Prestashop Discount table Module/Modul Prestashop.

What we need is a module for the Prestashop ecommerce platform and I'll start with the structure, after which I'll get into details of functionality. This module needs to allow me to create a table for discounts, specified only in percent, based on quantity of order, and said table should be seen in both Back Office and Front Office, inside the product page. What it needs to do, inside Back Office, is to let me have and create up to 999 tables, with discounts showed only in percent that applies to the base price of any product I want, 9 fields for each table, in which I can assign up to 9 customer groups that I already have, and the possibility to apply the whole table to groups of products, maybe even to categories of products. The two pictures I've provided show the way our table is listed inside the ERP, and the way it's listed inside our current website, so it can give you an idea. By how it looks inside the ERP, you will see discounts applied only in percent, and each row (ex: Zona X) as a customer group. The first two rows are quotes. First is symbol for "quantity from" and second is symbol for "quantity to", as in price for quantities from 0pcs. to 4pcs., then 5pcs. to 9pcs... etc. And under the quotes is the percent of the discount allowed for that range of quantity (where there's no value there's no discount). Inside the second picture (the one from our current website) you'll see it simplified, because it is only displayed for one customer group, and the percentage is applied instantly to the base price. Also, The table ID which can be exported from the ERP needs to be imported to each and every product from Prestashop so it will be associated with the desired discount table. This means that each product needs to have a discount table ID and a possibility of "inactive" (if no ID) for those products which don't have a discount table.
