User Interact Step Restrictions
The following restrictions apply if you define a user interact step:
A Workflow Process that runs in the Workflow Process Manager server component must not contain a user interact step. If the workflow runs in background mode or in batch mode, then it cannot include a user interact step.
Siebel CRM supports the user interact step only if a script or a runtime event starts the Workflow Process, and only if it runs this Workflow Process locally in the Application Object Manager.
You cannot use the user interact step to display or start the Search Center.
The user interact step or any activity that starts in the background must not interfere with the work that the user is performing.
