Hi
We've created a condition type ZMWS which is a copy of MWST but the calculation type is a Fixed Amount not percentage (Because it's used in interfaced sales orders where the tax value comes on amount from the other system)
Key users need usually to modify on these interfaced orders in SAP to add new posts. the problem occurs when the user fill only the condition value, he press enter, and then he fill the amount, in this case the condition base is not calculated (set to 0), the base is calculated only when we start by setting the amount.
Base = 0 => Blocked invoice with the error: " tax base in local currency is zero"
Any suggestions please to handle this issue ?
ZMWST :

Thank you
Kind regards
