Hello Guys, I have a process Model "A" who calls a subprocess &qu

For unattended nodes(script tasks, write to db, etc) you can use assignment as "Run as whoever started or designed this process model".
But your error "Error: Attended nodes must be assigned." indicates that there is an attended node like user input task which definitely needs assignment.

But if you still want no assignment then as a hack/alternative you can give the user input task assignment as -1 which will let it save and publish the process model.
The task will be visible to all users with System Administrator privilege with "[Group Name Not Available]" text in the "Sent to" field.

Hope this information is helpful.
