Filter on empty rows

[Susan12344]

Hi Power BI community!

I hope someone can point me in the right direction on this. My situation is as following:

I have two tables with product names. One of them is a table with all the available products and the other is the actual bought products by customers.

I want to show within a certain time frame which products were not bought by customers. So basically text values that are available in table 1 but not in table 2. I'm a bit stuck on which filter to use and I'm not googleing the right question. Can anyone point me in the right direction? Much appreciated!!

Hi @Susan12344 ,

Please try below steps:

1. below is my test table

Table1:

Table2:

Table3:

create with below dax formula

Table3 = CALENDAR(FIRSTDATE(Table2[Date]),LASTDATE(Table2[Date]))

2. below is the model

3. create a measure with below dax formula

Measure =
VAR min_date =
    MIN ( Table3[Date] )
VAR max_date =
    MAX ( Table3[Date] )
VAR tmp =
    CALCULATETABLE (
        VALUES ( Table2[Product] ),
        Table2[Date] >= min_date,
        Table2[Date] <= max_date
    )
VAR cur_pt =
    SELECTEDVALUE ( Table1[Product] )
RETURN
    IF ( cur_pt IN tmp, 0, 1 )

3. add a slicer with Table3[Date], add two table visual with Table1 field and Table2 fields, add measure to a table visual filter pane that created with Table1 field

4. below is output

Please refer the attached .pbix file.
