The problem is that you have asked to summarize the data by grouping on
product description but you have also asked for a product code. The server
does not know if there is a one-to-one relationship between product
description and product code. Therefore, it does not know what product code
to use for each product description and,therefore, for each row in the
resulting data set.

The solution is to add product code to the GROUP BY clause. That way you
will get a resulting record for every unique product code-product
description combination and the server will know which product code to
return because it is the one being paired with product description in that
specific grouping.

The rule you violated is the one that requires all requested fields in the
output result set to be either the result of an aggregation function, such
as SUM(), or it must appear in the GROUP BY clause (so the server will know
what value to return).
