Create a SUM measure that sums conditionally (based on a value in another column)

[gvg]

Hi experts,

I have been using another table (tableB) to sum specific values in tableA using the following simple DAX:

Sum amount = CALCULATE ( SUM ( tableA[Amount] ), tableB[NewProducts] )

However this works only when Product_code in both tables is numeric. When Product_code is text, I get this error message: Cannot convert value "300a" of type Text to type True/False". How do I go around this?

My sample tables are like this:

tableA                                                    tableB
Product_code    Amount                                    Product_code
123a             100                                      125a
125a             120                                      300a
200              130
300a              90

OK, looks like this measure solves the issue:

Sum amount = CALCULATE ( SUM ( tableA[Amount] ), DISTINCT ( tableB[NewProducts]) )

Try

Sum Amount =
CALCULATE (
    SUM ( tableA[Amount] ),
    FILTER ( TableA, TableA[Product_code] = TableB[NewProducts] )
)

Well, this syntax in Filter does not seem to be valid?
