Hi @Syndicate_Admin ,

Which connection mode does the data source you connect to adopt? For the DATEADD function, if it is in the Direct query mode, there may be performance problems, leading to errors.

Here is the reference document link:DATEADD function (DAX) - DAX | Microsoft Docs

Please make sure to use this function correctly and change the connection mode before trying again. If the problem is still not resolved, please let me know immediately, looking forward to your reply.

Best Regards,
Henry

Hi,

I am not sure how your data model looks like, but in my opinion, you need to have dim-date table.

And then, please try to write something like below.

Variations =
VAR current_value =
SUM ( factpagmb[valor facturado] )
VAR previous_value =
CALCULATE (
SUM ( factpagmb[valor facturado] ),
DATEADD ( 'your dim-date table'[date column], -1, MONTH )
)
RETURN
DIVIDE ( current_value - previous_value, current_value )

@Syndicate_Admin , Dateadd work on date.

so [Date].mes is not correct.

Also, prefer to date table in such case

example

last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))

if needed you can use date as date add
