DAX Formula

Can someone help me with a simple formula to calcualte the value of the last year (which is YYYY number not a full date) ?

I tried the following formual but it isn't returning any values:

LY = Calculate(AVERAGE(Table[Value]), FILTER(ALL(Table), Table[YEAR] = Table[YEAR]-1))

Hi @aghonaim,

 

Sorry. Recreate it as a calculated column.

The question is: "what do you want to see at the grand total"? Showing the value for 2012 looks a good compromise, but if you want to fix it, you first need to decide what to show there. At the grand total - being no year in the selection - the very value of "last year" is undefined.


Have fun with DAX!

Makes sense ?

Is there a measure can do that ? if yes, which one is better/faster ?

Only thing i see your formula is missing to work is a MAX call:

 

LY = Calculate(AVERAGE(Table[Value]), FILTER(ALL(Table), Table[YEAR] = MAX ( Table[YEAR] ) -1 ) )

Can the totoal be fixed ?

@aghonaim,

 

The total is showing LY value of 2012. Because you have used MAX in your DAX. so, it picks Max(Year).

 

Just Create a calculated measure with following formula,

 

Last Year = LOOKUPVALUE(Table3[Value],Table3[Year],Table3[Year]-1) 

 

you will get the required Value.

 

Thanks,

Siva

I got this error:

A single value for column 'Year' in table 'Table' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.

Hi @aghonaim,
