FILTER TABLE BASED ON ANOTHER TABLE
Hi
I have this 2 tables on my dashboard:
TABLE1CUSTOMERS
CUSTOMERID | PRODUCTIDPURCHASE | REGISTER_DATE
________________________________________________________________
101 | C01 | 20/11/2019
102 | C02 | 20/12/2019
TABLE2PRODUCTS
PRODUCTID | LAUNCH_DATE
___________________________________
C01 | 19/11/2019
C02 | 22/11/2019
I would like to filter CUSTOMERID's out based on whether DATE1 is earlier than DATE2 to see how many new customers bought a product. I was thinking to do this using the DAX below:
NEW CUSTOMERS =
CALCULATE(
COUNT(TABLE1CUSTOMERS[CUSTOMERID]), FILTER('TABLE1CUSTOMERS','TABLE1CUSTOMERS'[REGISTER_DATE]>'TABLE2PRODUCTS'[LAUNCH_DATE])
)
but this is giving me an error because I can't use the FILTER function by referring to another table. Can somebody help me?
Hello,
As you are trying to access the rows of a table on the one side of the relationship from the many side of the relationship, you need to use RELATED function.
NEW_CUSTOMERS = COUNTX(FILTER(Cust,Cust[REGISTER_DATE]>RELATED(Products[LAUNCH_DATE])),Cust[CUSTOMERID]).
Though using CALCULATE function too we could achieve the same result.
This is yet another way of achieving it, without using calculate.

You can have a new column in table1customer, that can help you to solve the problem
minx(FILTER('TABLE2PRODUCTS','TABLE1CUSTOMERS'[REGISTER_DATE]>'TABLE2PRODUCTS'[LAUNCH_DATE] && 'TABLE1CUSTOMERS'[PRODUCTID ]='TABLE2PRODUCTS'[PRODUCTID ]),'TABLE2PRODUCTS'[LAUNCH_DATE])Appreciate your Kudos.

It seems your tables are related by product ID, you need to use RELATED() when referring to THE other table columns.NEW CUSTOMERS = CALCULATE(COUNT(Table1[ID]), FILTER('Table1','Table1'[Register Date]>RELATED(Table2[Launch Date])))
