Problem when create sequence [message #377411]

Hello everybody,

I try to make sequence with each record when I'm in first record line number will show '1' and when I'm in second record line number will show '2'. for my problem I use when-new-record-instance with this code

BEGIN	
if :DT_BLOCK.LINE_NO  is null then
			if :DT_BLOCK.CNT_LINE is null then
				:DT_BLOCK.LINE_NO :=1;
        end if;
else 				:DT_BLOCK.LINE_NO := :DT_BLOCK.CNT_LINE +1;
end if;
END;

(:DT_BLOCK.CNT_LINE is use for sum record)

but my line number will change when I click to another record like if I want to change line number to '2' in second record I have to click to first record or clike 'detail button' to change to another page so line number will change to '2'

In another way I try to use another trigger
I use when-new-record-instance with this code:

if :DT_BLOCK.LINE_NO is null then
	:DT_BLOCK.LINE_NO:=:DT_BLOCK.CNT_LINE +1;
end if;

and when-mouse-click with this code:

if :DT_BLOCK.LINE_NO is null then
			if :DT_BLOCK.CNT_LINE is null then
				:DT_BLOCK.LINE_NO:=1;		  
        end if;
end if;

with this when I go to second record line number will change to '2' but when I choose customer_name from LOV line number will always return to '1'

how can I solve this problem? please help.

Regards,
aorlunla

All you've done is just too complicated. There's an easy way to do that, and it is called :SYSTEM.TRIGGER_RECORD. So, for every new record, you might create a WHEN-CREATE-RECORD trigger which would look like

:block.sequence_number_item := :system.trigger_record;

That's all.

Perhaps you'd want to read about other system variables as well; you might learn something new.
