Purchase Order Zero Quantity Validator

Overview

The Purchase Order Zero Quantity Validator checks that all line items on a purchase order have a quantity greater than zero. Any line item with a quantity of exactly 0 is flagged as an error on both the line item and the order, blocking the order from being saved in an invalid state.

Behavior

1. If the purchase order has no line items, validation is skipped
2. Iterates over all line items
3. If a line item has Quantity == 0, an error is added to both the line item and the order
4. If a line item has a quantity greater than zero, any existing zero-quantity error is removed from that line item
5. If no zero-quantity lines were found, the zero-quantity error is removed from the order as well
