    Create a calculated column on the cashflows table like

    Cashflow USD =
VAR CurrentCurrency =
    RELATED ( 'Fund mapping'[Currency] )
VAR CurrentDate = 'Cashflows'[Date]
VAR Rate =
    LOOKUPVALUE (
        'FX rates'[FX rate],
        'FX Rates'[Date], CurrentDate,
        'Fx Rates'[Currency], CurrentCurrency
    )
RETURN
    'Cashflows'[Cashflow] * Rate

    Thank you, this has worked. 

    For my own understanding, is there any way to do this as a measure? Or is that not fit for this purpose.

      I don't think that would suit in this situation. There are several advantages of doing it as a column. The calculation only happens once, during data refresh, and so the end user will not see any performance problems, and with a column you can then create other measures on top of that. Having to calculate it on the fly for every visual would not give good performance.
