What does this mean?

Typical causes

A third party payment was added without an amount.
The element cbc:PaidAmount in cac:PrepaidPayment is empty.

How to fix the error

State the amount in the element cbc:PaidAmount of every cac:PrepaidPayment, with at most two decimals (BR-DEX-13) and in the invoice currency (BR-DEX-14).
Then check the amount due (BT-115) according to BR-DEX-09.
Generate and validate the invoice again.
