CII-SR-471
Validation message
Explanation
A document-level allowance or charge (BG-20/BG-21) may carry its percentage only once. (The rule's original message refers to the VAT category; what it actually checks is the repeated percentage.)
How to fix
Give each allowance or charge exactly one percentage; record different rates as separate allowances or charges. (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.)
