Hello, cousinitt13 

    Table.AddColumn(
       fact_mach_speed_TEST, "stoptransid",
       (x) => Table.SelectRows(
           fact_downtime, 
           (w) => 
            w[sk_pk_machine_rewinder] = x[sk_pk_machine_rewinder] and 
            x[reptime] >= w[begtime] and 
            x[reptime] <= w[endtime]
       ){0}[stoptransid]?
    )
