Hello Team, we have a requirement where the customer sends us the spare parts needed to repair their main assembly. Since these are customer owned units, is there a way costing can be negated for this. We are thinking if we can receive all the spare parts into a non-asset / non-nettable subinventory and issue them to the repair job from there. Please suggest in case of any options.

Thanks,Sudarshan
