Automate VAT on Expenses

Content

Dears,

I created a VAT for TAX RATE = 11%

I need to apply tax on Payables invoice based on the below rules:

1- "Supplier Registered in VAT? (Y/N)
AND
2- Goods/Service Type"

Example :

"The supplier is registered and submits an invoice with a good and a service.

The product is subject to VAT but the service isn't, so VAT will be paid only on the value of the good (= VAT is applicable on item level)"

Calculation: 11% x product amount only (supplier is registered and service isn't subject to VAT)

How to create and automate these rules? what to change in supplier profile?
