Create a simple transaction with VAT exclusive
There is one aspect which needs to be considered in case of a transaction where the VAT amount is exclusive.
The total amount (e.g amount: CHF 7000.- VAT: 8% -> CHF 560.- -> CHF 7560.-) as well as the posting amount (e.g. CHF 7000.-)
needs to be supplied.
