Running Total

sorry jahida,

i typed it wrong now there is no errors with formula but Running totals increased from 100% to 100.05% for every item in the Table.

here is what i did, as you said

First i chnged,

TotalGS = CALCULATE(SUM('Fact'[Gross Sales CY]),ALL(DimItem[ItemNumber]),ALLSELECTED(DimItem))

and then

RunningTotal = SUMX(FILTER(CALCULATETABLE(SUMMARIZE('Fact',DimItem[ItemNumber],"Contr",[GSContribution]),ALLSELECTED(DimItem[ItemNumber])),[Contr] >= MINX(VALUES(DimItem[ItemNumber]),[GSContribution])),[Contr])

Note: ItemNumber is different column and ItemKey is different column in DimItem

           I have Itemkey in both Fact and DimItem on which i have joined.

           ItemKey is Unique and ItemNumber can repeat 

                                                                                   DimItem Ex: ItemKey  ItemNumber  Company

                                                                                                              1                101                 A

                                                                                                              2                101                 B

                                                                                                              3                101                 C

Does this fact have any effect on the formula
Please help me. Try to look at the image i am getting 100.05% now
