The two ways of automatically entering items in CAR—through MOs or service BOMs—normally are separate alternatives. You can use them together, but you could enter more items than you intend.

If an engineer orders items with an MO for a call, they must be loaded and consumed in CAR. If you also attach a BOM to the item, the same items could be loaded again, resulting in duplicate items appearing in the usage frame. You might also get duplicates if you release a quote that has details about items needed, then order the items on an MO.

You must decide which method best fits your business practices and establish procedures to prevent overlaps.

To warn you of possible duplicates, the system checks the call when you create an MO for it. If the call line has items generated from a BOM, a warning displays.
