distinct count with condition

[clarissa]

Hello  How can I count distinct order_no which are only coming from specific traffic sources  (google, mail, bing)? So the distinctcount happens based on a pre-filtered data set (traffic sources). Thank you!

It sounds like a job for CALCULATE

CALCULATE(DISTINCTCOUNT('Orders'[order_num]),'Orders'[source] IN { "google", "mail", "bing" })

depending on the structure of your report and what the external filter context is you may have to add an ALL('Orders')

Hi @kentyler 

Thanks for your answer.

The data model is:

- unique order number is in 1 table.

- Google Analytics order number table ("google_analytics_order_no") is combined with this unique order number (1 to *)

- ERP data ("sales") is combined with unique order number (1 to *). My formula looks like this:

# Order PMKT = CALCULATE(DISTINCTCOUNT(sales[order_no]), FILTER(google_analytics_order_no, google_analytics_order_no[source_medium] = "google / cpc" || google_analytics_order_no[source_medium] = "bing / cpc" || google_analytics_order_no[source_medium] = "criteo / display" || google_analytics_order_no[source_medium] = "awin / affiliate" || google_analytics_order_no[source_medium] = "facebook / social_paid"))

when I count the numbers of Google Analytics I have more orders, which doesnt make sense:

# Order PMKT GA = CALCULATE(DISTINCTCOUNT(google_analytics_order_no[order_no]), FILTER(google_analytics_order_no, google_analytics_order_no[source_medium] = "google / cpc" || google_analytics_order_no[source_medium] = "bing / cpc" || google_analytics_order_no[source_medium] = "criteo / display" || google_analytics_order_no[source_medium] = "awin / affiliate" || google_analytics_order_no[source_medium] = "facebook / social_paid"))

Does this formula with the filter not work in my datamodel?

Thanks for your help, very much appreciated.

Best regards

Clarissa

Hi @clarissa ,

Try trouble shooting your DAX

Order PMKT = CALCULATE(DISTINCTCOUNT(sales[order_no]), FILTER(google_analytics_order_no, google_analytics_order_no[source_medium] = "google / cpc" )

See if the formula is returning the correct value for "google/cpc".

Also, remove all trailing spaces by Trimming this column in Query Editor.

Hi Harsh

Thank you for your feedback. Why do you think it is linked to the trailing spaces? I get numbers but the Google Analytics number is higher than the Sales Table Number, which doesn't make sense... Is the DAX Formula right or does it react differently if the distinctcount is applied on another table than the filter table?`

Thank you!

Hi @clarissa ,

Can you share a sample .pbix file.

Hi @harshnathani 

Unfortunately not, but here the data modell

Does that help? B2C_unique_order_number is joined with the 2 other tables with the order-no (1 to *)
