What happen to this issue? Is there any update how it went through? My case is almost the same with this, i need to include doctype i created “Lot Reservation Entry” in payment reference so that i can add payment entry against “Lot Reservation Entry”. Hope someone could help. Currently, the standard doctypes included in reference_doctype are the following only: Sales Order, Sales Invoice, Journal Entry, Dunning. I wanted to include Lot Reservation Entry.
