Update fields with SUM from a table - Help

Hello guys,

I tried to run this script but it complains:

 An aggregate may not appear in the set list of an UPDATE statement.

Could you give me a help on this?

Thanks a lot

update arfin set arfin.VALBAX=sum(bx.VALINI), arfin.VALJUR=sum(bx.VALJUR), arfin.VALDESC=sum(bx.VALDESC), 
                 arfin.VALOUTROS=sum(bx.VALOUTROS), arfin.VALMULTA=sum(bx.VALMULTA) from arfin_detalhe bx
       where arfin.codcad=bx.codcad and arfin.numdco= bx.numdco and arfin.codempresa = bx.codempresa
and bx.codcad = 7 and bx.numdco = '06042018-01'  and bx.codempresa ='E001'

Use a derived table as the source instead.

update a 
set a.VALBAX=bx.VALINI /* plus other SETs */
from arfin a
join (
   select  codcad, numdco, codempresa, valini = sum(VALINI) /* plus other sums */
   from arfin_detalhe 
   where codcad = 7 and numdco = '06042018-01'  and codempresa ='E001'
   group by codcad, numdco, codempresa
) bx on a.codcad=bx.codcad and a.numdco= bx.numdco and a.codempresa = bx.codempresa

Or can use a CTE (Common Table Expression)
;with CTE_Update as
(  select codcad, numdco, codempressa
          , sum(VALINI) as VALINI
          , sum(VALJUR) as VALJUR
          , sum(VALDESC) as VALDESC
          , sum(VALOUTROS) as VALOUTROS
          , sum(VALMULTA) as VALMULTA
   from arfin_detalhe 
   where codcad = 7 
   and numdco = '06042018-01'  
   and codempresa ='E001'
   group by codcad, numdco, codempressa    
   update a set VALBAX=C.VALINI
   from arfin a
   inner join CTE_Update C on C.codcad = a.codcad, C.numdco = a.numdco, C.codempresa = a.codempresa

But test first by doing a select * from arfin a inner join CTE_Update .....
