Custom Trigger issues on PO_DISTRIBUTIONS_ALL table... null id?

Question

Hi...I have a custom after insert trigger on the PO_DISTRIBUTIONS_ALL table
It is having an issue with getting the req_distribution_id
I took out all the code and left in just a test, which only inserts the id into a test table. But it is always null! Can someone tell me why? Because there is an ID when created, and I see it after I query the table when it is finished. But I figured, after insert it will be there!
Below is the trigger...
create or replace
TRIGGER APPS.xxmc_po_distributions_auir
AFTER INSERT OR UPDATE ON PO_DISTRIBUTIONS_ALL
REFERENCING NEW AS new OLD AS old
FOR EACH ROW
DECLARE
v_trigger_location VARCHAR2(2000):= 'Declaration';
v_error_message VARCHAR2(2000);
BEGIN
delete from test_table;
insert into test_table values(to_char(:new.req_distribution_id));
END;
This enters null every time into the table. Why is that?

Answer 1

OK my new trigger has the dml statements in a procedure and it still fails. The ID is always null. Below is the trigger...why is the id coming up null???
:new.req_distribution_id should never be a null value in my opinion, right?
