Currently, prepayment invoice (printout) only shows the GL Account code which is not useful when we are sending the prepayment invoices to customers who requested for them.

They would like to see the items, quantities and unit prices shown as per the sales orders and posted sales invoices. This is also a request due to audit requirements from the customers' auditors to tie the relationship between the different documents using the details instead of showing a GL Account code that is useless to them.
