Unable to Mark Complete an activity on Playbook

[AnirudhKumar]

Hey Folks!

On my playbook activity, I have a Mark Complete button. When I click it, I see an error message at the top saying , "This activity does not support the Complete state"

This is a custom activity, and the subflow that runs on it is also custom.

Any ideas why this may occur?

Enlighten us, @Brad Tilton ...

Hi!  If you're still looking for an answer to this, this is due to ACLs.  If the record does not have an assignment group set and it also doesn't have an assigned to set... then anyone (snc_internal/snc_external) can mark it as complete.  Otherwise, you either have to be a member of the assignment group, or the assigned to.  All due to sys_flow_data ACLs.
