    Description

      In the current implementation of the first_value function, it's not allowed to have more than one (1) order by column, as so:

      select distinct
      first_value(kastr.DEWNKNR) over ( partition by kastr.DEKTRNR order by kastr.DETRADT, kastr.DEVPDNR )
      from RTAVP_DRKASTR kastr
      ;

      Error given:

      FAILED: SemanticException Range based Window Frame can have only 1 Sort Key
