Hello.
I´m looking for any solution solving folowing situation:
For Production order is as a material used serialized item (lets say speedmeter PN001 to produce display board).
The display board is sent to warehouse and PO1 is closed.
Then PO2 for another (higher) BOM level is created and the display board is used as a component (for examle to build an airframe).
But during testing functions of the airframe the speedmeter PN001 is found defective and must be changed.
How can we send the defective speedmeter PN001 back to warehouse and get new one for PO2?
Note:
We do not fill As-build components in Manufacturing.
Thanks for help

Sorry - this question belongs to different section. Probably someone with warehousing experiences could also know...
