Workflows used as subflows A workflow can launch another workflow as an activity. The parent workflow triggers the subflow and then waits for the subflow to complete before continuing. Run the workflow validation tool prior to publishing to detect missing subflows and other dependency problems, such as those involving update sets. The Workflows tab in the Workflow Editor contains a list of the workflows available for use as subflows. Figure 1. Workflows available to use as subflows Make sure that the selected subflow is active. If the subflow is inactive, the main workflow will hang with a Loading message. If you place an inactive subflow into a workflow, the subflow appears with a red banner, indicating that it cannot run. An active subflow is highlighted in blue when selected. Figure 2. Workflow with active subflows Subflows and the Create Task activityIf a workflow contains a Create Task activity that has executed on the current record, additional task activities in the workflow might not execute as expected.Pass a variable from a workflow to a subflowUse this process to pass variables from a parent workflow to a subflow.Prepare a subflowThis example describes the process of preparing a subflow for use in a parent workflow.Prepare a workflow to use a subflowAfter you create a subflow, use this procedure to prepare the parent workflow.
