Hello,
I am trying to retrive the previous value of a row, using the knowledge I read from other posts about this topic.
But, the data I get is incorrect. I dont understand why.
My table name is Data, and it has the following columns:
- I for Index. Running number (1,2,3,...)
- Number of sales
I want to calculate: Number of sales [I] - Number of sales [I-1], for each row
This is the dax I am using:

Hi @Justiy ,
I have created a simple sample, please refer to it to see if it helps you.
Create a measure.
Sales Gr =
VAR Cur_Index =
MAX ( Data[data] )
VAR Pre_Index = Cur_Index - 1
VAR Pre_Value =
CALCULATE (
MAX ( Data[Sales] ),
FILTER ( ALL ( Data ), Data[data] = Pre_Index )
)
VAR Cur_Value =
CALCULATE (
MAX ( Data[Sales] ),
FILTER ( ALL ( Data ), Data[data] = Cur_Index )
)
RETURN
Cur_Value - Pre_Value
If I have misunderstood your meaning, please provide more details with your desired output and pbix file without priavcy information.

Hi,
Share some data to work with. Do you have a Date column in your dataset? Do you want a calculated column or a mesure solution?

Yes it works. Thanks.
My problem was that I needed to add to my filter - ALL() as you did.
