DAX for Filtering a row of currency by a Date Created by a Measure

[NL-Nicolas]

Hi Power Bi Community!

Below is a screenshot of what I am trying to achieve, I have 2 tables using the same NetSales column. In the car above I want to show the difference for each row between both tables NetSales Column. I have tried so many different things and using 2 different tables to show the % change by date was all I had left for ammo! Recommendations on how to do This Week vs This Week Last Year welcome

Hi @NL-Nicolas ,

1.Please try to add an index column for two table:

Table1:

Table2:

2.add a slicer for with, and create a measure and add it into card visual

Differ =
VAR cur_index =
    SELECTEDVALUE ( Table2[Index] )
VAR cur_table1 =
    CALCULATE ( MAX ( Table1[NetSales] ), Table1[Index] = cur_index )
VAR cur_table2 =
    CALCULATE ( MAX ( Table2[NetSales] ), Table2[Index] = cur_index )
RETURN
    cur_table1 - cur_table2

@NL-Nicolas , With help from a week rank column in date/week table

Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)
OR
Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format

You can  measures like
This Week = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))
