Check article number - Note in case of duplicate article number

This small module checks the item number to see if it already exists. If it does, you will be informed graphically.
Nevertheless, the entry is permitted (example: you are creating a new product and the old one is still online).

If the item number has not yet been assigned, a green tick appears.

Optional: with lock - no duplicate item number possible (no extra charge, but only if installed by us).

Note for Modified Shops: this module is also available in the MMLC from version 2.0.5.1, including free updates.
