Explanation
Updating the Resource as not available allows marking a resource as unavailable for a specific time period due to sickness, vacation, or other reasons[ . Selecting the affected Service Appointments and pressing
"Schedule" allows rescheduling multiple service appointments at once based on predefined criteria such as travel time or priority[28. Dragging and dropping the Service Appointments to other available Resources and running Optimization would reschedule service appointments manually and then run an optimization process that could override the manual changes[29. Asking the Customer Service Rep to call the customers and manually re-schedule for another day would not use the scheduling features of Field Service and could result in customer dissatisfaction or missed service level agreements. Changing the Scheduling Policy to "High Intensity" and activating the Background Optimization process would change the optimization criteria for all service appointments and run an optimization process in the background that could take a long time to complete[30.

Explanation
Products consumed are records that track the products used during a service appointment[32]. A custom installation date field on products consumed would allow reporting on the volume of products installed within a specific timeframe by filtering on the installation date field values[33]. A work order related list on asset would show the work orders associated with an asset, but not the products installed. Field history tracking on asset would track field changes on an asset, but not the products installed. The standard installation date field on asset would show when an asset was installed, but not the products installed. References:
