FX-SCH-A-000656: Add the buyer agent's global identifier scheme

In short

Error: fails the selected checks.

FX-SCH-A-000656 means a ram:GlobalID for your buyer agent is missing its schemeID attribute. Add the attribute with the code for the numbering scheme that issued the identifier.

On this page

What it means

Every ram:GlobalID inside ram:BuyerAgentTradeParty under ram:ApplicableHeaderTradeAgreement must have @schemeID. This test checks only attribute presence. An existing but empty attribute passes this test; permitted non-empty codes are checked by FX-SCH-A-000657.

Why it matters

The scheme identifies the numbering system used for the global identifier.

How to fix it

Confirm the identifier's numbering scheme with the buyer agent. Add schemeID to the affected ram:GlobalID using the matching permitted code, for example 0088 for a GLN or 0060 for a DUNS number. Do not choose a scheme just because its code passes a check. Re-export and recheck your invoice.
