Exclude Markups Linked to Cancelled Purchase Order Lines from Purchase Order Totals

Currently, when a purchase order line is cancelled, any markups or charges that were previously associated with that line remain included in the purchase order totals. This leads to an incorrect total value, as the markup from a now-irrelevant (cancelled) line still contributes to the PO total calculation.

This behavior can cause confusion and inaccurate financial reporting, especially when users rely on the purchase order totals for cost validation or approval processes.

Expected Behavior:

When a purchase order line is cancelled, any markups or charges linked to that line should be automatically excluded from the purchase order totals, ensuring that the total value accurately reflects only the active lines.

Business Impact:

Prevents incorrect financial totals on purchase orders.

Reduces manual effort needed to review or remove markups after cancellations.

Improves accuracy and transparency for users handling large or complex POs with multiple lines and charges.
