Inventory Changes

When a shipment is saved, Backbone MRP automatically records an inventory change for every part included in the shipment. The Inventory Changes tab shows a complete log of those adjustments so you can verify what was decremented and from which location.

Shipment Header

Before reviewing inventory changes, confirm the shipment header fields are correct:

Field Description
Order #The sales order this shipment fulfills.
Ship DateThe date the goods left your facility.
Ship ViaCarrier or shipping method (UPS, FedEx, LTL, Will Call, etc.).
Tracking #Carrier-issued tracking number for the package.
Ship-To LocationThe customer destination address for this shipment.

Action Buttons

  • Lock / Unlock — Locks the shipment once it is confirmed. Locked shipments cannot be modified. Unlock to make corrections.
  • Create Invoice — Generates an invoice for this shipment directly from the shipment record.
  • Print Packing Slip — Prints the packing slip document for this shipment.

Inventory Changes Table

Each row in this table represents one inventory adjustment triggered by the shipment.

Column Description
Part NumberThe part that was shipped and whose inventory was decremented.
DescriptionPart description from the catalog.
LocationThe inventory location (warehouse bin, shelf, etc.) from which the quantity was pulled.
Quantity ShippedThe number of units removed from inventory.
Quantity BeforeInventory on hand immediately before this shipment.
Quantity AfterInventory on hand immediately after this shipment (Before − Shipped).

Verifying Inventory Changes

  1. Open the shipment from the Sales → Orders editor (Shipments tab) or from the customer record's Shipments tab.
  2. Click the Inventory Changes tab.
  3. Confirm each part row shows the correct quantity shipped and the resulting on-hand level.
  4. If a discrepancy exists, unlock the shipment, correct the shipped quantity, and save. The inventory change will be recalculated.
Locking a shipment: Once locked, the inventory changes are considered final. Unlocking and re-saving will reverse and reapply the inventory adjustments. Only unlock when a genuine correction is needed.
Invoicing from this tab: The Create Invoice button on this screen is a shortcut — it produces the same invoice you would create from the order's Invoices tab. The resulting invoice is linked to both the order and the shipment.
