Overruling activity definition
If an activity definition is linked to the same service plan and asset as another activity definition and it also includes equivalent activities, but is just linked to a different schedule, you can let it overrule the other activity definition. By letting an activity definition be overruled by another identical activity definition, you avoid generating unnecessary, duplicate maintenance activities.
In Maintenance Planner, at Definitions & Schedules > Activity definitions, you can select overruling activity definitions in the Overruled by schedule from… field. You can specify the margins for overruling in the Period of overruling schedule field.
 | Activity definitions with different maintenance regimes can also overrule each other, with one exception: activity definitions with a Non-cyclic maintenance regime cannot be overruled. |
Example
Three activity definitions, A, B and C are linked to the same asset and service plan:
Activity definition B is overruled by Activity definition A, within a margin of plus or minus six days.
Activity definition C is overruled by Activity definition B, within a margin of plus or minus three days. If Activity definition B is deactivated, Activity definition A will overrule Activity definition C.
