Item net price MUST equal (Gross price - Allowance amount) when gross price is provided.

Explanation:
Net price must be gross price minus discount if gross price is specified.

 

Invoice line net amount MUST equal (Invoiced quantity * (Item net price/item price base quantity) + Invoice line charge amount - Invoice line allowance amount.

Explanation:
In plain text, the rule states:
Quantity * (Base Price / Base Quantity)) + Charge - Allowance + 0.02 >= Line Amount
AND
Quantity * (Base Price / Base Quantity)) + Charge - Allowance - 0.02 <= Line Amount

What we can correct are typographical errors, for example:
1) Line Amount = -100 and Quantity = 1 -> Quantity = -1
2) Base Price < 0 -> Base Price > 0 (see also [BR-27])

NOTE! We ONLY correct pure typographical errors.
