Question in PO tax and how is apllies to a PO

Hi,

I have a question in PO tax and an example is as follows:

PO unit Pirice 10

PO Quantity 10

Total Value 100

Tax Code applied to Po Line = 10% non recoverable (Recovery Rate is "0")

Does system consider the PO value as 110 and pay the supplier 110?

Or will the PO value will be 100 and the 10% tax will be considered seperately?

Can I have any user guide for the complte PO tax process and how it applies to PO.

Best Regards

Jaliya
