Repeating an information when blank but within groups

‎10-06-2021 01:47 PM

I have a database of purchased items and their prices. But, on some months, there's no purchase of some items. The idea is to repeat the price of the last purchase until we buy the item again. This repetion shouldn't be limited. I've tried using the DAX code below, but I only get the value to repeat for one time. I must note that the variable Price is a column created directly on the table in Data View. Can someone help?

 

  • Within a group of items
  • Repeat the previous data of price if there wasn't a purchase on the current month
  • Repeat until the next purchase

 

Current code:

 

Pre_Value =
   VAR ItemGroup = 'Table'[Item]
   VAR Date1 = 'Table'[Month-Year]
   VAR Pre_Date = PREVIOUSMONTH('Table'[Month-Year])
   VAR Prev_Val = CALCULATE(MAX('Table'[Price]),FILTER('Table','Table'[Item]=ItemGroup),FILTER('Table','Table'[Month-Year]=Pre_Date))
RETURN IF('Table'[Price]=BLANK(),Prev_Val,'Table'[Price])

 

Outcome example:

 

ItemPriceMonth-YearPre_Value
100519 2021-10 
100793 2021-06 
100793952021-0795
100793672021-0867
100793 2021-0967
100793 2021-10 

 

Expected outcome:

 

ItemPriceMonth-YearPre_Value
100519 2021-10 
100793 2021-06 
100793952021-0795
100793672021-0867
100793 2021-0967

@rutealvesdc  find the attached pbix. It has the desired result in both calculated column and measure

_fdColumn = 
VAR _0 =
    CALCULATE (
        LASTNONBLANK ( t1[Date], 1 ),
        FILTER (
            ALL ( t1 ),
            t1[Date] <= EARLIER ( t1[Date] )
                && t1[Item] = EARLIER ( t1[Item] )
                && NOT ( ISBLANK ( t1[Price] ) )
        )
    )
VAR _1 =
    CALCULATE ( SUM ( t1[Price] ), FILTER ( ALL ( t1 ), t1[Date] = _0 ) )
RETURN
    _1
_fdMeasure = 
VAR _mxDate =
    MAX ( dt[Date] )
VAR _2 =
    CALCULATE (
        MAX ( dt[Date] ),
        FILTER ( ALL ( dt ), dt[Date] <= _mxDate && [_Price] <> 0 )
    )
VAR _3 =
    CALCULATE ( [_Price], ALL ( dt ), dt[Date] = _2 )
RETURN
    _3
