Sale Order Line Initial Quantity

This module keeps a memory of the quantity that was originally ordered on each sale order line. When a sales order is confirmed, the quantity present at that moment is saved as the "Initial quantity" on every line.

On the sale order form, a new read-only column called "Initial quantity" appears in the order lines list. It is only shown when at least one line's current quantity differs from its saved initial quantity and the order is in a confirmed or done state; otherwise the column stays hidden to keep the screen clean.

A hidden indicator field on the order, "Initial Quantity Changed", is computed automatically. It becomes true when the order is confirmed or done and any line has a quantity different from its initial quantity. This is what controls the visibility of the column.

• The module extends sale.order and sale.order.line.
• It adds the stored field product_uom_initial_qty on order lines and the computed field initial_qty_changed on orders.
• It overrides the order confirmation action to record the initial quantities.
• It modifies the standard sale order form view to add the new column.

No new menus or reports are added; everything happens inside the existing Sales order screen.
