Change the editing process for invoices so that each line item will prompt for both a "Discount %" and "Billback %" value.

 

This change also modifies the way the customer "Sales Discount %" is applied so that only the single highest deduction from the manually-entered "Discount %", the customer's "Sales Discount %" or an applicable promotion will be applied to the item.

 

The application of the discount has also been changed so that the deduction is taken off of the Unit Price rather than off the Extended Amount.

 

Update 5 Dec 2006:

Extended the implementation of this modification so that the "Discount %" and "Billback %" values may also be edited on existing invoice line items. Previously access to these values was restricted only to the process of adding new invoice line items.
