DAX Filtering help in a measure

[JonArnold]

Hi I am trying to work out how to use a filter in a measure using DAX & I am going round in circles.

I have a table that contains : ISSUE TYPE NVA_UNITS and a few other columns

I want to create a measure that will SUM the NVA_UNITS column (this is a Float data type)

the measure must also filter the sum so that it only returns the data with ISSUE TYPE "Qualität" ISSUE TYPE is data type varchar(50)

I have a Direct connection to an SQL database I want to create a measure that will return just the values that are issue type Qualität & SUM the number of UNITS affected. so far I have tried many queries and i've just not got the knowledge

I expect its a simple thing - I just need to find out how.

heres the code I tried last

NUMBER OF DEFECTIVE UNITS = SUMX( FILTER (WFT_DATA,'wft_data'[Issue_type] =[Issue_type]'Qualität'),(WFT_DATA[NVA_UNITS]))

I get the syntax is incorrect Hoping someone can help

Hi @JonArnold 
Perhaps something like this?

NUMBER OF DEFECTIVE UNITS =
SUMX (
    FILTER ( WFT_DATA, WFT_DATA[Issue_type] = "Qualität" ),
    WFT_DATA[NVA_UNITS]
)
