RANKX Measure

Hi ccakjcrx. Thanks for your reply.

I've tried as you described but it's not working for me. The IF condition could be or not, never mind about that. The problem is with the RANKX.

Here is my model:

This is the Sales measure:

Ventas IMS = 
SWITCH(
	VALUES('Selector Medida'[Medida]);
	"USD";
	'Medidas VentasIMS'[Ventas IMS MUSD];
	"ML";
	'Medidas VentasIMS'[Ventas IMS ML];
	"UN";
	'Medidas VentasIMS'[Ventas IMS MUN]
)

And "USD" as example:

Ventas IMS MUSD = 
SWITCH(
	VALUES(
		'Selector Período'[Período]
	);
	"YTD";
    CALCULATE(
        SUM(
            'Ventas IMS'[ImporteVendidoUSD]
        );
        DATESYTD(
            'Período IMS'[Fecha]
        )
    );
	"MTH";
    SUM(
        'Ventas IMS'[ImporteVendidoUSD]
    );
	"MAT";
    CALCULATE(
        SUM(
            'Ventas IMS'[ImporteVendidoUSD]
        );
        DATESINPERIOD(
            'Período IMS'[Fecha];
            LASTDATE(
                'Período IMS'[Fecha]
            );
            -1;
            YEAR
        )
    )
)

And the RANKX:

Ranking Grupos = 
RANKX(
    ALLSELECTED('GruposIMS');
    ROUND('Medidas VentasIMS'[Ventas IMS];0)
)

I've deleted the IF condition.

I'm still getting 1 position of rank for all options of "Grupo".

Any other advice?
