How to calculate the date difference between a existing column with date slicer "selected value"

Hi ALL,

I have a table with two date columns "ValueDate" and "EOMDate" (end of month date), I have taken the EOMDate in a date slicer and also able to capture the value selected from the slicer using below code with a Measure as below.

```ValueSelected = CALCULATE(
MAX(Remittance[Remittance.EOMDate]),

ALLSELECTED(Remittance[Remittance.EOMDate]))```

but I am unable to compare the measure "ValueSelected" with column "ValueDate".

I tried this first

`AgeMeasure = DATEDIFF(Remittance[Remittance.ValueDate],Remittance[ValueSelected],DAY)`

I got the below error

"A single value for column 'Remittance.ValueDate' in table 'Remittance' 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."

I tired the below as an alternative approach, which is throughing the same error , any advise will be much helpful.. Hearty thanks.

```AgeMeasure =
VAR MinVDate = MIN(Remittance[Remittance.ValueDate])
VAR MinVVD = DATEDIFF(MinVDate,Remittance[Remittance.ValueDate],DAY) // Getting the error Here
VAR SVMVD = DATEDIFF(MinVDate,[ValueSelected],DAY)
RETURN
SVMVD - MinVVD```

Re: How to calculate the date difference between a existing column with date slicer "selected v

It's not clear to me what you are trying to do here.  What a slicer does is filter your table.  The best way to understand this is to load your data into Excel, convert it to a table and then place a filter on the EOM column for the date you want.  This is what a slicer does.  Now that the table is filtered, what do you want to do?  The table has a filter on it so you are limited in what you can do to the filtered copy of the table.

So, still not really knowing what you want to do, it is likely that you will need 1 or 2 disconnected slicers that are on a table of dates. Click on this new slicer to harvest the value that the user selects.  This way you get the input without placing a filter on the table.

If you can provide some more information about the logic of what you are trying to acheive I could possibly help some more

Re: How to calculate the date difference between a existing column with date slicer "selected v

Example Data

 EOMDate ValueDate SelectedDate 12/31/2012 12/06/2012 10/31/2016 02/28/2013 02/21/2013 10/31/2016 08/31/2014 08/18/2014 10/31/2016 09/30/2014 09/14/2014 10/31/2016

Expected Output

 EOMDate ValueDate SelectedDate AgeValue 12/31/2012 12/06/2012 10/31/2016 1425 02/28/2013 02/21/2013 10/31/2016 1348 08/31/2014 08/18/2014 10/31/2016 805 09/30/2014 09/14/2014 10/31/2016 778

Note:
ValueDate: >> Column from the Source (SSAS Tabular model)

SelectedDate / ValueSelected : >> a measure calculated based on the date slicer built on "EOMDate" column

Hi @Anonymous,

Actually, you don't want to filter the data. You'd like to indicate the date instead. I would suggest you create a new table [EOMDate] that will provide the field of the slicer.

`SelectedValue = SELECTEDVALUE('Table'[EOMDate])`
```Measure =
DATEDIFF ( MIN ( 'Table1'[ValueDate] ), [SelectedValue], DAY )
```

Re: How to calculate the date difference between a existing column with date slicer "selected v

Thanks for your Great time..  it is working fine with "List" and "Dropdown" type of date slicer, but for my requirement I am using "Before" type of slicer where this "SelectedValue" is not working..

unfortunately, I need to filter the data to get whatever data available Prior to the date (EOMDate) as per the selection

any help is much & more appreciated..

Thanks,

Prabhu

Re: How to calculate the date difference between a existing column with date slicer "selected v

all I want to achieve is,

1) Need to filter the table based on the slicer selection (condition is to get the data prior to the date selected)

2) Need to find the date difference (age value ) from the date selected through "Before" date slicer.

Thanks,

Hi @Anonymous,

It's my pleasure. The measure could be useful in many scenarios. Please try it out.

`SelectedValue = Max('Table'[EOMDate])`
