FX-SCH-A-001063: Give each included tax exactly one rate

In short

Error: fails the selected checks.

FX-SCH-A-001063 means a tax included in a line's net unit price has no ram:RateApplicablePercent element, or has more than one. Make sure each ram:IncludedTradeTax block contains exactly one rate element for the applicable tax.

What it means

Each ram:IncludedTradeTax inside the line's ram:NetPriceProductTradePrice must contain exactly one ram:RateApplicablePercent. This rule counts the elements; it does not check the rate's value.

Why it matters

The required structure gives each included tax one place to state its rate, rather than omitting or repeating the rate element.

How to fix it

Check ram:IncludedTradeTax under ram:SpecifiedLineTradeAgreement/ram:NetPriceProductTradePrice on the affected line. Add the missing ram:RateApplicablePercent or remove duplicate rate elements, keeping the correct percentage for that tax. Export the corrected file and check it again.
