I make a workflow inclue ad hoc activity. i can assign ad hoc activities to all users via orgadmin. But i can’t assign ad hoc activies to other users via regular user. When user tries to assign ad hoc activities to other users, receive "Secured Action. You do not have the necessary authorization for this operation. Contact your administrator if you believe you have received this massage in error". I attached the error screenshot.
I found out which policies cause the error. I have to make 2 rules to assign ad hoc activity. First one " wt.workflow.engine.WfAdHocActivity" grant "Read, create and modify". Second one " wt.workflow.engine.WfBlock" grant "Read, create and modify".
I don't know what "wt.workflow.engine.WfBlock" rule let user do? Could you help me about "wt.workflow.engine.WfBlock" effects?
