Error

FX-SCH-A-000024: An invoice can name at most one business process

In short

Error: fails the selected checks.

FX-SCH-A-000024 means rsm:ExchangedDocumentContext contains more than one business process entry for BT-23. Remove the extra ram:BusinessProcessSpecifiedDocumentContextParameter elements, keeping the entry you need.

On this page

What it means

Within each rsm:ExchangedDocumentContext, the test allows zero or one ram:BusinessProcessSpecifiedDocumentContextParameter. It counts entries even if they contain the same identifier. This rule does not itself require a business process entry.

Why it matters

The profile provides at most one business process entry in the document context. Repeating it exceeds that structural limit.

How to fix it

Check the business process identifier (BT-23) in your export. Inside rsm:ExchangedDocumentContext, keep no more than one ram:BusinessProcessSpecifiedDocumentContextParameter. Do not remove a required identifier merely because this particular rule permits its absence. Export again and recheck.
