Topic: Differenciate dates
The Supplier's invoice date has not to be necessarily the same date of the generated GL transaction. F.i, if today (12/Aug) I receive a invoice dated on 20/Jul, the GL transaction must be dated on 12/Aug, nevertheless the invoice must to preserve its original date.
I suggest add a date field to specify the GL transaction date in the "Supplier invoices" form. So, invoice and transaction will have its proper date.
