    Hi , dfs29 

    Thanks for your quick response!

    According to your description, you want to "For example in line 1 (cf below) I have no values in column 2 so I want to divide by 1".

    You can try to use dax code :

    Measure = var _t =ADDCOLUMNS( CROSSJOIN( ALLSELECTED('Table'[time]) ,  ALLSELECTED('Table'[user case])) , "mv avg" , [moving average])
var _cur_time = MAX('Table'[time])  
var _column =  MAX('Table 2'[user case])
var _t2 = FILTER( _t,[time] =_cur_time && [user case] = _column)
var _value= SUMX(_t2,[mv avg])+0
var _count  =CALCULATE( COUNTROWS('Table 2') , 'Table 2'[user case] <> "AVG")
var _count2 =COUNTROWS( FILTER(_t , [time]=_cur_time && [mv avg] <> BLANK()))
var _sum =SUMX( FILTER( _t , [time] = _cur_time) , [mv avg])
return
IF( _column= "AVG" , _sum/_count2  ,_value)

Hello v-yueyunzh-msft , 

 

thank you very much for taking the time to explain it to me it seems to be correct.

However, what should I do if I want to divide by the number of non-empty columns?

 

For example in line 1 (cf below) I have no values in column 2 so I want to divide by 1
in line 3 I have a value for column 1 and a value for column 2, so I divide by 2

do you have an idea please

 

 

 

 

Kind regards
