Answer 1

Try this, with an external query:

select
    *,
    sum(horas_uteis) as soma_horas
from (
    select
        dbo.FN_CALC_HORAS_UTEIS(s.SolData,min(l.LogData)) as horas_uteis
        datepart(month,s.SolData) MesID,
        datename(month,s.soldata) Mes,
        datepart(year,s.soldata) Ano
    from Solicitacao S
        left join usuario U on (U.UsuID = S.UsuIDResponsavel) 
        left join Status ST on S.SolStatus = ST.CodStatus
        left join Log L on L.LogSolID = s.SolID and (l.LOGDESCRICAO like '%1057%' or l.LOGDESCRICAO like '%3343%')
    where
        S.proid in (2)
        and S.UsuIDResponsavel in (1776)
        and s.SolStatus <> 9
        and convert(date,s.soldata) between '01-01-2018' and getdate()--and s.SolID = 65513
) as X
group by MesID, Mes, Ano
