@AccHarprS  as long as there have been some Inventory Transactions there’s no way to delete the Inventory Part. Also, changing the site cannot be done.

You would need to re-create the Inventory Part in the correct site also and you would need to transfer the serials in the correct site/warehouse - you can do that via Distribution Order for example. Or you can scrap the serials in the wrong site and re-do the transactions in the cotrrect site. Please also watch the accounting postings to make sure they’ll be correct in the end.

Ofcourse the interco setup between the 2 companies/sites should be done in order to be able to transfer the parts via Distribution Order.
