Hi , This scenario can be well handled if MRO sub-contracting is activated in your system. You can send equipments(attaching in components tab) through maintenance order to vendor. You have to mention Material provision indicator as material provided to vendor & then post goods movement. In inventory this quantity will show as Vendor stock & as soon as equipments are received stock will be reduced from vendor stock & show in your inventory.
In standard sap I dont think you can send equipments through maintenance order & view in inventory as stock provided to vendor.
In standard sap , I have used sub-contracting PO & material with split valuated to map this kind of scenario.
1. In sub contracting PO I have mentioned Material X with split valuation refurbished in main item & in components tab I have mentioned Material X with split valuated Scrap.
2. By using Stock Monitoring for Vendor post goods issue. Now component Material-X of valuation type scrap is transfered & will show in inventory as Vendor Stock.
3. MIGO after repair is done. Now Material-X of valuation type refurbished is updated in inventory & Material-X of valuation type-scrap is reduced from vendor stock.
4. MIRO for invoice receipt.
