If you don't want to track the goods movement of motor, follow this process.
- Equipment should have been created
- Create PM Order
- Mention PM02 control key
- PR will be generated automatically
- Create PO from PR
- Do GR once you receive the motor back
- Do TECO, Settlement & Business Completion
If you want to track goods movement---
- Create Serial Number Profile in Configuration (many threads available on this)
- Create Material Master for motor using Material type as Assembly
- Assign the serial number profile
- Configure Split valuation to capture different states of motor (new, defect, refurbish)
- Stock will be increased while purchasing new motor
- Installation will reduce the stock
- Dismantling will increase the stock again (to do the repair)
- Create Refurbishment order in IW81
- Assign the material & do goods issue
- Once motor is received, do GR in IW8W
- Then TECO, Settlement & Business Completion
Again insisting you to search in forum to get the details on Refurbishment, Installation / Dismantling, Serial Number Profile, Automatic / manual Equipment Creation, etc.,
