Conditional Sum in Power BI Matrix - powerbi

Question

I have a Power BI matrix with 3 columns: 2019, 2020, and 2021. Each row is an item number, and each value is a total quantity produced in the corresponding year column.
I am trying to find a way to display the sum of ONLY items that were blank in 2019 and 2020, BUT have a total quantity in the 2021 column. Is there a way to conditionally format this?
Basically, another way of saying the logic is: total sum of all items where 2019 AND 2020 are blank, AND 2021 is not blank.

Answer 1

Try this solution if it helps then mark it as the answer.
Create a calculated column with the following DAX:
Column =
IF (
(
Table[Year] = 2019 || Table[Year] = 2020 ),
IF ( ISBLANK ( Table[Item] ), ( Table[Quant] ) ),
IF ( Table[Year] = 2021, IF ( ISNUMBER ( Table[Item] ), ( Table[Quant] ) ) )
)
Input I used:-
Output where 2019 and 2020 Items are blank and 2021 where Items are not blank:-

Answer 2

You can create the following measure:
Measure =
IF (
CALCULATE(
SUM(Table[Quantity]),
Table[Year] => 2019,
Table[Year] <= 2020,
) > 0,
0,
CALCULATE(
SUM(Table[Quantity]),
Table[Year] = 2021
)
)
And in the table you should filter that visual so it only shows values where this Measure is > 0. However, if your intention is to have this dynamically (i.e. so this still makes sense next year with years 2020, 2021 and 2022), I would recommend this:
Measure =
IF (
CALCULATE(
SUM(Table[Quantity]),
Table[Year] => YEAR(TODAY()) - 2,
Table[Year] <= YEAR(TODAY()) - 1,
) > 0,
0,
CALCULATE(
SUM(Table[Quantity]),
Table[Year] = YEAR(TODAY())
)
)
