FILTER TABLE BASED ON ANOTHER TABLE

[MarketingGerens]

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.

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])))

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])
