Assembly, disassembly and internal material movements

Assembly consumes components and creates finished goods; disassembly reverses that direction. Material issues and returns track internal use.

Steps

1. Maintain the composition with correct component units and quantities; never make an item a component of itself.
2. Select the finished item, assembly quantity and warehouse, then expand its BOM or enter components and check costs.
3. After approval, verify finished-stock increases and component decreases. Check the opposite directions for disassembly.
4. For material issues, select department, person, warehouse and quantity; use material returns for goods physically returned.
5. Reconcile handover evidence and avoid issuing the same materials again through another movement type.
