Without any warranty, you can try, if it doesn't work let me know, I'll delete my answer

create function getSumBSen(@pfcode number, @pdcode number, @pSen number) returns number
as

begin
     declare @r number;
     select 
         @r =sum(t2.t_shab + t2.t_rooz) 
     from 
         tbl1 t2 
     where 
         t2.FCode = @pfcode 
     and t2.DCode = @pdcode 
     and t2.sen <= @pSen
     group by t2.FCode, t2.DCode;

     return (@r);
end;


select 
    t1.sen, 
    sum(t1.d1) as d1, 
    sum(t1.d2) as d2, 
    sum(t1.d1 + t1.d2) as d_sum,
    Round((sum((1000*(t1.d1+t1.d2))/(9500-getSumBSen(t1.FCode, t1.dcode, t1.sen)))),1) as SSS 
from 
    tbl1 t1
where 
    t1.FCode = 81 
and t1.DCode = 1 
group by 
    t1.sen;

memento:

• Function creation

added, it won't let me actually fix the code because my edit is too short. So I had to write some more miscellaneous junk so that the code fix will be accepted.
