Running Totals on Selected Dates

[Robbief]

Hi 

I've looked, but can't seem to find a solution, and keep running down rabbit holes, so am reaching out for some help / direction on how to tackle this.

I have a Transaction Table, with Sales with Dates and Time.  I've got two additional supporting tables for Date and Time respectively.  I've created a measure for Running Total of Transactions throughout the day, and would like to compare any two days of my choosing.

My initial idea is to create another Date table, and create two seperate measures, one for Date 1, and the other for Date 2, and have both measures appear on the same graph....  But I appear to be coming unstuck...   

This is the measure I am using (Non Date Filtered):

Cumulative Sales (Calendar 1) = IF (

    COUNTROWS ( 'Transaction Line' ) > 0,

    CALCULATE (

        [Sum Transactions],

        FILTER (

            ALLSELECTED ( 'Time Table'[Time] ),

            'Time Table'[Time] <= MAX ( ( 'Time Table'[Time]) )

        )

    ),

    BLANK ()

)

IS my approach right?  If not, what approach would you consider?

Thanks for the pointer.  In the end I used USERELATIONSHIP to achieve exactly what I wanted:   

**Except for Dynamically naming the series based on the slicer date selection............  😞

I could see that...  But am not sure on how to create a measure on a table that isn't connected in the Schema - Do I create a "virtual join" in the code (Using something like Lookupvalue) ?

@Robbief If you are choosing 2 dates that are both connected to the same fact table via something like slicers, then this will cause problems. You would need those tables to be disconnected tables (no relationship) for that to work.
