I would like to do a distinct count of values on one table based on fields defined in another table, i am able to achieve this easily using SQL statements but i am unable to convert it into DAX as is used on power BI measures. Here is the SQL that i would use to count;
SELECT COUNT (DISTINCT F.TAXPAYER_ID) FROM DIM_TAXPAYER D, FACT_REGISTRATION F WHERE D.TAXPAYER_ID = F.TAXPAYER_ID AND D.IS_MIGRATED = 'Y' AND D.IPAGE_PROCESSED = 'Y' OR D.IS_MIGRATED = 'N';
Basically i want to count distinct taxpayer id's in the Fact_registration table that meet the criteria specified from the DIM_TAXPAYER table How can i convert this into a DAX expression?

Hi @Kevin_Gitonga,
Assuming that you have two tables like below and there is a relationship between the two tables.
Then you could create the measure refer to the formula below.
distinct_cout = CALCULATE ( DISTINCTCOUNT ( 'Table F'[ID] ), FILTER ( 'Table D', 'Table D'[ID] = RELATED ( 'Table F'[ID] ) && 'Table D'[IS_MIGRATED] = "Y" && 'Table D'[IPAGE_PROCESSED] = "Y" ) )
Here is the output.
In Power BI, "&&"means ''And'' and "||" means "OR". You also could use AND and OR functions in dax.
If you still need help, please share some data sample and your desired output so that we could help further on it.
Best Regards,
Cherry
