I'm in the process of figuring out how to set things up to be able to use Intercompany Inventory Drop Ship. I'm currently testing things in sandbox, and am trying to use the Automatically generate Representing Entities feature. I made sure all the necessary prerequisites are enabled, per the Prerequisites to Automatically Create Representing Entities page, and have tried this process a few times now without success.

The problem is that it creates the Vendors successfully, but when it attempts to create the Customers, the result is Failure with the error message "You may only change the name from the Vendor version of this record."
