How does the submission of inputs in the Decision Workbench application trigger the subsequent process in the parent process workflow?
The subsequent process can be configured into the Decision Workbench Activity in the parent process workflow.
The activity has been built to always execute the subsequent process when the SME takes decisions in the Workbench.
It is up to the process designers, whether he/she wants to use the inputs provided by the SME and send it to the subsequent process.
For this, they need to configure Subsequent process Input.
