Using BOMs and Routings in Calls
When you define an item in Service Item Maintenance (11.3.7), you can specify a repair, installation, and preventive maintenance (PM) BOM and routing, which are used as follows:
When the system generates a PM call for the item or you create a call with the PM work code in Call Maintenance, the system uses the PM BOM and routing.
When the system generates an installation call during invoice post or you create a call with the install work code in Call Maintenance, the system uses the installation BOM and routing.
When you specify other work codes in Call Maintenance, the system uses the repair BOM and routing.
You can change these defaults the first time you view the call in CAR.
Use BOMs and routings to streamline data entry for standard repair sequences in CAR. When you specify BOMs and routings, the system:
Enters routing operations into the Labor/Expenses frame
Enters any BOMs associated with specific operations as items for that operation in the Item Usage frame
Enters items from the top-level service BOM into the first operation that has no items of its own
Routing and BOMs Loaded into CAR illustrates how service BOMs and routings are defined and then loaded into CAR.

Routing and BOMs Loaded into CAR
In addition to providing labor/expense detail, routings can affect the cost of labor. Standard cost for labor is derived from the work centers associated with routing or standard operations. If you do not use these, the system calculates standard costs using the labor rate for the Service Work Center in Call Management Control.
Note: If you do not use service BOMs and routings, you must manually enter the operations and items you used for the repair in CAR, unless you order items with a material order (MO).
When a BOM is initially loaded in CAR, the system does not check to determine if sufficient inventory exists in the default site and location. These checks are not done until you actually execute the item usage frames.
