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]).NaveenGandhi_0-1685376464368.png

Step 2:

Merge Table-b with table - a and pull the Min of index from Table - b. Again create a custom column like above.NaveenGandhi_3-1685376590030.png

 

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])
