This article describes the business logic of the Production document for Assembly and Disassembly operations when the Separate Inventory and Financial Documents option is enabled for the relevant warehouses.
1. Assembly
When Separate Inventory and Financial Documents is enabled, an additional Goods Receipt Note (GRN) must be created to register the produced goods in the warehouse.
...
After posting the Goods Receipt Note, the produced goods are correctly reflected in warehouse stock.
2. Disassembly
The Disassembly process is different from Assembly.
...
Finished Good → Goods Dispatch Note → Production (Disassembly) → Goods Receipt Note → Components + Scrap
Goods Dispatch Note
The Goods Dispatch Note is used to register the issue of the finished good from the warehouse for disassembly.
...
In other words, the GDN represents the outgoing side of the Disassembly process: the finished good leaves the warehouse and is provided for disassembly.
Goods Receipt Note
The Goods Receipt Note is used to register the goods and scrap obtained as a result of the disassembly.
...
The GRN represents the incoming side of the Disassembly process: the components and scrap resulting from the operation are received into the warehouse.
3. Why are both GDN and GRN required?
The need for both documents is related to the fact that Disassembly consists of two different inventory movements.
...
When Separate Inventory and Financial Documents is enabled, these warehouse movements are handled through separate inventory documents rather than being fully completed by the Production document itself.
Therefore:
Document | Inventory operation | Purpose |
|---|---|---|
Goods Dispatch Note (GDN) | Outgoing | Issue the finished good from the warehouse for disassembly |
Production – Disassembly | Production operation | Perform the disassembly and determine the resulting components/scrap |
Goods Receipt Note (GRN) | Incoming | Receive the resulting components and scrap into the warehouse |
This separation explains why both documents are required to complete the warehouse-side process.
