Get next 3 row values for current row

I already got the solution for the next table with Power Query (grouping, indexing, combining, expanding, etc.), but when I load all the data, Power BI can't process it, it takes hours without gettin...

    Hi Anonymous ,

     

    If you want a measure in table visual, parry2k’s solution is proper and great.

    But if you want actual column in table, We can create following calculate columns to meet your requirement.

     

    Next 1 = 
var x = CALCULATE(MIN('Table'[Sequence]),FILTER('Table','Table'[Sequence]>EARLIER('Table'[Sequence])))
return
CALCULATE(MAX('Table'[Value]),FILTER('Table','Table'[Sequence]=x))

     

    Next 2 = 
var x = CALCULATE(MIN('Table'[Sequence]),FILTER('Table','Table'[Sequence]>EARLIER('Table'[Sequence])))
return
CALCULATE(MAX('Table'[Next 1]),FILTER('Table','Table'[Sequence]=x))

     

    Next 3 = 
var x = CALCULATE(MIN('Table'[Sequence]),FILTER('Table','Table'[Sequence]>EARLIER('Table'[Sequence])))
return
CALCULATE(MAX('Table'[Next 2]),FILTER('Table','Table'[Sequence]=x))

     

    And the result like this,

     

     

    BTW, pbix as attached.

OK, I'm missing how you get from Source to Results, can you explain that? I am assuming Source is your source data and includes Sequence and Value columns and that Results is what you want to end up with or am I mistaken?

    Hi Greg,

    That's right. Columns "Sequence" and "Value" are the source data, and results are what I need.

      Comment: The numbers in the "Sequence" column are illustrative, because they are the result of previous grouping commands. I use that column only to preserve date/time stamp, removed from this last table. I removed all unnecessary columns to avoid excessive processing time.

        Anonymous here you go, you can surely merge these measure to not create sequence measures

         

        Next 1 Sequence = 
VAR __currentRow = SELECTEDVALUE ( Next[Sequence] )
RETURN CALCULATE ( MIN ( Next[Sequence] ), ALL ( Next) , Next[Sequence] > __currentRow )

Next 2 Sequence = 
VAR __currentRow = [Next 1 Sequence]
RETURN CALCULATE ( MIN ( Next[Sequence] ), ALL ( Next) , Next[Sequence] > __currentRow )

Next 3 Sequence = 
VAR __currentRow = [Next 2 Sequence]
RETURN CALCULATE ( MIN ( Next[Sequence] ), ALL ( Next ) , Next[Sequence] > __currentRow )

Next 1 = 
VAR __sequence = [Next 1 Sequence]  
RETURN CALCULATE ( SELECTEDVALUE ( Next[Value] ), ALL(),  Next[Sequence] = __sequence )

Next 2 Sequence = 
VAR __currentRow = [Next 1 Sequence]
RETURN 
CALCULATE ( MIN ( Next[Sequence] ), ALL ( Next) , Next[Sequence] > __currentRow ) 
* DIVIDE ( __currentRow, __currentRow )

Next 3 Sequence = 
VAR __currentRow = [Next 2 Sequence]
RETURN CALCULATE ( MIN ( Next[Sequence] ), ALL ( Next ) , Next[Sequence] > __currentRow )
 *
DIVIDE ( __currentRow, __currentRow )

Value Max = SELECTEDVALUE( Next[Value] )

         

        and here is the output
