To get the net value by subtracting discount from total

Question

Hi all
I have an issue in the report I am using oracle reports 6i
i have a total_services field which is a summary column (CS_1) AND a discount_field which is a formula column (cf_1)
the requirement is to get total_services - discount value
i created another formula column NMAD1 with the following formula (sub_dis_ser is a placeholder column of NUmber datatype i created)
function NetserFormula return nUMBER is
begin
   :sub_dis_ser  := :CS_2 - :CF_1;
   return(:sub_dis_ser);
end;this is the code for CF_1, in which i have included a placeholder column CP_6 i created
function DiscFormula return Number is
begin
   if  nvl ( :Dis_per1 ,0 ) <> 0     then
                  :CP_6  :=  :TOT_INV_SER - (  :TOT_INV_SER * nvl (:Dis_per1,0) /100 ) ;
   elsif  nvl ( :DIS_VAL1  ,0 ) <> 0    then
            :CP_6  :=  :TOT_INV_SER - nvl ( :DIS_VAL1 ,0 ); 
   Else
             :CP_6  :=  :TOT_INV_SER ;
           Return ( null  ) ;
   End if ;
           Return ( null  ) ; 
end;i am getting blank data
kindly guide me
thanking in advance

Answer 1

Hi,
Are you getting any compilation errors in this function..
function DiscFormula because what is that you wanted to perform in this if condition?
  if  nvl ( :Dis_per1 ,0 )  0     then ....your if statement seems to compare nothing like this   if  nvl ( :Dis_per1 ,0 ) > 0     then... Regards,
