FX-SCH-A-000336: At most one included tax entry per net price

In short

Error: fails the selected checks.

FX-SCH-A-000336 means a line's net price in your Factur-X or ZUGFeRD Extended file contains more than one included tax entry (ram:IncludedTradeTax). Remove extra entries within the affected ram:NetPriceProductTradePrice.

What it means

Each ram:NetPriceProductTradePrice under a line's ram:SpecifiedLineTradeAgreement may contain at most one direct ram:IncludedTradeTax child. This check concerns tax entries inside the price, not tax entries in the line's settlement.

Why it matters

This part of the price structure supports no more than one included tax entry. Repeating the element exceeds the limit even if the entries describe the same tax.

How to fix it

Check the included tax details for the affected line's net price. Keep no more than one appropriate ram:IncludedTradeTax inside its ram:NetPriceProductTradePrice and remove repetitions. You do not need to add an entry solely for this rule. Export the file again and recheck it.
