WorkflowExecutionResult example

The following script shows how a return code can be obtained from a step's execution.

import arcpy
import sys
import traceback


# Define the callback response function. In this case it will prompt the user using the console to respond.
def callback(question, responses):

    # Print out the expected responses
    for resp in responses:
        print("[%i] %s" + (resp[1], resp[0]))

    # Prompt the user to respond
    val = int(input("%s - %s: " % (question[1], question[0])))

    # Return their response. Currently only returning the value, but could also return a note (for questions) and the name of the response
    return val, "", ""


# Establish a connection to a Workflow database
conn = arcpy.wmx.Connect(r'c:\test\Workflow.jtc')

# Get a Job for Execution
job = conn.getJob(77601)

try:
    # Execute the current Step in the Job - a LaunchArcmap step without Proceed to Next enabled
    result = job.executeStep(callback=callback)

    # A Launch ArcMap step will not finish automatically it will be complete after the user indicates it is.
    if not result.finished:
        t = input("Please press any key and hit enter when finished step") 

        # Finish the step and Mark as Complete
        result.finishStep(callback=callback) 
        job.markStepAsComplete(callback=callback)

        # Run the next step in the workflow
        result = job.executeStep(callback=callback)

    print("Executing a 2nd step returned %i" % result.returnCode)
    
    # Mark the step as complete
    job.markStepAsComplete(callback=callback) 

except wmx.WorkflowExecutionStepError as e:
    print("Step failed to execute:")
    print("-"*60)
