [2])

Drag options to blanks, or click blank then click option'

AUSERELATIONSHIP(Date[Date], Sales[ShipDate])

BFILTER(Sales, Sales[OrderDate] > DATE(2020,1,1))

CFILTER(Sales, Sales[ShipDate] > DATE(2020,1,1))

DALL(Date)

💡 Hint

Common Mistakes

Filtering by OrderDate instead of ShipDate.

Not activating the inactive relationship.

USERELATIONSHIP activates the inactive relationship on ShipDate, and FILTER limits sales to ShipDate after 2020.

5fill in blank

hard

Fill all three blanks to create a measure that sums sales amount using the inactive relationship, filters by ShipDate after 2020, and ignores other filters on Date.

Power BI

Total Sales Custom = CALCULATE(SUM(Sales[Amount]), [1], [2], [3])

Drag options to blanks, or click blank then click option'

AUSERELATIONSHIP(Date[Date], Sales[ShipDate])

BFILTER(Sales, Sales[ShipDate] > DATE(2020,1,1))

CALL(Date)

DFILTER(Sales, Sales[OrderDate] > DATE(2020,1,1))

Attempts:

3 left

💡 Hint

Common Mistakes

Filtering by OrderDate instead of ShipDate.

Not removing other filters on Date with ALL.

Not activating the inactive relationship.

USERELATIONSHIP activates the inactive relationship, FILTER limits sales by ShipDate after 2020, and ALL(Date) removes other filters on Date to avoid conflicts.

Practice

1. What is the main difference between an active and an inactive relationship in Power BI?

easy

A. Active relationships are used automatically in calculations, inactive require USERELATIONSHIP()

B. Inactive relationships are used automatically, active require USERELATIONSHIP()

C. Both active and inactive relationships work automatically without extra functions

D. Inactive relationships cannot be used in any calculations

Solution

1. Step 1: Understand active relationships

   Active relationships are automatically applied in calculations and visuals without extra effort.

2. Step 2: Understand inactive relationships

   Inactive relationships do not apply automatically; you must use USERELATIONSHIP() in DAX to activate them temporarily.

3. Final Answer:

   Active relationships are used automatically in calculations, inactive require USERELATIONSHIP() -> Option A

4. Quick Check:

   Active = automatic, inactive = USERELATIONSHIP() [OK]

Hint: Active works by default; inactive needs USERELATIONSHIP() [OK]

Common Mistakes:

• Thinking inactive relationships work automatically
• Confusing USERELATIONSHIP() usage
• Believing inactive relationships cannot be used

2. Which of the following is the correct syntax to activate an inactive relationship in a measure?

easy

A. CALCULATE(SUM(Sales[Amount]), USERELATIONSHIP(Sales[Date], Calendar[Date]))

B. CALCULATE(SUM(Sales[Amount]), ACTIVERELATIONSHIP(Sales[Date], Calendar[Date]))

C. SUM(Sales[Amount]) + USERELATIONSHIP(Sales[Date], Calendar[Date])

D. CALCULATE(SUM(Sales[Amount]), RELATIONSHIP(Sales[Date], Calendar[Date]))

Solution

1. Step 1: Recall USERELATIONSHIP() usage

   USERELATIONSHIP() is used inside CALCULATE() to activate an inactive relationship temporarily.

2. Step 2: Check syntax correctness

   CALCULATE(SUM(Sales[Amount]), USERELATIONSHIP(Sales[Date], Calendar[Date])) uses CALCULATE with USERELATIONSHIP and correct column references, matching the correct syntax.

3. Final Answer:

   CALCULATE(SUM(Sales[Amount]), USERELATIONSHIP(Sales[Date], Calendar[Date])) -> Option A

4. Quick Check:

   USERELATIONSHIP inside CALCULATE is correct syntax [OK]

Hint: USERELATIONSHIP() must be inside CALCULATE() [OK]

Common Mistakes:

• Using ACTIVERELATIONSHIP() which does not exist
• Adding USERELATIONSHIP() outside CALCULATE()
• Using RELATIONSHIP() instead of USERELATIONSHIP()

3. Given the following measure:

Sales Amount by Order Date = CALCULATE(SUM(Sales[Amount]), USERELATIONSHIP(Sales[OrderDate], Calendar[Date]))

What will this measure calculate if the active relationship is between Sales[ShipDate] and Calendar[Date]?

medium

A. Sum of Sales Amount filtered by ShipDate

B. Sum of Sales Amount ignoring any date filter

C. Sum of Sales Amount filtered by OrderDate using inactive relationship

D. Error because USERELATIONSHIP cannot be used with OrderDate

Solution

1. Step 1: Identify active and inactive relationships

   The active relationship is Sales[ShipDate] to Calendar[Date]. The relationship Sales[OrderDate] to Calendar[Date] is inactive.

2. Step 2: Understand USERELATIONSHIP effect

   Using USERELATIONSHIP activates the inactive relationship on OrderDate temporarily for this measure.

3. Final Answer:

   Sum of Sales Amount filtered by OrderDate using inactive relationship -> Option C

4. Quick Check:

   USERELATIONSHIP activates inactive relationship [OK]

Hint: USERELATIONSHIP switches to inactive relationship filter [OK]

Common Mistakes:

• Assuming measure uses active ShipDate filter
• Thinking USERELATIONSHIP causes error
• Ignoring inactive relationship usage

4. You wrote this measure:

Total Sales = CALCULATE(SUM(Sales[Amount]), USERELATIONSHIP(Sales[Date], Calendar[Date]))

But it returns the same result as SUM(Sales[Amount]). What is the most likely problem?

medium

A. CALCULATE cannot be used with USERELATIONSHIP

B. The relationship between Sales[Date] and Calendar[Date] is already active

C. The Sales[Date] column does not exist in the table

D. USERELATIONSHIP() is misspelled and causes a syntax error

Solution

1. Step 1: Check relationship status

   If the relationship between Sales[Date] and Calendar[Date] is active, USERELATIONSHIP() has no effect because the active relationship is already used.

2. Step 2: Understand measure behavior

   The measure behaves like SUM(Sales[Amount]) filtered by the active relationship, so results match.

3. Final Answer:

   The relationship between Sales[Date] and Calendar[Date] is already active -> Option B

4. Quick Check:

   USERELATIONSHIP only affects inactive relationships [OK]

Hint: USERELATIONSHIP only changes inactive relationships [OK]

Common Mistakes:

• Assuming USERELATIONSHIP causes syntax error
• Thinking CALCULATE cannot use USERELATIONSHIP
• Ignoring relationship status

5. You have two date columns in Sales: OrderDate and ShipDate. The active relationship is between ShipDate and Calendar[Date]. You want a report showing total sales by OrderDate without changing the active relationship. Which approach is best?

hard

A. Create a new Calendar table for OrderDate and link it actively

B. Change the active relationship to OrderDate and remove ShipDate relationship

C. Use the active relationship and ignore OrderDate column

D. Create a measure using CALCULATE with USERELATIONSHIP(Sales[OrderDate], Calendar[Date])

Solution

1. Step 1: Understand relationship setup

   ShipDate is active; OrderDate relationship is inactive to Calendar[Date]. Changing active relationship affects all reports.

2. Step 2: Use USERELATIONSHIP in measure

   Using CALCULATE with USERELATIONSHIP activates the inactive OrderDate relationship temporarily without changing model.

3. Step 3: Evaluate other options

   Changing active relationship or creating new Calendar table is more complex and less flexible.

4. Final Answer:

   Create a measure using CALCULATE with USERELATIONSHIP(Sales[OrderDate], Calendar[Date]) -> Option D

5. Quick Check:

   USERELATIONSHIP enables alternate date filtering [OK]

Hint: Use USERELATIONSHIP to activate alternate date without model changes [OK]

Common Mistakes:

• Switching active relationship instead of using USERELATIONSHIP
• Ignoring inactive relationship usage
• Creating unnecessary new tables
