This figure illustrates that regardless of how a call is created, SSM searches for an appropriate set of defaults when it builds the call record. The technical work code is the default in Call Maintenance, and appropriate defaults are brought in. Defaults based on work code are used in a similar fashion in the Call Generator.

PM calls created as part of the scheduling associated with Contract Maintenance are always created with the PM work code (as defined with Call Management Control) and any defaults set up for it in Call Default Maintenance.

Installation calls created during invoice post are always created with the Install work code and any defaults set up for it in Call Default Maintenance.
