Populate first value with the expanded column's value and rest with 0/null on merge query

I have two tables 

Table A - Has Product information (Product, Sub-Product Count)

Table B - Actually it's a sales table with (Sales Date, Brand/Product)

 

Requirement - I want third column on merge. But I only want to have third column to have values (no. of sub-product) to be populated for only first matching Product/Brand and rest to be '0' or null for the same Brand/Product.

 

The merge operation is applied based on 'Left Join' on column 'Brand' : Table B -> Table A

    Hello kushalt1996 

     

    I have a solution that involves PQ and DAX. Please follow the below.

    Sep 1:

    Add index to your table - b  And create a custom column by using [Brand]&Text.From([Index]).

    Step 2:

    Merge Table-b with table - a and pull the Min of index from Table - b. Again create a custom column like above.

     

    Step 3:
    Close and Apply and use a lookup to pull the Sub Product count.

    No of Sub Product = LOOKUPVALUE('Table- A'[Sub-Product count],'Table- A'[Custom],'Table - B'[Custom])

     

    Please let me know this solution is good with you and if you have any questions.
