IPSI charge VAT rate must not be negative

Error BR-AG-07 EN 16931

In a Document level charge (BG-21) where the Document level charge VAT category code (BT-102) is "IPSI" the Document level charge VAT rate (BT-103) shall be 0 (zero) or greater than zero.

Mandatory rule: As long as it is violated, the invoice is invalid and will be rejected by validators.
What is wrong

The VAT rate of the document-level charge is less than zero. For a charge with VAT category M, ram:RateApplicablePercent must not be negative.

What the rule means

A negative VAT rate conflicts with the rule for a document-level charge in category M, which requires a rate of at least zero.

Affected fields BG-21 BT-102 BT-103
Please set the IPSI charge VAT rate to zero or more

The VAT rate for the document-level charge with VAT category M is below zero. Adjust the value so that it is zero or higher.

What to do
  1. Check the value of ram:RateApplicablePercent for the relevant charge.
  2. Check the VAT rate value in AddTradeCharge(...).
  3. Generate the invoice again and validate it.
