Prevents the remaining tasks in a job from starting or being created. The active task and its task group job will still complete.
A task group, or parent job, is composed of a series of tasks, or child jobs.
This tool can be run while a task or task group is running if there is no longer a need to complete the remaining tasks.
This tool is intended for use with the topographic mapping production management workflows and requires a properly configured ArcGIS Workflow Manager (Classic) repository.
The TOPO_TASK_PROPERTIES table is used to determine which tasks remain for a job, and the table is updated to indicate that the remaining tasks no longer need to be run.
Use the ID of the parent task group as the Job ID parameter value, not the child task job.
| 标注 | 说明 | 数据类型 |
Job ID | The job ID of the parent ArcGIS Workflow Manager (Classic) task group job that contains the task list derived from the Set Task List tool. | Long |
Input Database Path (可选) | The ArcGIS Workflow Manager (Classic) database connection file that contains the job information. If a connection is not specified, the current default ArcGIS Workflow Manager (Classic) database will be used. | File |

The following stand-alone script demonstrates how to use the CancelRemainingTasks function in Python.
# Name: CancelRemainingTasks_sample.py
# Description: This script attempts to run a child job. If there is an exception
# and the child job fails to run a step, the Cancel Remaining Tasks tool is
# called to cancel the remaining tasks for parent job.
# Import System Modules

# Setting Local Variables
job_id = 15
workflow_database = r'C:\Data\Workflows\Testing.jtc'
#Connect to the workflow database
connection = arcpy.wmx.Connect(workflow_database)
#Get a Job for Execution
job = connection.getJob(job_id)
# Execute the job
try:
result = job.executeStep()
#Raised when a step in the workflow encounters an execution error
except wmx.WorkflowExecutionStepError as e:

# get the id of the parent job

# If an exeception happens, call the Cancel Remaining Tasks tool to cancel
# all the remaining tasks for the parent job.
