Adding/Updating GTINs to already created Item is not creating Change Order Approval process

Summary:

I have created and approved an Item through NIR process, Now I am trying to add the GTIN to this approved Item and clicked on Save to change Order I am getting error as Item **** cannot be added to a change order because no changes were made.

I know Item DFFs are not supported for Item change order, I need to know what all attributes are not supported for Change order process
