From Dax to Power Query

Hi there,

I am calculating a column using the above-mentioned logic in DAX:

Last 24 hr Raw SAIDI =
SUMX(
FILTER(‘Fact Table’ , ‘Fact Table’[EpochHH] >= EARLIER( ‘Fact Table’[EpochHH] ) - 47 && ‘Fact Table’[EpochHH] <= EARLIER( ‘Fact Table’[EpochHH] ) ), ‘Fact Table’[30 Mins Raw ])

I want to convert the above DAX formula into power query language. I am not sure is there any alternate for earlier and sumx functions in the query language. Could anyone help me in converting above formula into query language?
