Identifying Material And Labor Costs in Service Work Orders ???

I understand how to add materials and 'labor' (routings) to Service Work Orders on the Service Work order Entry Screen, but is there a something similar in Service WO (Sys 17) to 'Manufacturing Accounting' in Manufacturing WOs (Sys 48) that needs to run to create GL records for these and associate these costs with the Service Work Order?  I can't find anywhere that describes what needs to happen to create the GL entries. The documentation describes the AAIs (& DMAAIs) that need to exist, but does issuing materials and adding actual labor (and running Hours and Quantities update) write entries
