What it means
In the Basic WL, Basic, EN 16931 and Extended profiles of Factur-X and ZUGFeRD, each contract reference block in the header trade agreement must contain one ram:IssuerAssignedID. This rule does not require a contract reference or check its value.
Why it matters
The contract number links your invoice to the agreement it refers to. One identifier keeps each reference unambiguous.
How to fix it
Check the contract reference in your invoice data. In XML, add the correct BT-12 value in ram:ContractReferencedDocument/ram:IssuerAssignedID under ram:ApplicableHeaderTradeAgreement, or consolidate repeated ID elements into one. If the invoice should not refer to a contract, remove the whole contract reference block rather than leaving it empty. Export and recheck your file.
