cumulative total not summing up correctly

[Anonymous]

Hello,

I have written a measure for cumulative total, but it is not working properly for instance where the values are same for different entity.

Below is the snapshot. I have also shared PBIX file in below link(We transfer link).

Hi @Anonymous ,

Normally I would take a lot more time to explain what I did but I am in a real hurry so here is the solution:

Measure 2 = 
VAR _curRuleType = SELECTEDVALUE(Data[Rules Type])
VAR _filter = ALLEXCEPT(Data, Data[City], Data[Offence Count])
VAR _summaryTable = SUMMARIZE(_filter, [Rules Type], "TMargin", [Total Margin])
VAR _rankedTable = ADDCOLUMNS(_summaryTable, "Ranked", 
    VAR curRuleType = [Rules Type]
    RETURN
        RANKX(_summaryTable, 
            RANKX(_summaryTable, [TMargin], , DESC, Skip) +
            DIVIDE(RANKX(_summaryTable, [Rules Type], , ASC, Skip), COUNTROWS(_summaryTable) + 1),
        ,DESC,Skip)
        )
VAR _curRank = MAXX(FILTER(_rankedTable, [Rules Type] = _curRuleType), [Ranked])
RETURN
SUMX(FILTER(_rankedTable, [Ranked] >= _curRank), [TMargin])

Resulting in the following in your PBIX:

If you have any questions, please don't hesitate to ask and I will return tomorrow 🙂

Kind regards
