## Official rule text

A Payment account identifier (BT-84) shall be present if Credit transfer (BG-17) information is provided in the Invoice.

## Why did my invoice fail BR-50?

When credit transfer payment details (BG-17) are given, the Payment account identifier (BT-84), i.e. the account/IBAN the buyer should pay into, must be present. Otherwise the buyer has payment means but no account to remit to.

## Common causes

- cac:PayeeFinancialAccount was included but its cbc:ID (IBAN/account number) was empty or missing.
- A credit-transfer payment means code (30/58) was used without any PayeeFinancialAccount.
- The IBAN was placed in a note or FinancialInstitutionBranch instead of PayeeFinancialAccount/ID.

## How do I fix it?

```
In cac:PaymentMeans/cac:PayeeFinancialAccount add <cbc:ID>DE89370400440532013000</cbc:ID> (the payee IBAN or account number).
```
