Debt Aging

Hi, vytas 

Based on your description, I created data to reproduce your scenario.

Table:

You may create a measure as below.

Debt Age in  Days = 
var _accountsrecievable = SELECTEDVALUE('Table'[AccountsRecievable])
var _date = SELECTEDVALUE('Table'[Date])
return
IF(
    _accountsrecievable = 
    CALCULATE(
        SUM('Table'[Sales]),
        FILTER(
            ALLSELECTED('Table'),
            'Table'[Date]<=_date
        )
    ),
    COUNTROWS(
        FILTER(
            ALLSELECTED('Table'),
            'Table'[Date]<=_date
        )
    )
)

Result:

Best Regards
