Broadcom Support does not recommend to use an external dependency that depends on a task within the same workflow, as shown in the screenshot below: the task which has an external dependency, will need to be manually skipped.
Products: Automic Automation Engine v10, v11,v12
Operating System: All
Please use one of the option below:
Option 1: Use a Pre-Condition on the first task of the workflow as shown below. The task that is expected or required must be executed outside the workflow.
Option 2: Use an external dependency of a task outside the workflow.
Option 3: create a sub-workflow with the flag creation JOBS disconnected inside it, that way the main workflow will finish as soon as the sub-workflow starts.
