NetSuite support documentation re: global account mapping restricts says "Although accounts receivable and accounts payable accounts can be mapped, the mapping is ignored for transactions that include entities such as invoices and bills." What is the purpose of this restriction? My accounting team wants to be able to map accounts payables accounts and not have that ignored on vendor bills, but NetSuite says the only way to do that is get rid of the "Name" field, but then our AP aging reports are incorrect. Why would this not work? Is it just a dumb NetSuite defect?

It's intentional. Make accounts with a different type to enter on bills and invoices
