On B2B eCommerce, the display invoices view does not display credit orders (invoices with negative amount), it only shows the debit orders (invoices with positive amounts). 

This is misleading information for the customer and causes additional questions and workload for the customer service team.

Back with release 10.0.35 both debits and credits were excluded from the invoice page in Ecom. Since 10.0.38 only debits are displayed on the Ecom invoice page; credits are not displayed.

We either need to show debit and credit orders or none of them.
