You can make a calculated measure in PowerPivot to handle this. If you want to get the cumulative sales for all time you can do this:

    CALCULATE(     SUM( FactSales[SalesAmount] ),
    FILTER(
        ALL( DimDate) ,
        DimDate[Datekey] <= MAX( DimDate[Datekey] )
    )
)

If you want to be able to select certain time period (ex: running total for selected weeks or months) you can do this:

 CALCULATE( SUM( FactSales[SalesAmount])  ,
                 FILTER(
                    ALLSELECTED( DimDate),
                    DimDate[Datekey] <= MAX( DimDate[Datekey] )
                )
    )
