Hi,

what about exception block, e.g.

begin
  select SUP_NO into sn from sup_tran
         	where 
         	TRAN_DATE=vs.DOC_DATE
          AND TRAN_NO1=d
          AND (LINE_NO=vs.LINE_NO or line_no is null);
 exception
   when no_data_found then
     -- do what necessary here
end;

Open in new window

otherwise you could first check whether there are records in recordset using count

 
select count(SUP_NO) into sn from sup_tran
         	where 
         	TRAN_DATE=vs.DOC_DATE
          AND TRAN_NO1=d
          AND (LINE_NO=vs.LINE_NO or line_no is null);

if sn > 0 then
  select SUP_NO into sn from sup_tran
         	where 
         	TRAN_DATE=vs.DOC_DATE
          AND TRAN_NO1=d
          AND (LINE_NO=vs.LINE_NO or line_no is null);
end if;
