Understood, but what happens if the customer has been using a code of:
... 998, 999, 1000
They then left the code null on the next two items and your function
stuck in 1001 and 1002. Then they figured out what they wanted to do
with the codes on their end but wanted the items to have codes of 1002,
1001 for the items you coded 1001, 1002 respectively.

Unique within a customer, which is what your code implied or unique
across all customers?

Well, I am with David on this, either the customer is totally in charge
of the codes or you are. The thought of mixing systems gives me a headache.
