In the Open customer view, it is possible to insert the field Method of payment from the customer (CustTable)
It is not possible to add the field Method of payment from the customer transaction (CustTrans) table even though you easily can change the Method of payment from the default value on the customer to a specific value on the invoice.
This means, that if have to do some follow-up work in this view, and are interested in seeing specifically which Method of payment an open invoice is posted with, then you have to open the invoice.
It is possible to insert other fields from both the CustTable and the CustTrans-table. Examples of these are Cash discounts, Payment specifications, and Payment schedule.
The idea for this wish is to make it possible to insert Method of payment from the CustTrans-table in the view Open customer invoices to have a more correct overview of how an invoice has been posted and not what is the default value on the customer.
