Validation message
Explanation
The Document Reference element for an invoiced-object reference may only be used at line level, not at document level.
How to fix
Move the Document Reference to line level. (Typically a software-side issue, not user input — raise this with your invoicing software vendor; if you're receiving the invoice, ask the sender to address it with theirs.)
