Can you give me a hint ?
pcena_bd_last30days2 = CALCULATE(SUM(movement[pcena]); movement[datum]>NOW()-30; movement[datum] <= NOW())
I tried to rewrite this with function datesbetween, but It did not work.
Hi Pstanek,
According to your description, you need a moving sum for latest 30 days, right?
If that is the case, here is a blog which describes hwo to do it step by step, please refer to the link below to see the details.
[3 Month Moving Sum Units Sold] =
CALCULATE([Units Sold],
DATESINPERIOD(Calendar[Date],
LASTDATE(Calendar[Date]),-3, Month
)
)

@pstanek In order to use time intelligence functions you need to have a date table related to your fact table. It would appear in your DAX function that you are referencing the same table.
Is it the table with only one column --dates ?
@pstanek Here is a thread which describes how to create a dynamic data table in PBI. It is a table that relates to a date in your fact table, and allows you to filter on other date parts (YR, MO, etc).
http://community.powerbi.com/t5/Desktop/Possible-Tip-Trick-Dynamic-Date-Dimension-Table/td-p/8462
There are numerous other examples out there.
It can have as many columns as you like but it needs one column with an unbroken range of dates (i.e. every date within the range with no dates skipped). People frequently add other columns such as Month and Year in order to use those groupings in their visuals, but that depends on your goals with this.

@pstanek Try this Measure... let me know
pcena_bd_last30days = CALCULATE ( SUM ( movement[pcena] ), DATESINPERIOD ( movement[date], LASTDATE ( movement[date] ), -30, DAY ) )
