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 three dates at the same time. Solution: You create measures that use the USERELATIONSHIP DAX function to filter sales on the inactive relationships between sales table and the date table. Does this meet the goal?

DRAG DROP You have a Microsoft Power BI data model that contains three tables named Sales, Product, and Date. The Sales table has an existing measure named [Total Sales] that sums the total sales from the Sales table. You need to write a calculation that returns the percentage of total sales that a selected ProductCategoryName value represents. The calculation must respect any slicers on ProductCategoryName and must show the percentage of visible total sales. For example, if there are four ProductCategoryName values, and a user filters one out, a table showing ProductCategoryName and the calculation must sum up to 100 percent. How should you complete the calculation? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.

Question 350 - PL-300 discussion

You have a Power BI data model 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 three dates at the same time.

Solution: From the Data pane, you rename the date table as Due Date. You use a DAX expression to create Order Date and Deliver Date as calculated tables. You create active relationships between the sales table and each date table.

Does this meet the goal?

No

Answers
B.

No

Suggested answer: B

Explanation:

Renaming the date table and creating calculated tables for 'Order Date' and 'Delivery Date' with DAX expressions would not fully meet the goal. Power BI only allows one active relationship between two tables at a time. Therefore, you cannot have active relationships between the sales table and all three date tables simultaneously.

Instead, you would typically create one active relationship (e.g., with 'Order Date') and use DAX functions like USERELATIONSHIP to switch between different relationships when needed for analysis. Alternatively, you could use a single date table and create multiple relationships, using inactive relationships and the USERELATIONSHIP function to activate them in specific measures.
