Filtering error based on two columns

Hi,

 

I have the below dax expression and am trying to filter based on two rows however I get an error with the second filter that states
"A Function Filter has been used in a true or false expression"

Can someone explain to me the logic behind what im doing and why it's wrong.

Below is my dax measure

-Crew NA. = CALCULATE(COUNT(FACT_DELIVERY[CREW_QTY]),
FILTER(ALL(FACT_DELIVERY[CREW_QTY]),FACT_DELIVERY[CREW_QTY]<2)
&&
FILTER(ALL(FACT_DELIVERY[STOP_TYPE]),FACT_DELIVERY[STOP_TYPE] <> "C"))

Below is an example table:

Crew_qtystop_type
1c
1a
2a
3a

Hi OsmanEmi,

could you change the && to , and try again?

 

-Crew NA. = CALCULATE(COUNT(FACT_DELIVERY[CREW_QTY]),
FILTER(ALL(FACT_DELIVERY[CREW_QTY]),FACT_DELIVERY[CREW_QTY]<2)
,
FILTER(ALL(FACT_DELIVERY[STOP_TYPE]),FACT_DELIVERY[STOP_TYPE] <> "C"))

 

The && function returns a TRUE or FALSE based on whether the conditions are met. by using the "," instead you are adding another filter to your calculate function, instead of turning it into a TRUE/FALSE.

 

Best regards,

Tim

Hi @OsmanEmi ;

You're using the "&&" inbetween two FILTER() statements.

"&&" doesn't work in the way that it says "Do this AND do that".
It basically says "This has to be TRUE and this other thing also has to be TRUE"

Try this instead:

-Crew NA. = 
CALCULATE(
COUNT(FACT_DELIVERY[CREW_QTY]) ,
FILTER(ALL(FACT_DELIVERY),FACT_DELIVERY[CREW_QTY]<2 && FACT_DELIVERY[STOP_TYPE] <> "C")
)

Hi timg,

This worked thank you very much.
Is it possible to explain why this worked as opposed to my method?

Hi Osman,

I included an explanation as an edit in my first reply just now. Does this clarify the difference sufficiently?

Best regards,

Tim
