Hi Modak,
screen shot attached here please find...
In Above screen shot is workflow log i.e custom wf , above wf contains 4 loops(stages) in every stage user was approved then wf triggered to next level . but in uwl every time from name is showing initiator only. ex: in this wf initiator is “hod-001” same name is displayed in from column for all users in UWL . I am facing same problem for standard wf also .
but we want "FROM" column name should be previous dialogue work item agent name means that who performed the action .
