Specific Price Applied to: ... Bulk on DB

[victorglobal]

Hi,

We have succesfully imported all the specific prices we needed for all of our products (>13000 specific prices) after some manipulation of our old server and migrating it to PS. But we found out that after doing that the discounts are applied to the price with taxes included instead of the price without taxes, wich in our case should have been exactly the opposite, my question is:

In wich table of the DB does pretashop knows that certain specific price of certain product is applied to the price with or without taxes?, I've imported the specific prices to the ps_specific_price table but there is no column where to specify it.

I manually modified one product to apply the discount to the price without taxes and still can't find where in the DB is it stored that the specific price is for the price without taxes.

Thanks in advance.
