Exam PL-300 topic 2 question 76 discussion

Actual exam question from Microsoft's PL-300
Question #: 76
Topic #: 2
[All PL-300 Questions]

HOTSPOT
-

You are creating a Power BI model to analyze inventory.

You load data into three tables named Date, Product, and Inventory. The Inventory table relates to the Date and Product tables by using one-to-many relationships.

Inventory data is recorded daily with no exceptions. The correct inventory quantity for a given product in a month is the last recorded value for that month.

You need to write a DAX measure that will show the correct inventory value when a user analyzes inventory by year, month, or date.

How should you complete the measure? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Calculate LastNonBlankValue LASTDATE will NOT work. Date - is a date table and it contains all days of the calendar month continuously so it will always return the last day of the month even if there is no inventory records. "The correct inventory quantity for a given product in a month is the last recorded value for that month.". That's why we should use LastNonBlankValue instead.

LASTNONBLANKVALUE also requires an expression though. https://learn.microsoft.com/nl-nl/dax/lastnonblankvalue-function-dax

The right answer should be LastDate. It can't be LASTNONBLANK as it is requires an expresion. Please find below the sintax for LASTNONBLANK: - LASTNONBLANK(<column>,<expression>) This function is typically used to return the last value of a column for which the expression is not blank. For example, you could get the last value for which there were sales of a product (for instance if you want to exclude holidays from the calculation).

It also says 'Inventory data is recorded daily with no exceptions.' so I concluded that each day would have an inventory record.

how do you guys use Date[Date] as the expression in the LASTNONBLANK function like in the example from earlier answers "LASTNONBLANK('Inventory'[QuantityAvailable], 'Date'[Date])"?

I was able to do it this way: CALCULATE(SUM(Inventory[QuantityAvailable]),LASTDATE('Inventory'[Date]) ) my sample dataset dates (Jan-Apr 2023) and Date table (Jan-Dec 2023) dates probably not tuned properly so if I use Date[Date] instead of Inventory[Date] my measure returns Blank

Calculate LastDate Last Inventory Count = CALCULATE( LASTNONBLANK('Inventory'[QuantityAvailable], 'Date'[Date]), LASTDATE('Date'[Date]) )

CALCULATE LASTDATE It isn't MAX because that would returns an scalar instead of a table. https://www.sqlbi.com/blog/marco/2013/10/22/difference-between-lastdate-and-max-for-semi-additive-measures-in-dax/

I think this questions is not well explained. Let me say why ( from brazil, sorry if I write wrong): 1. That is form to create a calendar table based in the dates of the fact table, for example: if I create based on the fact table, the last date will be the last date of the fact table. 2. Other way of create a calendar table is just to put the days of a number of years that you want, so, in this case the last date will be the last date of the calendar table and not the last date of the fact table. So, in my opinion it is better annul this question, or consider lastnonblankvalue and lastdate correct.
