Calculate Changes in Cycle over Cycle

[joshua1990]

Hi all!

I have a table with his structure:

Cycle	Week	Article	Value
A	2023-01	ABC	500
A	2023-01	ADG	600
B	2023-01	ABC	450

Now I would like to create a matrix that shows me the changes for each week vs the last cycle

Cycle	2023-01	2023-02
A	50	0
B	0	0
C	0	0

Since the value for Article ABC has changes by 50 for week 2023-01 in both cycles, this change should be displayed.

But how?

@joshua1990 , Create a separate Year week Table with distinct weeks(Say Dates), then week rank column should be able to help

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

These measures can help
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))
