FX-SCH-A-000501: Check the seller's global identifier scheme

In short

Error: fails the selected checks.

FX-SCH-A-000501 means the scheme code on the seller's global identifier (BT-29) is not in the identifier scheme list used by the Basic profiles of Factur-X and ZUGFeRD. Use the listed four-digit ISO 6523 code matching the identifier, such as 0088 for a GLN or 0060 for a DUNS number.

What it means

This rule checks a non-empty schemeID attribute on ram:SellerTradeParty/ram:GlobalID against the profile's identifier scheme list. It checks the scheme code, not the identifier's value. It does not establish whether the identifier or its scheme is required elsewhere.

Why it matters

The scheme identifies the numbering system used for the seller's identifier.

How to fix it

Check which numbering system your seller identifier belongs to. Correct schemeID on ram:SellerTradeParty/ram:GlobalID under ram:ApplicableHeaderTradeAgreement to the matching listed code, preserving leading zeroes. Do not change or delete the identifier just to make an unrelated scheme fit. Recheck the corrected file.
