FX-SCH-A-000827: The delivery party's tax registration needs one identifier

In short

Error: fails the selected checks.

FX-SCH-A-000827 means a tax registration block for the delivery party contains no ram:ID element or contains more than one. Make sure each ram:SpecifiedTaxRegistration block has exactly one ram:ID.

On this page

What it means

For each ram:SpecifiedTaxRegistration under ram:ShipToTradeParty in the header delivery section, this rule requires exactly one direct ram:ID child. It checks the number of elements, not whether the identifier text is empty or correct.

Why it matters

The Extended profile represents the identifier for each tax registration in one ram:ID field. Omitting or repeating that field does not match the required structure.

How to fix it

Check each tax registration block for the delivery party separately. Add a missing ram:ID or remove extra ram:ID elements within that block, keeping the correct identifier. If a registration is not required for your invoice, remove its whole ram:SpecifiedTaxRegistration block instead of leaving it incomplete. Export and recheck.
