Post insert error

Question

hi all
i have a form for sale entry. i want to insert into an another table
when i save its contents.
i used a post insert trigger for this.
but the form has a detail block. and so this insert as many records as this block has.
the form has the following blocks.
sal_master(master block)
     sal_id
     sal_date
     cust_id
sal_detail(detail block)
     sal_id
     qty
     price
post insert trigger
declare     
     a number; -- ledger no
     b number; -- customer id
     c date; -- entry date
     d number; -- credit
begin
     -- insert into customer ledger
     select nvl(max(l_id)+1,1)
     into a
     from cust_led;
     b:= :sal_master.cust_id;
     c:= :sal_master.sal_date;
     d:= :ser_detail.total;
     insert into cust_led (l_id, cust_id, e_date, credit)
     values ( a, b, c, d);
exception
     when no_data_found then
     raise FORM_TRIGGER_FAILURE;
END;
on block level and form level the result is same.
i want to insert only one entry in the table for multiple records
in this form.

Answer 1

move this trigger to your sal_master(master block level) . this will only insert 1 record.
