Starting Balance based on Date Slicer

Hello,

 

I am having trouble with using a date slicer to calculate starting balance for a cash balance.

 

So, I want to have a date filter that will allow me to calculate a dinamic starting and end balance.

- Starting balance is calculated as Movements in period previous to the Start Date (Date From).

- End balance is calculated as Starting balance + movements in between selected period.

 

The date slicer will ideally be a range (Date From to Date To), where, if I change the start date, my opening balance will increase/decrease.

 

I include below a simple table and the expected results, in case it helps with understanding what I would love to achieve.

DateValue
01/01/201950
01/06/2019100
31/12/2019-20

 

Based on these values, some calculated examples will be:

Start date: 05/01/2019. End date: 30/06/2020.

Starting Balance: 50

Movements: +80

End Balance: 130

 

Start date: 01/09/2019. End date: 30/06/2020.

Starting Balance: 150

Movements: -20

End Balance: 130

 

Do you have any guidance I could use?

 

Thanks a lot!!

    Ok we can do this with 3 measures.  I've made some assumptions, such as that you have a date table.

    Movements = SUM('YourData'[Value])
    Start Balance = var StartDate = FIRSTDATE('Date Table'[Date])
var output = CALCULATE(
	[Movements],
	ALL('YourData'),
	'YourData'[Date] < StartDate
)
RETURN
output
    End Balance = var movements = [Movements]
var startBalance = [Start Balance]
RETURN
startBalance + movements

    You make sure you have date calendar. End balance is nothing but cumulative

     

    Starting value = 
var _min =minx(Table,Table[date]))
CALCULATE(SUM(Table[value]),filter(date,date[date] <=_min)


Cumm value = CALCULATE(SUM(Table[value]),filter(date,date[date] <=maxx(date,date[date])))

Cumm value = CALCULATE(SUM(Table[value]),filter(date,date[date] <=maxx(date,endofmonth(dateadd(date[date]),-1,month))))

    To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
