Oracle ERP- Supplier Audit - Important Points

After Supplier Is Updated, Alert On AP_SUPPLIERS Table Is Triggered Twice (Doc ID 1969553.1)

As part of enabling Oracle Alert functionality, the following trigger is created on the AP_SUPPLIERS table:

create trigger TEST_SUPP_UPD_ALERT_AU AFTER UPDATE on AP.AP_SUPPLIERS for each row
begin
insert into XXTEST_SUPP_ALERT_UPD values (:new.VENDOR_ID, :new.LAST_UPDATE_DATE);
end;

When supplier data is updated through the Supplier Master pages, multiple rows are inserted into the table XXTEST_SUPP_ALERT_UPD. The expectation is that only one row would be inserted.

Please explain / provide fix.
