Where is the VAT ID stored(sending orders from PS to ERP) [SOLVED]

[mk2-pronat]

Hello,

I'm heaving trouble processing the order sent from PrestaShop to a ERP. Without going into to much detail, is there a place where PrestaShop stores the different VAT settings? Like if i create one VAT for 9% and another for 10% or 20% is there a specific ID created somewhere in PS database for the different VAT numbers?

The reason i'm asking is that they(the dev from ERP) said that the id of a new vat is different from some reason, but i only created a new one like before. 

I added an image of the VAT i'm talking about

Yes it is, and you don't even need to create a new one. Every time you edit an existing tax rule, the ID changes.

In back office you can see all the ID's for different tax rules, and then tax rules are associated to products as id_tax_rules_group column in the ps_product database table.

Thank you Daresh for your fast reply.

So i changed an old existing vat to the new percent  and created a new order, but it seems that the ERP prompts the same thing...

I've also noticed that whenever i edit an existing VAT and click save, it automatically ads a new ID to it in PrestaShop back-office as shown in the image i added. So how would i keep the same ID if every change creates a new one?

It's the Prestashop functionality to generate the new ID on the update as well. So can't do anything on the same. 

Finalize the taxes on the Prestashop and then update the Tax ID on the ERP system, then use the same.

And whenever you make changes in the taxes, you need to sync the Tax ID on the ERP System

Thank you both for the responses,i've learned something new about Prestashop today. Indeed this was the issue and it was solved.

So thank you again!
