Dear community members,

thank you

Dear @mhmdAhmd, please check calculations in XML Implementation Standard

Below is relevant extract:

VAT category tax amount (BT-117) = VAT category taxable amount (BT-116) × (VAT rate (BT-119) ÷ 100)

VAT category taxable amount (BT-116) = Σ(Invoice line net amounts (BT-131)) + Document level charge amount (BT-99) − Document level allowance amount (BT-92)

Ok, I have a question, how can I validate that all my calculations are correct ?

is it just to get the invoice reported without errors or warnings makes its calculations correct?

like I have an invoice with an two items:

1- 26.09 (excl. VAT) => 30 (with vat)
2- 5.17 (excl. VAT) * 2 (for qty) => 11.89 (with vat)

the total with vat is 41.89 or 41.90 in other calculations
