    Accumulate balance shown by date

      I would like to display the balance from the first dump to a specific date. Not every date has transactions. I want to look up the closest day before the date I enter in the selection in a report in QV and display the balance.



      Date             Balance

      5/5               9,000

      5/9               7,000

      5/18             4,000

      5/23             5,000

      I want to enter date 5/12/16 and get the response $7,000, which was the balance on 5/9/16 when the item was last touched. Note - there were no changes for this item between 5/9/16-5/18/16.

          May be like this:


          FirstSortedValue({<Date = {"$(='<=' & vVariable)"}>}Balance, -Date)


          Here vVariable will be driven by an input box or calendar box object

            Hi Matthew,

            Try this code, it will give what might look like an odd data model and you can tidy it up if you want but it's good to leave it as it is so you can get to understand how the IntervalMatch function works.

            Add a listbox for Date and a text box with the formula =Only(Balance) and play around with it:



            LOAD * INLINE [

                Date, Balance

                5/5/2016, 9000

                5/9/2016, 7000

                5/18/2016, 4000

                5/23/2016, 5000




            TempMinDate: //Get the start date for making a calendar


            Min(Date) as StartDate

            Resident Balances;


            Let vStartDate = PEEK('StartDate',0,'TempMinDate');// start date held in this variable

            DROP Table TempMinDate;




            Date as From,

            Date(RangeMin(Today(),Peek('Date',RecNo(),'Balances') -1)) as To,

            //The above line peeks ahead one record in the Balances table to see the To Date and subtracts 1.

            //If Peek does not return a value (when reading last record and there is no next record to peek) Today() is returned.


            Resident Balances;


            Drop Table Balances;


            Calendar: // Make a simple calandar of dates from start to today


            Date(TempDate) as Date;

            LOAD IterNo() + $(vStartDate) -1 as TempDate

            AutoGenerate 1 While IterNo() + $(vStartDate) -1 <= Today();



            IntervalMatch(Date) LOAD From, To Resident Periods; // This matches each date in the calendar to a time period
