Calculations by Rank

Would the below work for you?
Var = VAR nextRank = Table1[Rank] + 1 VAR differnce = CALCULATE( VALUES(Table1[Value]), FILTER(ALLEXCEPT(Table1,Table1[Type]),Table1[Rank] = nextRank) ) - Table1[Value] RETURN IF( differnce >= 0, differnce, BLANK() )Anonymous -
The entire code block is your calculated column. Documentation on using VAR can be found @ https://docs.microsoft.com/en-us/dax/var-dax and a nice example article can be found @ https://www.sqlbi.com/articles/variables-in-dax/

You're missing closing ' ) ' in a couple places.
Copy -> Paste my code and replace 'Table1' with 'Primary_ID' or try formatting multi-line by clicking ALT + ENTER so you can see your opening and closing Parentheses ' ( ' & ' )' respectively a little easier.

Many thanks Chris.
I'll give it a go!
It almost works Chris.
However this is the result I'd really like;
Primary ID Type Date Value Rank Var Type A20170101 Type A 01/01/17 100 1 0 Type A20170201 Type A 01/02/17 110 2 10 Type A20170301 Type A 01/03/17 125 3 15 Type B20180101 Type B 01/01/18 90 1 0 Type B20180201 Type B 01/02/18 95 2 5 Type B20180301 Type B 01/03/18 105 3 10 Type B20180401 Type B 01/04/18 120 4 15 Where the Var for Rank 1 is alway 0 as there is no lower rank. The var for rank 2 onwards is the value of rank 2 less rank 1, value of rank 3 less rank 2 etc.
Sorry to be a nusiance!

Var = VAR prevRank = Table1[Rank] - 1 VAR differnce = Table1[Value] - CALCULATE( VALUES(Table1[Value]), FILTER(ALLEXCEPT(Table1,Table1[Type]),Table1[Rank] = prevRank ) ) RETURN IF( differnce < Table1[Value], differnce, 0 )Here's my code...
= VAR prevRank = Primary_ID[Rank] - 1 VAR differnce = Primary_ID[Value] - CALCULATE( VALUES(Primary_ID[Value], FILTER(ALLEXCEPT(Primary_ID,Primary_ID[Type],Primary_ID[Rank] = prevRank ) ) RETURN IF( differnce < Primary_ID[Value], differnce, 0 )
and here's the error I get...
