We have a peculiar situation and we are trying different approach to solve it.
We have 2 VB apps that is a invoice form with a Header (Clients or Vendors info), Details (inventory items to sell or purchase) & Footer (subtotal, discounts, tax, freight and Total transaction). Both apps works exactly the same with difference that one for Sales Invoices for Clients and the other is for Purchase Order (PO) placed for Vendors (suppliers).
The problem that this presenting is when we delete or insert a line. The apps has to recalculate in order to present the line correctly within the Detail Grid.
Is there a better way of working with this?
