What it means
For each ram:ReceivingAdviceReferencedDocument under ram:ApplicableHeaderTradeDelivery, this rule counts its ram:IssuerAssignedID children and requires exactly one. It applies to the EN 16931 and Extended profiles. It counts elements, not filled-in numbers: one empty identifier element satisfies this count test.
Why it matters
Each receiving advice reference has one designated element for its reference number. The element count and the presence of a meaningful number are separate requirements.
How to fix it
If you need the receiving advice reference, keep one ram:IssuerAssignedID inside ram:ReceivingAdviceReferencedDocument and enter the receiving advice number. Remove any duplicate identifier elements. If you do not need the reference, remove the whole ram:ReceivingAdviceReferencedDocument container rather than just its identifier. Export and recheck your invoice.
