A resource break is a period of time during which a resource is unavailable for normal processing. After a resource break is created, the Constraint Based Scheduler (CBS) can schedule and account for it in its calculations of production time.
A resource break can be one of two types: maintenance or manual. A maintenance break is automatically created by the system from information received from IFS/Maintenance. A manual break, by contrast, is entered by a user against a specific resource. Any combination of work center resources, tools, and laborers can be associated with a manual resource break.
Both types of breaks can be moved in time in the Scheduling Server, but only a manual break can be moved after its end date range.
When a manual resource break is first entered, it has Proposed status. After it is promoted to Unscheduled, it is transferred to the Scheduling Server. The resource break does not affect the shop schedule until it is given Scheduled status. It is possible to change a Scheduled resource break back to Unscheduled status. It is also possible to change the status of a Proposed or a Scheduled break to Finished, causing it to be removed from the Scheduling Server.
Resource breaks on non-CBS sites, sites for which the Scheduling Server has been disabled, or sites that use the APB for scheduling, work in a similar manner to resource breaks on sites that use the Scheduling Server. The main difference is the non-existence of a Scheduling Server into which the breaks can be passed.
When you set up a site to use the Advanced Planning Board (APB) and load shop orders to it, all resource breaks on the site that are in Unscheduled or Scheduled state are also loaded.
A resource break can be created via the Advanced Planning Board as well, whereas for sites that use the Scheduling Server you can only create them using the Rercsoue Break window. The break can be saved back to the database once it is scheduled.
A manual resource break which was created using the Resource Break window can be loaded to the Advanced Planning Board once it attains Unscheduled status. Initially it will be in Assigned state in the Advanced Planning Board, where it can be scheduled and saved back to the database. It then reaches the Scheduled state.
Note: The Shop Order Infinite Scheduler does not consider resource breaks during scheduling.
