LTM in column

Hi Anonymous ,

Try this:

Columna =
CALCULATE (
    SUM ( 'FORMACION'[Horas Curso] );
    FILTER (
        ALLSELECTED ( 'Maestra Fechas'[FECHA] );
        'Maestra Fechas'[FECHA]
            IN DATESINPERIOD (
                'Maestra Fechas'[FECHA_PERI];
                'Maestra Fechas'[FECHA];
                -12;
                MONTH
            )
    )
)

If it doesn't work, please share me a dummy pbix file for test, only with necessary part, removing sensitive information and replacing real data with dummy data. It is suggested to upload your file to OneDrive for Business and then paste the link here.

Best Regards,

Icey
