Double Values

[Yannick_M]

Hello

I need help on a table.

I would like to add a calculated column that gives me back a D or R value.
R if the value is not double.
D if the value is doubled

Here are the columns

id users	Room	Year	Column measured
id111	1	2010
id333	1	2010
id1111	1	2011	D
id333	2	2011	R

i know the algorithm, but i dont scrive this in dax

i must to look if my room users is same than one year ago, if yes the result will be D or not then result is R

i think to use parallellperiod or sameperiodlast year, but i'm blocked on filter to use that

Sorry for my english

i hope someone will can to help me

Regards

Hi @Yannick_M 

you can try to create a new column with this:

Column =

VAR CurrentID = TableName[ID]

VAR CurrentRoom = TableName[Room]

VAR CurrentYear = TableName[Year]

VAR _count=

COUNTROWS(

    FILTER(

        TableName,

        CurrentID = TableName[ID]

            &&CurrentRoom = TableName[Room]            

            &&CurrentYear = TableName[Year]+1

    )

)

RETURN IF(_count=1, "D","R")

i tried and it worked like this:
