Purchase Order Amount Validator

Validates that the purchase order total is within the supplier's minimum and maximum order amount limits.

Overview

The Purchase Order Amount Validator checks that the total value of the purchase order falls within the supplier's configured order amount limits. Both a minimum and maximum limit are supported. Violations are reported as warnings, so orders can still be saved and processed — the warning serves as an advisory notice to the buyer.

Behavior

If no supplier is set on the purchase order, validation is skipped
Looks up the supplier and checks whether MinimumOrderAmount or MaximumOrderAmount is configured
If neither limit is set, validation is skipped
If the order currency differs from the supplier's preferred currency, the limit values are converted to the order currency before comparison
If the order total is below the minimum, adds a warning to the order
If the order total is above the maximum, adds a warning to the order
If both checks pass, any existing amount error is removed

Configuration

Supplier order amount limits are configured in Supplier Configuration. The validator uses ICurrencyService for currency conversion when the order and supplier currencies differ.
