Error

FX-SCH-A-000323: The line total basis amount can appear only once

In short

Error: fails the selected checks.

FX-SCH-A-000323 means a header-level tax entry in your Factur-X or ZUGFeRD Extended file contains more than one ram:LineTotalBasisAmount. Keep the correct value and remove duplicate or unnecessary entries, then export and recheck the file.

What it means

Each ram:ApplicableTradeTax under ram:ApplicableHeaderTradeSettlement may contain at most one ram:LineTotalBasisAmount in the Extended profile. The test counts elements within each tax entry. It has no condition limiting it to VAT and does not check the amount's calculation.

Why it matters

The Extended profile provides one place for this amount within each header-level tax entry. Repeating the element exceeds that structural limit.

How to fix it

Find the affected ram:ApplicableTradeTax inside ram:ApplicableHeaderTradeSettlement. Check the intended line total basis amount and keep at most one ram:LineTotalBasisAmount in that tax entry. Do not add repeated values together merely because several elements are present. Export and recheck the file.
