[Anonymous]

Hi,

I have to add custom column called "last week" with the following expression : 

(departure_ >= date_add(current_date(), -$Weeks (4)*7) and departure<current_date())

Can someone please help me with dax expression.

Thanks in advance.

Hi, @Anonymous 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table:

You may create a measure as below.

Visual Control = 
IF(
    MAX('Table'[Departure])>=TODAY()-28&&
    MAX('Table'[Departure])<TODAY(),
    1,0
)

Then you may put the measure in the visual level filter to filter the result.

Best Regards

Allan

Hi,

could you please describe the exact logic of your calculation? What are you trying to achieve? Would this be an IF statement? It's easier to help if you can provide us with more context/background a sample dataset even?
