Previous Value from slicer selection

Hi, 

 

Wondering if anyone can help me on this one:

 

I have the following simple measure: 

Total = COUNTROWS('Fleet (Cars)')

In another table we have the labels for year ranges such as:

 

 

RangeIndex
2017-20181
2018-20192

 

When the user clicks the slicer, it shows the number of rows for that period, but I could also like to automatically show the previous period. I have tried with things like the following but to no avail.

 

Previous = CALCULATE(COUNTROWS('Fleet (Cars)');'Ranges'[Index]-1)

Any suggestions how I could achieve this?

 

Many thanks, 

 

Matt

Hi again, 

 

Just to let you know we've managed to figure it out with the following:

 

var a = CALCULATE(Max('Ranges'[Index])-1)
var b = CALCULATE(
DISTINCTCOUNT('Fleet (Cars)'[id]);
filter(
ALL('Fleet (Cars)');true());'Ranges'[Index]=a;) return b

Regards, 

 

Matt

Hi @Anonymous

 

Give this a shot

 

Previous =
CALCULATE (
    COUNTROWS ( 'Fleet (Cars)' ),
    FILTER (
        ALL ( 'Ranges'[Index] ),
        'Ranges'[Index]
            = SELECTEDVALUE ( 'Ranges'[Index] ) - 1
    )
)

Thanks @Zubair_Muhammad but getting a multiple column error on this one:

 

The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.

 

 

Hi @Anonymous

 

Could you show me a screen shot? or share the file?

How are the tables related?

Relation is a bidireccional one to many between the IDs of the ranges:
