I need to customize the tax invoice report with the following changes:
1. Create a separate tax invoice report (Copy).
2. Change the heading to 'Estimation' instead of tax invoice.
3. Remove the tax column from the table and combine the tax amount to the unit price. In a manner that the table will only contain the unit price column (including the tax amount). And no separate tax column must be shown).
Rest all will be same as in the tax invoice report
