This activity is used to create or modify a resource break. Resource breaks represents tools or persons unavailability due to certain practical reasons like absence from work or some maintenance work on tools itself. When work orders or PM action occurrences are scheduled using Maintenance Planning Board (MPB), the MPB will schedule them (work orders and PM action occurrences) considering resource breaks that are in Scheduled state.
This activity requires the existence of a site to which you can connect the resource break. Furthermore, you must have defined the resource to which the resource break applies.
