Glossary

Common terms used in work orders.

Term	Meaning
Build target	The item a work order is making, at one exact released revision. A product or an assembly at any depth.
Closed	All costs are final. No further changes can be recorded against the order.
Completed	Production is finished. Late corrections — scrap, reversals, labor — are still possible.
Explode	To calculate the component parts needed to build an assembly.
Gross qty	Net plus overage. What actually gets reserved.
Issue	The movement that takes material out of stock and into a build. Costed at the value of the lots that left.
Lot	A batch of stock sharing an origin and a cost. Finished units are received into a lot of their own.
Material plan	The parts and quantities needed for a build, calculated from its BOM.
Net qty	What the structure calls for, before overage.
On hold	Paused, with a reason. Keeps its reservation.
Operation	A step of the build. Carries its own material and its own completion.
Overage	Extra material added to a requirement to cover expected process loss. Set on the part.
Reason code	A coded entry from one of four configured lists — hold, cancel, reject, scrap — recorded alongside the note.
Receipt	A batch of finished units coming back as stock, with its own cost and its own lot.
Release	The mechanism that moves stock. A work order never touches inventory directly.
Reservation	Stock held for one build and no other, placed when the order is created. Still on the shelf, just spoken for.
Reversal	Undoing an issue that was wrong. A deliberate movement of its own, not an undo button.
Shortfall	What the reservation could not cover. Written onto the purchase step as work to be done.
Step	See Operation.
Transition	A change from one status to another, such as Draft to Pending.
Unplanned material	A part consumed by a build that the structure did not call for, recorded as such.
WIP	Work in progress. Where the value sits between material being issued and units being received.
