J-BusinessDirectory - Creation of offers

In the offer creation form, which file can I edit to remove some fields?

Just for prices, for example, it appears:
- Price;
- Price base *;
- Base unit of price *;
- Special price;
- Special price base *;
- Basic unit of special price *;

* These fields I don't understood for what they serve !!? So how can I remove them? Only price and special price already meet what I want and need.

In the currency field too, I would like to leave automatic "BRL", or at least this currency is already selected.

In the location I would also like to remove some options ...

Anyway, I believe that in a single file I might be able to edit and remove all of that, but I can not find which file, what would it be?

Hi,

The base price and unit price are shown to show the base price of the offer.
E.g. You have the base price for 100g but your products are in kg. Your offer will be 10kg for $100 (100g for 10$)
You can remove the fields if you edit {joomla}/administrator/components/com_jbusinessdirectory/views/offer/tmpl/edit.php

You can set the main currency on general settings. This currency will be used if the currency is not set on offer.
