Scenario is like that :
For UI:
While creating the invoice
1. User enter line items details like quantity, unit price etc and also enter tax amount manually in line items.
2.User enter the freight amount- freight is taxable.
2.User notice that total tax - tax after freight field recalculated automatically based on the tax amounts entered in line items and tax calculated on freight.
can it possible to create the invoice with same tax calculations as done in UI by user??????????????????????
Thanks...
