Calculations with virtual table

Hello everyone,   I am working with expenses dataset. This dataset contains 4 columns: the unique id, item id (which can appear multiple times in case few payments have been made for the same item)...

    Thanks for the reply from lbendlin and Greg_Deckler, please allow me to provide another insight.
    Hi cursty ,

    Please try the following dax.

    Perc_Rank = 
VAR _tb = CALCULATETABLE(SUMMARIZECOLUMNS('Expenses'[item_id],"Expense",[Expenses]),ALL())
VAR _expenses = VALUE([Expenses])
VAR _lower = IF(COUNTROWS(FILTER(_tb, [Expense]<_expenses))=BLANK(),0,COUNTROWS(FILTER(_tb, [Expense]<_expenses)))
VAR _higher = IF(COUNTROWS(FILTER(_tb, [Expense]>_expenses))=BLANK(),0,COUNTROWS(FILTER(_tb, [Expense]>_expenses)))
RETURN
DIVIDE(_lower,_higher+_lower,0)


    The result is as follows, hopefully it will meet your needs.


    Please see the attached pbix for reference.

    Best Regards,
    Dengliang Li

I am not sure if I understood your question, but for this measure I didn't use any mapping besides Calendar Table, which is needed to define the dates range.

 

Below is more simple formula with RANKX function (user for var 'ranking' which is returning me 1 for every item on the list)

Perc_Rank2 =
var maxdt = max('Calendar'[Date])
var mindt = edate(maxdt,-36)+1
var items =  SUMMARIZE(FILTER(Expenses, Expenses[payment_date] IN CALENDAR(mindt,maxdt)), Expenses[item_id], "Value", SUM(Expenses[paid_amount]))
var currentvalue =  CALCULATE(SUM(Expenses[paid_amount]), Expenses[payment_date] IN CALENDAR(mindt, maxdt))
var total = COUNTROWS(DISTINCT(SELECTCOLUMNS(FILTER(ALLSELECTED(Expenses), Expenses[payment_date] IN CALENDAR(mindt, maxdt)), "UniqueID", Expenses[item_id])))
var ranking = RANKX(items, currentvalue,,ASC)
RETURN DIVIDE(ranking, total)*100
