Measure to filter rows Using another measure DAX

In summary, this measure identifies sales quantities that deviate significantly from the user's average sales within a year for a specific product brand, helping to flag unusual sales patterns.

User Year Decalartion Anomaly =
var UserYearProductMean =
CALCULATE(
    AVERAGE(ft_qualityesod[quantity]),
    ALLEXCEPT(pbidimusers, pbidimusers[username]),
    ALLEXCEPT(DateTable, DateTable[Year]),
    ALLEXCEPT(DimProduct, DimProduct[category], DimProduct[product_line]),
    ft_qualityesod[brand] = "ttm"
)

// User-Year-Product Standard Deviation
var UserYearProductStdDev =
CALCULATE(
    STDEV.P(ft_qualityesod[Quantity]),
    ALLEXCEPT(pbidimusers, pbidimusers[username]),
    ALLEXCEPT(DateTable, DateTable[Year]),
    ALLEXCEPT(DimProduct, DimProduct[category], DimProduct[product_line]),
    ft_qualityesod[brand] = "ttm"
)

// User-Year-Product Anomaly Detection
VAR Quantity = SUM(ft_qualityesod[quantity])
VAR Mean = UserYearProductMean
VAR StandarDeviation = UserYearProductStdDev
VAR Threshold = 1.96 * StandarDeviation
VAR UpperBound = Mean + Threshold
VAR LowerBound = Mean - Threshold
var result =
IF(
     Quantity > UpperBound || Quantity < LowerBound,
    1,
    0
)
RETURN result
---------------------------------------------
This is the result of my measure : 
we have a user name, product_line, category on row, year and month on columns and  the measure  User Year Decalartion Anomaly as value
Capture.JPG

Based on that measure, I want to create a new measure that uses this result to achieve the following:

The expected output is:
Create a new measure that allows me to get the rows where there is at least one '1' in the first measure.


User name Product line  Category            MeasureValue 
A                  PL                 new                    0 ( I don't have any 1 in the value)
A                  PL                 retread                1 (I have 1 in the month 10 on a year 2023) 
A                  TC                  all                       1 (I have 1 in the month 10 on a year 2023)

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

DAX is easy, CALCULATE makes DAX hard...

I corrected the post. I can't post the sample, but I tried to be as clear as possible in my explanation.
