By default, Bluestore Live numbers all your categories, products, regions etc itself, and attaches a code to each item. When you switch to Bluestore, you may already have your own numbering system that you want to transport. So, you can change the way Bluestore deals with each individual entity to suit your previous numbering protocols.
In your web console, navigate to the main menu item 'Settings', and then to the drop down menu item 'Numbering'.
On this page you'll see a list of all the entities, along with their method of being numbered.
Scroll through to find the name of the entity you want to edit. Double click (or highlight/ Edit), and bring up the edit dialogue box.
You'll find options to set the numbering to auto, or, alternatively manually set what the next number should be.
