A product may have abbreviated names or modified descriptions during work. A stable internal reference allows you to link orders, stocks and documents without depending only on the text. Its usefulness requires consistent handling of variants and substitutions, avoiding ambiguously reused codes.
I propose to define what identifies the code and when a new one is needed. An item, variant, and packaging may require separate references. The criterion should be understandable to those who buy and those who prepare the work, with a link to the information of the suppliers.
In a hypothetical example, it changes the commercial description while the product remains the same. A stable code retains the connection to order history. If an essential feature changes instead, the management must make the difference from the previous version recognizable.
Periodic verification looks for duplicate references and missing links. The system improves when it facilitates day-to-day work without requiring informal interpretations. Consistent identification makes research and comparison more reliable, keeping what unites or distinguishes product information visible.
