Find the nearest value within a month

[heejinyune]

Hello community! 

Is anyone familiar with writing the Dax Programming to find the nearest (closest ) value in the table?

For example, My table is like this:

And I want to find the nearest Model built time value with 1 month average built time (in this case, today date is 2022/11/16 so 

(213 + 444 + 532 + 111 / 4 ) = 325 ) 

so the nearest value of 325 in this table should be 213 (A125) not 345 (A124) as that model not in a past month from current date.

Therefore, how do i return 213 using the dax programming?

Thank you so much for your help!

Hi, @heejinyune 

You can try the following methods.
Column:

Month = MONTH([Model built Date])

Measure:

Nearest Average = 
 CALCULATE(AVERAGE('Table'[Model built time]),FILTER(ALL('Table'),[Month]=MONTH(TODAY())))

Difference = ABS(SUM('Table'[Model built time])-[Nearest Average])

Nearest Value = 
Var _mindiff=MINX(FILTER(ALL('Table'),[Month]=MONTH(TODAY())),[Difference])
Return
IF([Difference]=_mindiff,SUM('Table'[Model built time]))

Is this the result you expect?
