All of my contacts have a studio-created field called "Cust No.".
I was easily able to display this field on Sales Orders by creating a related field:
Customer -> Cust No. (selection path)
partner_id.x_studio_cust_no (technical name of related field)
However, all similar attempts to display this field as a related field on Invoices have failed. The most basic method that I assumed would work was:
Partner -> Cust No. (selection path)
partner_id.x_studio_cust_no (technical name of related field)
I have tried many different paths toward "Cust No." field including through delivery address, company, contact, transactions, etc. Nothing has worked.
Any help would be greatly appreciated.

@Niyas,
Thanks for sharing. However, this is adding the related field to a sales order...which I can already do. The problem I'm having is doing the same related field on Invoice. When trying to add to invoice, "Customer" is not available...and "Partner" (or any other attempted paths) don't work.
