You have a Power BI report that imports a date table and a sales table from an Azure SQL database data source. The sales table has the following date foreign keys:
✑ Due Date
✑ Order Date
✑ Delivery Date
You need to support the analysis of sales over time based on all the date foreign keys.
Solution: You create measures that use the USERELATIONSHIP DAX function to filter sales on the active relationship between the sales table and the date table.
Does this meet the goal?
Answer:
B
Instead: Solution: From the Fields pane, you rename the date table as Due Date. You use a DAX expression to create Order Date and Delivery Date as calculated tables.

Answer:
Box 1: CALCULATE -
CALCULATE evaluates an expression in a modified filter context.
Syntax: CALCULATE(<expression>[, <filter1> [, <filter2> [, ג€¦]]])
The expression used as the first parameter is essentially the same as a measure.
Filters can be:
Boolean filter expressions -
Table filter expressions -
Filter modification functions -
Table filter expression -
A table expression filter applies a table object as a filter. It could be a reference to a model table, but more likely it's a function that returns a table object. You can use the FILTER function to apply complex filter conditions, including those that cannot be defined by a Boolean filter expression.
Box 2: AND -
Box 3: FILTER -
FILTER returns a table that represents a subset of another table or expression.
Syntax: FILTER(<table>,<filter>)
Note: DISTINCT returns a one-column table that contains the distinct values from the specified column. In other words, duplicate values are removed and only unique values are returned.
