Cancel Task

Explanation

This activity is used to cancel a planned or running task. When a task is in the Incomplete or Under Preparation status, the task can be cancelled without any additional validations. However, when the task is in either the Released or Started status, the status of the underlying operations will be used to determine whether the task can be cancelled or not. In such instances, it is only possible to cancel a task if the underlying operations are in the New, Released or Cancelled statuses.

Note: If you are canceling a task with the distribution type Work Order in a distributed environment, you must cancel the work order created for the task in IFS/Work Order Management. To do this, use the Status feature to set the status of the work order to Cancelled in either the Prepare Work Order or Report In Work Order window. However, if you are working in a non-distributed environment, you can cancel the task directly from the maintenance order.

Prerequisites   

• A valid cancellation cause must have been defined in basic data.
• You need to have access to the cancellation cause.

System Effects

• The task is cancelled and the status of the task set to New. This task is disconnected from the current maintenance order.
• If the task was in the Planned in Scope, Incomplete or Under Preparation status prior to canceling, cancellation history will not be generated.
• If the task was in either the Released or Started status prior to canceling, a history record will be generated in the Task Cancellation History. The task will be shown as a Cancelled task on the maintenance order. If the cancelled task is distributed with the distribution type Work Order or Execution Logic Structure, an additional history record with the Cancelled status will be generated in the Historical Work Order in IFS/Work Order Management.
• The task becomes a pending task or a convenience task again and can be redistributed.
• If the task is cancelled on a maintenance order with the Execution Logic Structure distribution type, the task operations will be removed automatically from the corresponding Execution Logic Structure (ELS).
• If the serial is defined as a vehicle serial and the cancelled task is the last running task (i.e., no other tasks exist) for the serial, the vehicle condition of the serial is automatically set to the vehicle condition code defined with the auto setting Set when last task is finished. For more information, refer to the activity Define Vehicle Condition.
• If the task being cancelled is from a previous maintenance program or from an obsolete modification, depending on the task type the due calculation for interval maintenance or modification will run automatically for the serial to calculate new due dates and values.
