Structure Defaults doesn't work while Copying Sales Order to Sales Invoice


I have set up the Form Default for Sales Invoice to choose the “Deals - Account” GL as default.

Yet, when we duplicate a Sales Order to Sales Invoice, any remaining structure default settings work, aside from the choice of the “Deals - Account” GL. it is left clear, and I really want to physically choose the GL account.

Am I missing something here?

You need to furnish more information. Post Edit screen shots of your Form Defaults for sales invoices and the specific transactions involved, both the sales order and resulting sales invoice. Also, understand that there is no “duplicate” function in Manager. Do you mean Copy to?
