Question on discount calculated Tax for AP invoice

Hi All,

I wondered if it is possible to setup E-tax in a way that it calculates financial discounts on the tax line only.

For example:

I have an item line for 2500 and 21% VAT (Discount = 2%)

AP transaction should give

Item   2500

Tax      514,5

Total invoice  3114,5 

Any idea how I can set this up? In my opinion, changing the taxable basis is not an option as financial discount can differ from supplier to supplier.

Thank you,
