Hi,

[Quoted] Add an exception to pick up the problem, eg. EXCEPTION
  WHEN OTHERS
-- whatever ---

This will pick up any error in the entire procedure, so you could isolate date problems by writing a function that only does the date conversion, eg. ELSE
  var_check_date := check_date_valid(tr_rec.inventory_end_date);   IF var_check_date IS NULL THEN
-- whatever ---
END; FUNCTION check_date_valid (tx_date_in IN VARCHAR2)

          RETURN DATE IS
  dt_return DATE;
BEGIN
  dt_return := TO_DATE(tx_date_in, 'YYYYMMDDW');

  • in your example, the quotes were missing. -- RETURN dt_return;

EXCEPTION
  WHEN OTHERS
    null;
-- or message or whatever --
