Creating new records while querying existing record

Question

Hi,
I have one master - detail form.
First i created 1 record. Request ID is the primary key. Now request id generated. For ex.: 10
Request Id, date, requestor , location, status fields are in header block.
In lines block, i hv some other fields.. and one field called 'Activity'.
While creating first record, the activity will be 'New'.
Then i'll query the record '10'.
when i'm changing the activity 'New' into 'Upgrade', it should create new record with new request ID.
How to do this?
I hv written procedure that, i'm taking field values to local variables. Then assigning the local variable values to field values.
It is not creating as new record. It overwriting the existing record with new values. Existing record is missing.
Pl. give steps.
Thanks

Hi,
Okk, you will have to do two things. Create two trigger on block level on which you want to do your changes.
1. First trigger. (PRE-UPDATE)
In pre-update trigger u will have to write the complete insert statement into the same table with new req id. like
DECLARE
vReqNo DATA_TYPE;
BEGIN
SELECT MAX(REQ_ID)
INTO vReqNo
FROM your_table;
INSERT INTO your_table
(req_no, fields....)
VALUES
(vReqNo, :forms_values);
END;
2. Create 2nd trigger on block level (ON-UPDATE)
write in this trigger
NULL;
for viewing the inserted record. What u have to do is in ON-UPDATE after null; create one timer NO_REAPEAT.
and in timer u will have to set the block property to req_id = generated_req_id_from_pre_update_trigger and
execute_query;
hope it will work...
