When you associate an MO with a call, you must associate each line item with a particular call line. When you access the call line in Call Activity Recording, the system displays a list of MO line items ordered for it. The engineer can select some or all of these items, which the system loads into the Item Usage frame of CAR.

Loading MO lines simplifies the recording of consumed and exchanged items ordered with MOs. Once items are loaded, you can modify the usage records like any other records in CAR.

If you select an MO line but do not issue the inventory, the system removes it from the usage detail and lets you reload it. The system keeps track of items consumed on the MO and continues to present the Material Order Selection frame until you have consumed or returned all MO items.
