Pretty much a mess now in my inventory. We didn't know this was going to be a problem prior to setting up Enterprise Inventory.

We added a custom field for the non-existent Default Site and Location - tedious but works. I think I will have to set up a new warehouse now that we know it won't get fixed. I understand that there are transactions tied to the "old" location but there should be an easy way to do this.

Maybe you could add a text warning that if you make a typo/enter anything wrong even once you live with it forever.
