skip a row and rewrite the same values from 2nd row

[Anonymous]

Hello, I have a small question. I have a column X with 1 2 3 4 5 6 as numbers and i want a column to be added with Y  as the same as X but 1st row should be skipped in Y when comparing to X. Like the following one.

X      Y

1   

2      1

3      2

4      3

5      4 

6      5

        6

c

Can anyone please suggest me the solution with a DAX code or else anything?

Hi @Anonymous ,

Test the below:

Table2 = DISTINCT(UNION( SELECTCOLUMNS('Table',"X",'Table'[X]),SELECTCOLUMNS('Table',"X",0)))

Y = IF (
        Table2[X]=0,
       CALCULATE(MAX(Table2[X]),ALL(Table2)),
IF (
    CALCULATE (
        MAX ( 'Table2'[x] ),
        FILTER ( ALL ( Table2 ), Table2[x] < EARLIER ( Table2[X] ) )
    ) = 0,
    BLANK (),
   
        CALCULATE (
            MAX ( 'Table2'[x] ),
            FILTER ( ALL ( Table2 ), Table2[x] < EARLIER ( Table2[X] ) )
        )
    )
)
