Can't get DAX Total / Sub Total to work!

[sachintandon84]

Here is my measure:

Cash Balance [GBP]:=VAR CorrectTable =
ADDCOLUMNS (
GROUPBY (
Projected_Cash_Balances,
Projected_Cash_Balances[Country],
Projected_Cash_Balances[Dates]
),
"Last Balance [GBP]", SUMX (
FILTER (
Projected_Cash_Balances,
[Index] = MAX ( [Index] )
&& LASTDATE ( Projected_Cash_Balances[Dates] )
),
[Balance [GBP]]]
)
)
RETURN
AVERAGEX ( CorrectTable, AVERAGE ( [Last Balance [GBP]]] ) )

Attached is my input table, and a pivot table. The cell highlighted in yellow is wrong... : (  (it should be 79,723)

Thanks in advance,

Sachin

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376

Also, this Quick Measure, Measure Totals, The Final Word should get you what you need:

Thanks for the suggested help.

I read through both links, but am still struggling with my specific problem.

The totals are not always wrong. Just wrong on some days....

With updated DAX below (but it is still not working....)  = [

Cash Balance [GBP]:=VAR CorrectTable =
ADDCOLUMNS (
GROUPBY (
Projected_Cash_Balances,
Projected_Cash_Balances[Country],
Projected_Cash_Balances[Dates]
),
"Last Balance [GBP]", AVERAGEX (
FILTER (
Projected_Cash_Balances,
[Index] = MAX ( [Index] )
&& [Country] = EARLIER([Country])
&& [Dates] = MAX([Dates])),
[Balance [GBP]]]
)
)
RETURN
SUMX ( FILTER(CorrectTable, [Dates] = MAX([Dates] )), [Last Balance [GBP]]])

ok, problem now solved

VAR CorrectTable =
    ADDCOLUMNS (
        GROUPBY (
            Projected_Cash_Balances,
            Projected_Cash_Balances[Country],
            Projected_Cash_Balances[Dates]
        ),
        "Last Balance [GBP]", AVERAGEX (
            FILTER (
                Projected_Cash_Balances,
                [Index]
                    = MAXX (
                        FILTER (
                            Projected_Cash_Balances,
                            [Country] = EARLIER ( [Country] )
                                && [Dates] = MAX ( [Dates] )
                        ),
                        [Index]
                    )
            ),
            [Balance [GBP]]]
        )
    )
RETURN
    SUMX (
        FILTER ( CorrectTable, [Dates] = MAX ( [Dates] ) ),
        [Last Balance [GBP]]]
    )
