[All PL-300 Questions]

HOTSPOT -

You have a Power BI semantic model that contains a table named Item. The Item table contains a column named Quantity.

You need to create a DAX query that meets the following requirements:

• The rank of items must be calculated according to the values in Quantity.
• Ranking must NOT be skipped if two or more items have the same value in Quantity.
• If an item is unfiltered, the total of Quantity must display a blank value.

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

NOTE: Each correct selection is worth one point.

HASONEVALUE ('Item'[Item]) check if 'item' is filtered to a single value. if not, it returns blank by default. Rank method : DENSE ensure that ranks are not skipped when there are ties.

SELECTEDVALUE returns the actual value of the column if there is exactly one unique value, or it returns an alternate result (or BLANK) if there isn’t—its focus is on extracting a value, not simply checking whether there is exactly one. HASONEVALUE is designed purely as a Boolean check. It returns TRUE if there is exactly one distinct value and FALSE otherwise, which is precisely what you need for controlling the logic (calculate rank for a single item, BLANK for totals).

RANKX(<table>, <expression>[, <value>[, <order>[, <ties>]]]) <expression> to evaluate for ranking (within the <table>) <value> is optional; if omitted, current row's value in <expression> is used <order> (optional) to set sort order (ASC, DESC) <ties> is also optional and determines how ties are handled SKIP: skips rank for ties (e.g ranks 1,2,2,4) DENSE does not skip ranks for ties (e.g. ranks 1,2,2,3)

HASONEVALUE garantiza que la fórmula se ejecute únicamente cuando haya un solo valor de Item seleccionado. Esto evita que se devuelva un valor de clasificación cuando no se ha seleccionado ningún elemento, cumpliendo con el requisito de mostrar un valor en blanco si no se ha filtrado ningún elemento. DENSE se asegura de que, si dos o más elementos tienen la misma cantidad, no se omitan números en la clasificación, lo cual era otro de los requisitos.
