Odoo 11 has sort of a trap for newbies when it comes to using the top-right Wizard (Inventory Configuration step-by-step) to configure the system. When you open the Wizard  > Your Warehouse you have the link "Edit its details or add new ones" and this link automatically takes you to a new record creation page, one would assume that creating the new warehouse is needed but then after saving you realize you already have a warehouse in the system. This is a design flaw in my opinion.

Anyways, you can't just simply delete the new warehouse record, there are multiple other records created that locks the warehouse record. Deleting the warehouse isn't easy to do because the error message is not clear as to what needs to be deleted first or its exact location.

I would like to suggest that if a record is essential for other records that the user be given the option to delete all of them, or at the very least change the Wizard to alert the user that a record already exists when such obstacles are present if one wants to reverse the record creation. 

Please advise on the steps to delete a warehouse in V11.

Thank you.
