Creating step types

Disponible avec une licence Standard ou Advanced.

Step types are the building blocks of your workflows. They provide basic information as to what happens when the step is executed and how it is represented. When a step type is added to a workflow, it becomes a step but still references all the properties of the original step type. Multiple occurrences of a step type can appear in a single workflow.

Step types have the following components:

• Profile—Contains basic information about the step type
• Description—An optional setting that allows you to configure additional information about what the step will do or what the user should do to complete the step
• Execution—Defines the step behavior of the individual steps when executed in a workflow

Execution types

The following step execution types are available:

Step execution types

Type	Description
Procedural	Manual step with no managed execution
Custom step object	Calls a custom class implementing IJTXCustomStep
Open File	Opens a file from the workflow
Executable	Starts an executable
Launch URL	Opens a URL
Ask Question	Asks the user a question with configurable answers

Remarque :

Custom steps built using IJTXCustomExecute can be run with the current version of ArcGIS Workflow Manager (Classic). However, you are encouraged to upgrade your step libraries to take advantage of the new options with IJTXCustomStep. See the developer kit for help upgrading step libraries.

Building step types

The following subsections explain how to build a step type.

Defining basic step type properties

With the basic step properties, you provide descriptive information for the steps that comprise your Workflow Manager (Classic) system.

1. Open the Workflow Manager Administrator and connect to your Workflow Manager (Classic) database.
2. In the Administrator, browse to the Step Types folder under Job Components.

   The list contains all the currently configured step types. If no step types are configured, the list will be blank.

3. Right-click the folder and click Add Step Type or choose an existing step and click Edit Item.

   The Step Type Properties dialog box appears.

4. Provide a name and description for the step type.
5. Choose the indicator for the step.

   This setting defines the shape of the step in the workflow.

6. If the user needs to interact only with the logic of the step, check the Hide WMX While Running check box. This setting is most useful when the step will open another application with which the user will interact with, such as ArcMap.

   If it's fully automated, don't check the box.

Configuring step descriptions

Step descriptions allow you to provide specific information about the step that will be shown to your users in the Workflow Manager (Classic) client application.

1. On the Step Type Properties dialog box, click the Description tab.
2. Choose one of the following options to add a step description:
   • URL Link—Choose this option if all Workflow Manager (Classic) users have access to the link. This can be a link to a web page or an .html document you've authored.
   • Embedded HTML—Choose this option to provide simple text or HTML formatted text that will be available to all users, regardless of how they access the Workflow Manager (Classic) system.

   Remarque :

   If the step description uses Unicode characters, make sure that your HTML content contains a meta tag that specifies the character encoding, for example, <meta content="text/html; charset=UTF-8" />.

   

   Use step descriptions to provide detailed information about the step to the user.

Configuring custom object step execution

The Execution tab allows you to configure the behavior of the individual steps when they're executed in a workflow.

1. On the Step Type Properties dialog box, click the Execution tab.
2. Click the Custom Step Object execution type button.
3. Click the CLSID/ProgID browse button and choose the step to use.

   

   Choose what should happen when the user executes or reaches this step in the workflow.

4. Click OK to close the Browse for Custom Steps dialog box.
5. Click List Expected Arguments to see a list of required and optional arguments for the custom step you chose.
6. Provide any required arguments.
7. Provide any optional arguments.
8. Click Validate Arguments to ensure that the arguments you provided are valid.
9. Choose the supported platform.
10. Click OK to save changes to the step type and close the Step Type Properties dialog box.

    Remarque :

    • Some custom Workflow Manager (Classic) steps can accept dynamic arguments using tokens.
    • Arguments should be separated using spaces. In the case where the argument itself contains spaces, enclose the argument in double quotes (").
    • Not all custom steps that are included with Workflow Manager (Classic) can be executed on all platforms. The steps are divided into the following categories:
      • All Platforms: ArcGIS Pro, ArcMap, ArcCatalog, and ArcGIS Server
      • ArcGIS Desktop only: ArcMap and ArcCatalog
      • ArcGIS Pro and ArcGIS Desktop only: ArcGIS Pro, ArcMap, and ArcCatalog
      • ArcGIS Pro only

Configuring open file execution

The Execution tab also allows you to open a file through a Workflow Manager (Classic) step.

1. On the Step Type Properties dialog box, click the Execution tab.
2. Click the Open File execution type button.
3. Click the File Path browse button.
4. Browse to the file that you want Workflow Manager (Classic) to open during the execution of this step.

   Remarque :

   This file will be stored in the database. If it's large, you may need to work with your database administrator to increase the MAXBLOBSIZE setting.

5. Click Open to associate the file with this step.
6. Click the Supported Platform drop-down arrow and choose the supported platform for the step.

   The Open File execution type works on both the desktop and the server.

7. Click OK to save the step type and close the dialog box.

Configuring executable execution

The Execution tab also allows you to run an executable through a Workflow Manager (Classic) step.

1. On the Step Type Properties dialog box, click the Execution tab.
2. Click the Executable execution type button.
3. Browse to the location of the executable you want this step to execute.
4. Provide any arguments for the executable.

   Remarque :

   Keep in mind that tokens can be entered here.

5. Click the Supported Platform drop-down arrow and choose the supported platform type.
6. Click OK to save the step type and close the dialog box.

   Remarque :

   Arguments should be separated using spaces. In the case where the argument itself contains spaces, enclose the argument in double quotes (").

Configuring launch URL execution

This option allows you to open a web browser with a specified URL through a Workflow Manager (Classic) step. This step can be configured with a web map or web editing application URL and the [JOB:AOI_ENVELOPE] token to zoom to the location of interest of the job on the map after it's opened. Append the extent=[JOB:AOI_ENVELOPE] to the web map URL, and prefix the parameter with ? if the extent is the first parameter in the URL, or prefix with &, for example, http://www.arcgis.com/home/webmap/viewer.html?extent=[JOB:AOI_ENVELOPE].

1. On the Step Type Properties dialog box, click the Execution tab.
2. Click the Launch URL execution type button.
3. Provide the path that you want to launch when Workflow Manager (Classic) executes this step.
4. Click the Supported Platform drop-down arrow and choose the supported platform.

   The Launch URL execution type works on both the desktop and the server.

5. Click OK to save the step type and close the dialog box.

Configuring ask question execution

The Execution tab also allows you to define steps that ask your users questions when executed in the Workflow Manager (Classic) step.

1. On the Step Type Properties dialog box, click the Execution tab.
2. Click the Ask Question execution type button.
3. Click the Question browse button.

   The Question Editor dialog box appears.

4. Provide the question to be asked.
5. Provide a title for the dialog box that will appear to the user when the step is run.
6. Provide the possible responses in the text box on the left.
7. Click Add to add them to the options or press Enter as a shortcut and add another response right away.
8. Check the Include Note Field check box to allow users to provide feedback.

   The user is presented with a text box to provide the reason for their selection. The value entered is appended to the job history as a comment.

9. Click OK when you're finished.

Remarque :

Take note of the return value in this list. If you're routing your workflows based on the response from the question, this value will be the return code from the step. Use this return code in the path properties for automatic advancement of the workflows.



Provide the question you want to ask as well as possible responses on the Question Editor dialog box.

10. Click the Supported Platform drop-down arrow and choose the supported platform for the step.

    The Ask Question execution type works on both the desktop and the server.

11. Click OK to save the step type and close the dialog box.

Cloning step types

The step types in your Workflow Manager (Classic) repository can be reused. You can make a copy by cloning the step type along with all the defined properties.
