i have to tables, upon them i am creating list which aggregate the measure in a list.

i want to create running diff on rows.

attach picture.

Use this one instead. In a new column and not measure

DIFF = 
var previous = CALCULATE(FIRSTNONBLANK(Sheet1[count_student], Sheet1[count_student]), FILTER(Sheet1, Sheet1[ForeignYear]=EARLIER(Sheet1[ForeignYear] ) -1))
return IF(ISBLANK(previous),0, Sheet1[count_student]-previous)

IMage below:

i can't....

the count_student is a measure which count students...

so the column phrase can't see this measure.

this is the problem....

hi, @yogevz

After my test, you could use this formula to create a measure as below:

Measure = CALCULATE([Count_student measure])- CALCULATE([Count_student measure],FILTER(ALL(Sheet1),Sheet1[Foreign]=MAX(Sheet1[Foreign])-1))

Count_student measure is a measure which count students.

Result:

You can try this formula:

New_Diff = SUM(Sheet1[count_student]) - IF(MAX(Sheet1[ForeignYear])=1, SUM(Sheet1[count_student]), LOOKUPVALUE(Sheet1[count_student], Sheet1[ForeignYear], MAX(Sheet1[ForeignYear])-1))

Please try the following DAX formula:

DIFFERENCE = 
var previous = CALCULATE(FIRSTNONBLANK(Table[count_student];Table[count_student]);FILTER(Table;Table[ForeignYear]=EARLIER(Table[ForeignYear]) )) 
return IF(ISBLANK(previous);0; Table[count_student]-previous)
