Distinct Count of weeks based on sales measure

[Anonymous]

I have to tables sale table and calendar table In calendar table I have weeks column. I have a calculation of sales in my sales table I want to get the number of weeks based on my sales measure.
I don't want all number of weeks but only the number of weeks where sales have been made according to my calculated sales measure.
Thanks.

Hi @Anonymous 

The trick is to iterate the Sales table and count the number of weeks.  We can use SUMMARIZE to do that as it can access the extended table.

week count = 
COUNTROWS(SUMMARIZE('Sales','Date'[Week]))

@PaulOlding  Thanks for your reply
The thing is that sales is not a column its a calculated measure

@Anonymous The 'Sales' referenced in my measure is the name of the table with all the sales amounts (ie the fact table)

@PaulOlding  this does not work can we try some other logic?

@Anonymous In that case some more information would be helpful.  See this post https://community.powerbi.com/t5/DAX-Commands-and-Tips/How-to-Get-Your-Question-Answered-Quickly/m-p/1626726#M32906
