FX-SCH-A-000757: The tax representative can have at most one general identifier

In short

Error: fails the selected checks.

FX-SCH-A-000757 means the seller's tax representative has more than one direct ram:ID element. Keep at most one general identifier in that location, without confusing it with separately recorded global identifiers or VAT numbers, then recheck your file.

What it means

In the Extended profiles of Factur-X and ZUGFeRD, ram:SellerTaxRepresentativeTradeParty (BG-11) may contain zero or one direct ram:ID child. This count does not include ram:GlobalID or ram:ID inside ram:SpecifiedTaxRegistration.

Why it matters

The profile provides at most one general identifier field for the seller's tax representative. Other identifier types use separate elements.

How to fix it

Check the general identifier recorded for your seller's tax representative. Make sure ram:SellerTaxRepresentativeTradeParty contains at most one direct ram:ID. Remove duplicate general identifier elements or correct the export mapping if another type of number has been placed there. Do not remove separately recorded global identifiers or VAT numbers merely because this rule failed. Recheck the corrected file.
