## how to view rank change over time?

Hi,

I've got a category value (CAT) stratified into date periods divisions (DATE) (e.g. week 1, week 2 etc), I've created a measure to rank them by DATE the number of sales each CAT is making

e.g.

 CAT DATE SALES RANK A 1 10 3 B 1 20 2 C 1 30 1 A 2 10 3 B 2 20 2 C 2 30 1 A 3 40 1 B 3 20 3 C 3 30 2

I want to create an additional measure or table to show the change in rank from the minimum to maximum of date Value but I'm at a complete loss. I tried creating a second table with the intention of usings LOOKUPVALUE using min/max on the date field but you can't lookup to measures, only columns.

i.e.

 CAT RANK CHANGE A -2 B +1 C +1

You may create measures like below:

```Max_Rank =
CALCULATE (
[Rank],
TOPN ( 1, ALLEXCEPT ( Table2, Table2[CAT] ), Table2[DATE], DESC )
)
```
`Min_Rank = CALCULATE([Rank],TOPN(1,ALLEXCEPT(Table2,Table2[CAT]),Table2[DATE],ASC))`
`RANK CHANGE = [Max_Rank]-[Min_Rank]`
