Schedule a Workflow
You can call a workflow from a workflow and schedule it to start at a later time and date.
You schedule workflows in another workflow by using the Schedule Workflow element.
Prerequisites
n
Open a workflow for editing in the workflow editor.
n
Add some elements to the workflow schema.
Procedure
1 Drag a Schedule Workflow element from the Generic menu to the appropriate position in the
workflow schema.
2 Search for the workflow to call by typing part of its name in the text box.
3 Select the workflow from the list and click OK.
4
Click the Edit icon ( ) of the Schedule Workflow element in the workflow schema.
5 Click the IN property tab.
A parameter named workflowScheduleDate appears in the list of properties to define, together with the
input parameters of the calling workflow.
6 Click Not set for the workflowScheduleDate parameter to set the parameter.
7 Click Create parameter/attribute in workflow to create the parameter and set the parameter value.
8 Click Not set for Value to set the parameter value.
9 Use the calendar that appears to set the date and time to start the scheduled workflow and click OK.
10 Bind the remaining input parameters to the scheduled workflow in the IN tab of the scheduled
workflow element.
11 Bind the required output parameters to the Task object in the OUT tab of the scheduled workflow
element.
12 Define the exception behavior of the scheduled workflow element in the Exceptions tab.
13 Click Close.
14 Click Save at the bottom of the workflow editor.
You scheduled a workflow to start at a given time and date from another workflow.
What to do next
You can call multiple workflows simultaneously from a workflow.
Prerequisites for Calling a Remote Workflow from Within Another Workflow
If the workflow that you develop calls another workflow that resides on a remote Orchestrator server,
certain prerequisites must be fulfilled so that the remote workflow can run successfully.
n
All input parameters of the remote workflow must be resolvable on the remote Orchestrator server.
n
All output parameters of the remote workflow must be resolvable on the local Orchestrator server.
