Mass change rule authorization

Dear experts,

I want to allow for several users to allow to create and release substitutions on asset master data. But when user release a worklist, warning message appears:

<i><b>"No administrator found for the task"

"Message no. 5W141"</b></i>

What should I do, what parameter is missing on user profile? We definitely want to grant to some users rights to create and release substitutions, so do we need to grant System Administrator rights?
